Practical guidance on diagnostics and maintenance helps you start with the right service.
How to recognise turbocharger problems, what to safely check yourself and what to expect during professional diagnostics. When to stop driving and go to the workshop.
The check engine light comes on right after refuelling. Most often this is an EVAP system issue, but there can be several causes. We explain possible reasons, what you can safely check yourself and how professional diagnostics proceed.
After an ECU update new error codes, loss of functions or communication issues can appear. This article explains typical symptoms, possible causes, what to check before a garage visit and how professional diagnostics proceed.
