A steady warning light usually means the car has logged a fault that needs checking soon. A flashing engine light, or one that comes with limp mode, means you should stop and get it looked at before driving further.
ODIS is Volkswagen Group's own dealer diagnostic system, with guided fault finding and online coding. VCDS is a powerful independent tool for fault reading, live data and coding. We use both, depending on the job.
Yes. We use PIWIS for Porsche and ISTA for BMW, so we can read and clear manufacturer-level faults and carry out adaptations on those cars too.
No. Clearing a code without finding the cause only hides the problem. We diagnose the root cause, explain what we have found and quote for the repair before doing any work.
