Guidance is ranked against the car you are actually working on instead of assuming every variant is the same.
AUTOMOTIVE WORKSHOP COMPANION
Repair guidance built around the car in front of you.
WrenchGuide connects your vehicle, repair guides, parts and tools, reviewed technical information, progress and workshop notes so the whole job lives in one place.
BMW E9x is the first community focus. Coverage now spans multiple engines and drivetrains, and the platform remains vehicle-agnostic as reviewed guides, owner questions and technical coverage are added.

WHY WRENCHGUIDE
A repair manual tells you what. WrenchGuide helps you manage the whole job.
Repair information is scattered across manuals, forums, parts catalogues, diagnostic tools and personal notes. WrenchGuide turns that into a structured workshop flow without pretending uncertain information is fact.
Important specifications and repair facts show where they came from. Anything uncertain stays clearly marked.
Critical safety checks can block a step, and WrenchGuide will not guess missing safety-critical values.
Progress, notes, photos and essential repair data are designed to keep working when connectivity is poor.
BUILT BY PETROLHEADS, FOR PETROLHEADS
Useful repair knowledge should be easier to find, understand and trust.
WrenchGuide is a community-driven workshop companion. No paywalls around core repair knowledge, no sponsored answers — just better information for people who like working on their cars.
Repair knowledge should not disappear behind a paywall. The core guides, evidence and technical answers stay open to the community.
Owner questions, corrections, better sources, workshop photos and missing procedures help decide what WrenchGuide researches next.
Money, donations or future partnerships never get to change a technical answer. Evidence wins every time.
HELP BUILD WRENCHGUIDE
Found something wrong? Know a better source? Have repair photos or a missing procedure?
Tell us. WrenchGuide gets better when owners share what they have learned, and community questions help decide what gets researched next.
Community supported. WrenchGuide is currently a passion project. Optional ways to help with hosting, infrastructure or research costs may be added later, but core repair knowledge should not disappear behind a paywall and funding never gets to influence technical answers.
