I'm after a bit of help!?
I've had the traction light on for ages on my S3 2001 facelift. Took it to a specialist who said the longitudinal sensor needs replacing. He replaced it but the light is still there. He is now saying that it looks like a signal problem from the YAW sensor. There's no way I want to spend £500 on this sensor so i'm thinking of getting a second hand one. Does any one know the part number for the YAW please? I know the longitudinal sensor sits on top/front of the YAW.
Also is this a sensor which you can replace yourself? Does is need calibrating? Is it located under the steering column?
Any help would be much appreciated
