Hi

Has anyone experienced any problems with there B6 A4 - today I noticed my ABS and ESP light come on when the engine fan comes on.
When I turn off the car and re-start it, it disappears then it comes back on when the engine fan cuts in.... obviously something not quite right ... wondered if anyone out there has experienced a similar problem.

Appreicate any responses

Best to take to dealer to diagnose with VAG tool and there maybe other errors logged as well.
which may lead to the cause.

Thanks Mate,
I took the car to Audi Centre (Melb) and they said to me that the sensors are buggered - ie the engine fan sensor and the ABS sensor, and why the ESP light comes on is a bit of a mis-noma to them. Audi Centre Melbourne were fantastic they really spent time on the car a and said that the replacements would be all covered under waranty... Thank god for that !!
I might consider chipping my A4 in the coming months - but is it really worth it ... not sure

btw get a GIAC
