Official BMW Group historical technical-data pack for E9x-era BMW 3 Series Touring petrol models including the 318i and 320i, published for September 2009.

Useful for model-period technical facts and corroborating E91 320i applicability. It is historical press technical data, not a workshop repair manual.

Official BMW Group technical-data pack for the BMW 3 Series Touring, including 318i/320i specifications valid around September 2010.

Useful for checking model-period changes against the 2009 pack. Repair procedures and torque data still require the applicable BMW repair-information source.

Official BMW archived E91 model-year 2010 wheel/tyre applicability data that explicitly lists the 320i/iA with N43B20O0 among the standard-drive E91 variants.

Useful primary evidence that BMW's E91 MY2010 applicability tables included 320i/iA with N43B20O0. It does not establish the exact engine installed in a particular VIN and is not repair-information authority for procedure or torque data.

Official BMW VIN-based fuse assignment PDF service for supported vehicles. BMW states that online fuse assignment plans replace paper plans for vehicles from model year 2019 onward.

Do not present this as available for older vehicles such as an E91; BMW's public service states that the online plan applies to vehicles from 2019 onward and may report no online plan for unsupported VINs.

BMW-published SAE P-code list providing BMW fault-code descriptions. WrenchGuide uses it to verify the published code description only; vehicle applicability, causes, severity and repair guidance require separate evidence.

Official BMW TechInfo attachment. Treat each row as evidence for BMW's published code description only, not as a complete diagnostic test plan or proof that the code applies to every BMW engine/module/software generation. The direct attachment can move or disappear; SIB B12 32 14 is retained below as BMW's companion provenance for the list.

BMW service bulletin explaining that BMW-specific P/U codes should be read with a generic scan tool, looked up in BMW's SAE P-code attachment and matched back to the stored BMW fault before continuing diagnosis.

Useful provenance for BMW's P/U-code list and an explicit reminder that the P/U code is a diagnostic clue that must be mapped back to the vehicle fault, not treated as a parts order.

BMW bulletin identifying stored faults that were associated with repeat repair visits across E-series vehicles, including E90/E91/E92/E93, and directing technicians to complete the applicable ISTA test plan and follow its recommendations.

The bulletin establishes BMW's published description and the need to diagnose the listed stored code. It does not prove that every listed code applies to every engine/module combination inside every chassis named by the bulletin.

BMW diagnostic bulletin for N54 DME faults 29DC, 29F2 and 2FBF, including associated 29F1 and misfire faults, customer symptoms, possible causes and a staged low/high-pressure fuel-system diagnostic procedure.

The software-version references in this historical bulletin are period-specific. WrenchGuide uses the diagnostic relationships, thresholds and test logic only for the listed N54 vehicle scope and does not recommend obsolete programming levels.

BMW N54 diagnostic decision tree covering low- and high-pressure fuel faults, pressure sensors, fuel-pump plausibility, control-valve faults, long-crank complaints and related test branches.

Supplement to ISTA test plans. Use the decision branches as source-backed investigation guidance, not as proof that a named component is defective.

BMW bulletin covering 2A82/2A87 VANOS faults on N51/N52-family/N54 E-series vehicles, including secondary boost faults, oil-supply causes, solenoid/electrical checks and camshaft-bearing-ledge wear guidance.

BMW explicitly identifies 3100/120408 as consequential faults that can accompany VANOS faults on N54 and cautions against replacing unworn bearing ledges or camshafts.

BMW bulletin listing E-series VANOS and camshaft-position DME fault descriptions for affected E90/E91/E92/E93 vehicles, along with the documented rattling/power-loss complaint pattern and VANOS gear-bolt failure context.

October 2014 revision. E90/E91/E92/E93 are listed with production coverage from 09/2009 to 04/2012; the bulletin subject names N51/N52K/N52T/N55. Its six-digit 130xxx/164xxx fault-code group is separately scoped to F07/F10/F12/F13/F25 and must not be treated as E9x applicability merely because the same bulletin contains E-series codes.

BMW TechInfo Service Roundtable material documenting N52/N52K cold-climate crankcase-ventilation moisture/freezing, throttle obstruction and DME faults 2D09, 2CED and 2CEC, including inspection and conditional throttle-replacement guidance.

Use only for the documented N52/N52K low-ambient-temperature scenario. BMW states that moisture in the oil separator/hoses can freeze, that ice can obstruct the throttle while the vehicle is stationary, and that throttle replacement in this path is conditional on actual corrosion. NHTSA communication metadata independently indexes SI B12 01 08 / communication 10025573 for the same N52 EDK fault trio on E90/E91 and E60/E61 vehicles produced up to 11/2005.

BMW technical service bulletin for N55 fault codes 28A0 and 101F01, including post-programming/battery-reset adaptation handling and a staged diagnostic path for crankcase-pressure, induction and crankcase-ventilation leaks.

June 2019 BMW bulletin. It applies to the listed N55 models including E90/E92/E93. BMW distinguishes faults that appear after programming or battery reset from customer-complaint faults, requires adaptation first in the former case, and explicitly says not to replace the DME. Use the source's staged diagnostic logic rather than treating either code as a throttle-body parts order.

BMW technical service bulletin for N51/N52/N52K/N52T eccentric-shaft sensor plausibility faults 2A37 and 2A47, documenting rough-running/no-start/CEL complaints and an oil-contamination inspection path from the VVT sensor connector to the DME harness connector.

May 2016 BMW bulletin. It lists E90/E91/E92/E93 among the affected N51/N52-family vehicles. The source makes its parts-replacement branches conditional on confirmed oil contamination: no oil at the VVT connector means the bulletin does not apply and the applicable ISTA test plan should be followed. Code 134E08 in the same bulletin is explicitly F10/F25 only and is not E9x applicability.

BMW technical service bulletin for reproducible N54 cold-start rough running with DME misfire faults including 29C0, 29CC, 29CF and 29D0-29D2, documenting the wet-plug/carbon-deposit inspection context and a possible high-pressure-injector leakage or spray-pattern cause.

February 2013 revision. The listed vehicle scope is E82/E88/E89/E90/E92/E93/E60/E61 with N54 produced up to 09/2008. WrenchGuide uses this bulletin only for the documented reproducible cold-start complaint path; it does not generalise injector replacement to every occurrence of these misfire codes or to later production without separate evidence.

BMW service information for EGS fault 4F81 (ratio monitoring, clutch A), sometimes accompanied by 507B/507C/507D, with an E9x ZF 6HP diagnostic path that checks fluid level before inspecting the Mechatronic adapter seal.

October 2010 revision. For E90/E91/E92/E93, BMW limits the bulletin to N52K or N54 vehicles with ZF 6HP19TU (6HP21) or 6HP19X TU from SOP through 02/2008. The 507B/507C/507D faults are described as subsequent faults that can accompany 4F81 in this condition; do not treat them as standalone proof of a parking-gear component failure.

BMW technical service bulletin for E90/E91 MRS5 fault 93EB with the red airbag warning lamp illuminated, including the exact production-date range and a harness-first diagnostic branch before MRS replacement.

January 2016 revision, superseding the June 2008 revision. BMW limits the E90/E91 93EB bulletin to vehicles produced between 2005-08-31 and 2006-04-26. The procedure checks the TCU-to-MRS harness for open/short faults first; repair the circuit when faulty, otherwise replace MRS. The bulletin does not supply a stop-driving classification, so WrenchGuide does not invent one.

BMW technical service bulletin for diesel-particulate-filter regeneration, including E90 335d/M57Y fault codes 480A and 481A, their progression, pre-regeneration checks and documented temperature conditions.

February 2017 revision. BMW assigns 480A/481A to the M57Y engine used by the in-scope E90 335d and separately assigns 245700/245800 to N47T/N57T. Forced regeneration is only enabled when the relevant DPF faults are currently not present and BMW's documented temperature/fuel/fault-memory conditions are satisfied.

BMW technical service bulletin for soot-clogged diesel particulate filters when regeneration cannot be initiated, including the E90 335d/M57Y 480A/481A diagnostic branch and prerequisite root-cause checks.

February 2017 bulletin. BMW explicitly states that increased DPF loading is an effect rather than a root cause and requires relevant air/fuel/cooling/EGR/boost/vacuum issues to be eliminated first. Chemical cleaning is a later branch for soot loading and BMW warns it may only be performed once because repeated cleaning can damage the filter ceramics.

BMW technical service bulletin for E90/E92/E93 M3 vehicles with the S65 engine and DME fault 2AF9, documenting emergency-program, performance and rough-idle complaints plus the sensor/connector cause and BMW correction path.

April 2012 BMW bulletin. The source limits this repair path to E90/E92/E93 M3 with S65. BMW lists either an internal coolant-temperature-sensor fault or a sporadic connector problem caused by vibration-induced movement, and its correction pairs sensor replacement with the specified harness repair kit.

BMW technical service bulletin for N55 vehicles including E90/E92/E93 with SES illumination and reduced power / engine failsafe mode when DME fault 2C57 or 120308 is stored for boost-pressure-control plausibility too low. The bulletin provides a staged induction/vacuum troubleshooting path and explicitly warns against replacing the turbochargers from this fault path alone.

March 2013 revision superseding the August 2011 bulletin. BMW instructs technicians to diagnose other stored DME faults first, then use the applicable boost-fault test plan and inspect induction/vacuum-control causes if needed. The bulletin references a separate B121611_N55_Vacuum_Values attachment; WrenchGuide does not publish any numeric vacuum target until that attachment is separately reviewed.

BMW technical service bulletin for E90 335d vehicles with the M57Y engine and a documented DDE fault-code profile including 3FF1 plus cylinder rough-controller faults 4595/459B/4592/4596/4593/459C, where BMW attributes the profile to excessive intake-system carbon buildup and specifies an intake-cleaning and post-repair adaptation path.

November 2014 BMW revision, superseding the April 2014 bulletin. The carbon conclusion is source-bounded to the documented E90 335d/M57Y complaint and fault-code profile; it is not a generic interpretation of any one code in isolation. BMW directs intake-valve/manifold cleaning, requires DDE injector zero-mass adaptations to be cleared before the post-repair drive, and states that intake-manifold replacement is normally unnecessary unless required for another reason.

BMW service information for E90 335d/M57Y vehicles where injector zero-mass adaptation faults 4AD5/4AD6, 4AE5/4AE6, 4AF5/4AF6, 4B05/4B06, 4B15/4B16 or 4B25/4B26 are stored after intake carbon cleaning or extensive engine repair. BMW identifies incorrect DDE zero-mass-adaptation calibration and explicitly instructs technicians not to replace fuel injectors in this bulletin scenario.

January 2015 revision superseding the October 2014 bulletin. The diagnosis is source-bounded to the documented post-carbon-cleaning or extensive-engine-repair condition. BMW's repair concept is programming followed by clearing the DDE crankshaft increment-wheel adaptation with approved battery support. Historical ISTA/P, ISTA Next and integration-level version targets in the 2015 bulletin are not presented as current repair instructions.

BMW technical service bulletin for EML/reduced-power or flashing MIL complaints caused by throttle-valve sensor sensitivity during adaptation on listed N20/N26/N55/N63T/S63T vehicles produced from 2013-03-13 through 2013-04-18. It separates BN2000 codes used by E82/E84/E88/E89/E92/E93 from the later BN2020 code family.

May 2013 BMW bulletin. The bulletin's software-version and interim throttle-valve-replacement instructions are historical service actions tied to its release date. WrenchGuide preserves the source diagnosis and production boundary but does not present the old ISTA/P release numbers or interim replacement step as current repair instructions.

BMW service information for E90/E91 N52 vehicles with DME fault 2EF4 (Thermostat Map Cooling), including the insufficient-heating complaint, radiator temperature-delta check and the affected early BEHR thermostat production-date branch.

October 2009 revision. BMW limits the E90/E91 N52 path to vehicles produced through 03/2006. The E90 branch first compares engine-coolant and radiator-outlet temperatures after warm-up/idle; a delta below 20 °C follows the radiator branch, while a delta above 20 °C leads to the thermostat production-date check. The affected BEHR thermostat branch is limited to parts produced before 2005-11-25. The NHTSA bulk summary for SIB-12-07-06 contains a 23F4 token, but the underlying BMW bulletin identifies the DME fault as 2EF4; WrenchGuide therefore publishes 2EF4 and treats 23F4 as a source-bound mining false positive unless separate evidence appears.

BMW service information for E90/E91/E92/E93 vehicles from start of production through 09/2007 where the brake-pad indicator can illuminate even though pad replacement is not necessary and DSC faults 5DE0 and/or 5DE1 may be stored. BMW identifies a DSC software error and provides a CBS/test-plan/programming decision path.

May 2013 revision superseding the February 2013 bulletin. BMW limits this path to E9x vehicles through 09/2007, states the cause is a DSC software error, directs a vehicle test and DSC test plan, and says CBS data in the nominal range of 100% or less follows the complete test plan while clearly erroneous data such as 255% leads to programming. The old ISTA/P target is historical; WrenchGuide does not present it as current tooling guidance and does not infer pad thickness or wear-sensor resistance values from this bulletin.

BMW-hosted genuine-parts fitment page for part 11 42 7 508 970 with chassis, model, engine, production code and date-range applicability.

BMW's fitment table includes E91 LCI 320i N43 production codes US91 and US92 through 2010-02. Model/build-range fitment is stronger than engine-family evidence but is still not VIN confirmation for a specific vehicle.

BMW-hosted genuine-parts fitment page for engine oil filter profile gasket 11 42 7 508 971 with chassis, model, engine, production code and date ranges.

BMW's fitment table explicitly includes E91 LCI 320i N43 US91 (2007-07 to 2010-02) and US92 (2008-06 to 2010-02). Final user-vehicle compatibility still requires VIN/build confirmation.

BMW's fitment table includes E91 LCI 320i N43 US91 and US92 through 2010-02. Treat as model/build-range evidence until the active Garage VIN/build is checked.

BMW-hosted genuine-parts fitment page for cylinder-head-cover profile gasket 11 12 7 555 738 with exact E9x/N43 applicability rows.

BMW's fitment table includes E91 LCI 320i N43 US91 (2007-07 to 2010-02) and US92 (2008-06 to 2010-02). This is not by itself proof for a specific VIN.

BMW genuine-parts shop guidance explaining that compatibility can vary by trim/engine and instructing customers to provide the VIN for final confirmation on vehicle-specific items.

This source defines WrenchGuide's purchasing boundary: a model/engine/build-range match is useful evidence, but final one-click confidence for a user's car should require VIN-confirmed compatibility when the part is vehicle-specific.

Professional service-information reproduction of BMW SI B65 21 08 for E93 vehicles with an illuminated airbag warning lamp and ACSM2 fault 9402, identifying the Roll-Over Controller (ROC) as the component addressed by the bulletin and referencing BMW Repair Instruction RA 65 77 770 for replacement.

November 2008 BMW bulletin reproduced by Operation CHARM. The bulletin itself specifies E93 (3 Series Convertible), fault 9402 stored in ACSM2, a faulty ROC as the cause and ROC replacement via BMW Repair Instruction RA 65 77 770. WrenchGuide uses this as professional evidence and intentionally does not reproduce the safety-system replacement procedure or invent a driveability classification.

Current N43-specific Elring engine flyer covering gasket and sealing products with BMW OE cross-references, dimensions/materials for selected seals, and N43 architecture context.

Engine flyer dated 03/2026. Strong current professional evidence for N43 sealing-part cross-references, but an engine-family flyer does not prove every listed item applies to every N43 vehicle/build. Purchase-critical fitment must still be checked against exact BMW ETK/AOS/VIN applicability.

Official Elring technical guidance on cylinder-head bolts, clamping force and why Elring generally recommends new bolts with a new cylinder-head gasket.

General Elring guidance, not an N43-specific BMW replacement rule. Elring itself notes that some manufacturers permit bolt reuse under defined conditions. WrenchGuide must therefore obtain the exact BMW N43 fastener rule before marking head bolts as mandatory replacement parts.

Publicly accessible historical BMW TIS index for the E91 320i Touring with N43, spanning service information, repair instructions, technical data, tightening torques, operating fluids and special tools across the vehicle.

High-value historical research map for the exact pilot platform. Individual mirrored TIS pages commonly identify BMW AG - TIS and an issue status; applicability and revision status must be captured per cited page. Historical mirror evidence does not replace current BMW AOS/AIR or licensed professional confirmation for safety-critical values.

Historical BMW TIS repair instruction for removing/installing the N43 engine on the E91 320i Touring, including prerequisite jobs and BMW special-tool reference 11 0 070.

The mirrored 11 00 050 page identifies BMW AG - TIS, issue status 12/2007. It explicitly lists transmission removal among the preliminary tasks before engine extraction. Treat this as strong historical corroboration of the BMW removal route, not current safety-critical authority until checked against current BMW/professional data.

Historical BMW TIS N43 intake-manifold procedure with prerequisite jobs, connector/vent routing details and tightening-table references.

Useful for decomposing the engine-removal prerequisite graph. Issue status shown by the mirror is 12/2007; current procedure/specification checks remain required.

Historical E91 320i N43 manual-transmission procedure for the GS6-17BG, including propeller-shaft separation, transmission support and BMW special-tool references.

The exact E91 N43 page identifies the GS6-17BG procedure and historical BMW support tools 23 4 050, 23 0 132 and 00 2 030. The same N43 procedure family is identified as 23 00 017 on other E9x N43 variants. Current applicability, fluid and tightening data still require current BMW/professional confirmation.

Historical N43 drive-belt procedure documenting the spring-loaded tensioner, special tool 11 3 340 and belt inspection/reuse notes.

N43 procedure 11 28 010 is shared across multiple E9x N43 applications. The exact E91 320i full index also lists this N43 procedure; current tool/procedure applicability should still be checked before executable guidance is promoted.

Historical E91 320i N43 cooling-system venting and leak-check procedure, used as a dependency target after coolant-system work.

Historical document 17 00 039 is useful for mapping the cooling-system validation phase, but the mirror is issue status 12/2007. Coolant specification, fill quantity and exact current venting procedure must be checked against current BMW/professional information before publication as actionable guidance.

Historical E91 320i N43 exhaust-manifold procedure exposing dependencies on the exhaust system, right engine support arm and expansion tank.

Historical procedure 11 62 000 helps connect exhaust work to the engine-support-arm dependency. Replacement-hardware, paste, seal and torque instructions remain subject to current BMW/professional verification.

Historical E91 320i N43 catalytic-converter procedure with dependencies on the complete exhaust system and right engine support arm.

Historical procedure 18 40 040 is relevant to the exhaust/support-arm dependency graph. Scalding warnings, hardware replacement and tightening data must be revalidated before use in current executable guidance.

Historical BMW TIS multi-page N43 timing-chain procedure covering the chain, guide, slide rail and clamping rail relationship and the associated timing workflow.

The linked page is within the multi-page historical TIS procedure and identifies BMW AG - TIS issue status 12/2007. Cross-check the complete current procedure, special tools, one-time-use hardware and tightening data before executable guidance is promoted.

Historical BMW TIS fuel-injector procedure for N43 direct injection, including special tools, pressure hazards, PTFE/decoupling-element replacement notes and injector adjustment requirements.

Document 13 53 310 is a strong historical N43 source but involves high-pressure fuel hazards. No depressurisation, seal, tightening or injector-adjustment instruction should be promoted as current safety guidance from this mirror alone; confirm against current BMW/professional data.

Publicly accessible mirror of a legacy BMW AG TIS tightening-torque page for the N43 cylinder head, including separate fastener groups and torque-angle stages.

The mirrored page identifies its source as BMW AG - TIS and shows issue status 12/2007 with a warning that it is valid only until the next DVD is issued. Useful for corroboration and source tracing, but not sufficient alone for WrenchGuide's verified badge or a current safety-critical value.

Historical E91 320i N43 engine-mount procedure that explicitly requires the engine to be secured in installation position and points to tightening-table reference 22 11 1AZ.

Historical issue status 12/2007. Strong evidence that engine support is a prerequisite around mount work, but the mirror does not verify a current DIY lifting/support method or current torque/replacement rules.

Historical E91 N43/N53 transmission-mounting cross-member procedure requiring transmission support before cross-member removal.

Historical issue status 12/2007. Useful for proving the transmission-support dependency; current support equipment equivalence and tightening data remain blocked pending current/professional evidence.

Historical E91 battery distribution-box procedure with an explicit prerequisite to disconnect the battery negative lead.

Historical issue status 12/2007. This helps map electrical-isolation prerequisites but does not replace current BMW battery/IBS handling guidance.

Historical N43 coolant-pump procedure that references cooling-system venting after installation and exposes the pump tightening-table locator.

Historical issue status 12/2007. Useful for the cooling dependency graph; coolant specification, exact current venting procedure and tightening values remain separate verification targets.

Historical N43 thermostat procedure documenting a cold-engine/scalding warning, coolant drain/fill dependency and post-install leak-check relationship.

Historical issue status 12/2007. Hazard/dependency mapping is useful, but current coolant specification, disposal requirements, hose/fastener values and venting instructions must be verified separately.

Historical N43 flywheel procedure containing a manual-transmission-specific installation relationship and adapter-sleeve orientation note.

Historical issue status 12/2007. The source is valuable for relationship mapping, but flywheel fastener replacement rules, tightening sequence and clutch-related specifications remain safety-critical verification targets.

Historical BMW TIS technical-data page for E90/E91/E92/E93 N43 cooling systems, including transmission/A-C-specific coolant-volume data and cooling-system test pressure.

Historical issue status 12/2007. The table lists 8.4 L for N43 vehicles with integrated A/C and manual transmission and 9.2 L with automatic transmission. Treat those values as historical corroboration until current BMW/professional data confirms exact build applicability.

Historical N43 cooling-system venting and leak-check procedure, including expansion-tank and oil-water-heat-exchanger vent points and the electric-pump venting cycle relationship.

Historical issue status 12/2007. Useful for source mapping and corroborating the N43 venting workflow; do not release the historical sequence as current workshop instruction until current BMW/professional procedure and coolant specification are reviewed.

Historical E91 N43 cooling-system pressure/leak-test procedure with special-tool references and acceptance criteria.

Historical issue status 12/2007. The page exposes a historical test method and acceptance figures; all pressure values remain historical corroboration until current BMW/professional data is reviewed.

Historical E91 320i N43 engine-oil service procedure documenting filter-element/O-ring replacement, drain-plug sealing-ring replacement and electronic oil-level checking relationships.

Historical issue status 12/2007. Strong historical evidence that service replaces the filter O-rings and drain-plug sealing ring. Oil specification, exact fill quantity and tightening values remain separate current-verification targets.

Historical N43 full-flow oil-filter procedure that maps coolant drain, intake-filter-housing removal, alternator protection and special tool 11 9 240.

Historical issue status 12/2007. Useful for mapping a deeper oil-filter-housing job, which is distinct from a routine filter-element service. Current seals, tools and tightening data still require verification.

Historical N43 oil-sump procedure mapping engine support, front-axle lowering, oil-level-sensor disconnection and the requirement to respect exact engine-oil filling capacity.

Historical issue status 12/2007. The page explicitly warns that overfilling can damage the engine and that exact filling capacity matters; the actual current fill value remains blocked until separately sourced.

Public BMW parts-catalogue mirror for E91 320i Touring N43 applications, exposing model/engine applicability, exploded groups and BMW part-number references.

Very useful for research and exploded-part relationships. Part numbers can supersede and production month/options matter; verify current part numbers through BMW ETK/AOS or an authorised/credible live catalogue before presenting purchase-critical fitment as verified.

Specialist BMW N43/N53 diagnostic material covering INPA/MSD80 data interpretation and practical fault-analysis workflows.

Useful practical specialist context and a source of research leads. It cannot establish verified safety-critical repair specifications by itself; cross-check claims against BMW/professional sources.

Open-source .NET EDIABAS-compatible interpreter and Android Deep OBD application with BMW D-CAN, K-Line and E-series diagnostic support.

A legitimate open-source diagnostic stack. It can complement official BMW tooling without distributing BMW proprietary applications.
