after a service at audi, the come up with these 2 faults,
my s3 seems to be running fine. they quoted me nearly £200 to fix the 2.
just wondered if anyone else has had these and if it needs doing

i would of though the brakelight sensor just tells me when my lights are out..
and my tempreture gauge works fine

and ideas please..
