Hope all is well , my check engine light keeps illuminating after the dealers states that the problem is cured. dealer is stating that the O2 sensor is the problem and replace the vac lines, but the check light appears.

please advise

Does your dealer have a VAG fault code reader?Ask to see the readout so you know exactly what the problem is.If they dont have one,go to a dealer that does!
If the O2 sensor is faulty,replacing vac lines wont help! The O2 sensor has a heater element in it,this may be O/C,or the sensor itself may have failed.Anyway,reading the failt codes should show what the problem is.

Forgot to mention the car is a 03 RS6.....the C/E light came back on and the car is back to the dealer....dealer: replace vac lines(crack), changed the air canister(crack), but still getting the c/e light. dealer is still wondering what the problem could be and decided to call a master tech....no dice. any thoughts? the other forums are for kids and smart ass remarks i can live w/out...
