My check engine light comes on and off
I have an 09 VW CC Vr6 which i bought in March of 2016
and now my check engine light comes on and off every
couple days, so i took it took my mechanic, he ran the
diagnostic on it and 2 codes popped up, 1 for low air
pressure to the engine and the other was for the heated
seats, now he told to take it to the VW Dealership since i
have a bumper to bumper warranty, now i took it to the
dealership, and they ran their diagnostic on it and took 2
and a half hours tried charging me 90$ an hour( which they
didnt end up charging me) but they said there was nothing
wrong and turned the CE light off. Its been comming on and
off now for about a month and they dont want the codes
from my mechanic because they said their warranty
wouldnt cover an outside diagnostic. What should i do?
Does anyone have any idea what can be wrong? My car
runs fine there is no misses or sputters .
