Diagnose smarter. Fix faster.
FaultNet is a collaborative platform that lets you document, track and solve vehicle faults solo or as part of the community.
Got a warning light on the dash? A noise you can't pin down? A fault code the garage charges £90 to look at? FaultNet gives you the tools to document what's going on and dig into the data and find out what others with the same car or other cars with the same fault have experienced.
Your garage
Add your vehicles and keep all their fault history in one place. Add photos to your vehicles, create a gallery and send it to your mates.
Fault cases
Create a case for any fault. Add DTC codes, photos, videos, timeline notes — build up a complete picture of what's happening.
Community search
Search thousands of fault cases by make, model, DTC code, system or conditions. Find what worked for others.
