The engine management light has come on my Q7.
its been taken to an Audi main dealer , after diagnostics it was established that the "break switch" needs to be replaced , a part the costs about £10.00
After this was replaced , the car was started but the engine management light is still ON ,but when hooked up to the diagnostic machine no fault code has been stored.
Any ideas how the management light can still be on , but no fault stored on the cars computer ?
thanks in advance
(will post this in other sections- so every body see this post in case a common problem)
