Everything between a stubborn code and a finished repair
Built for the independent shop owner running their own show, not a dealer service department with a factory subscription already paid for.
Guided repair procedures
174,000 checkable steps across 69 chassis and 43 systems. Nearly every procedure is a yes/no decision tree with the measurement that confirms the cause, the usual root causes and the common misdiagnoses up front.
Electrical Guides
Component-by-component "do this / what you should see" walkthroughs for general electrical diagnosis, in their own tab.
Reference: 64,753 fault codes, torque & specs
Trouble codes cross-referenced by chassis and control unit, plus torque and spec tables, a component locator and labor times, each linked to the procedures that use them.
Shop Talk
Live channel-based chat for the whole shop, plus threaded forums for the stubborn cases that need a longer conversation.
Community fixes, moderated
Every fix a specialist submits is reviewed by an admin before it goes live.
Ask Eurofault
Describe the car and the problem in plain words. The assistant searches the database, names the likely cause, warns you what not to replace and links the procedures. Progress and favorites sync across every workstation.
From fault code to fix, without leaving the bay
Three moves between a stubborn code and a documented, checkable repair.
-
Search the code or symptom
Pull a DTC, describe the symptom, or jump straight to a chassis-specific system. Matching procedures surface instantly.
-
Work the guided steps
Each procedure is a flowchart you can work from the box you clicked, with the confirming measurement, wiring diagrams, torque specs and the field notes that never make the factory manual.
-
Ask Eurofault, ask the shop, or submit the fix
Stuck? Ask the assistant, or drop it in Shop Talk. Found something new? Submit it, report a wrong step, or add a tip, and an admin reviews it before it joins the database for everyone.
One search instead of three browser tabs.
The procedure, the wiring diagram and the shop conversation about it live in one place, searchable from any device on the floor, with no factory scan-tool subscription just to read a diagram.
We used to keep three browser tabs open just to confirm a SAM pinout. Now it's one search, and the fix from the last time someone on our team hit the same code is right there in the thread.
