Ask the GIAC place that flashed it?

 

my apols there P1556 is indeed the turbo must have been looking at something else[8D] but old crazy sussed it

 

you may be overboosting. i had that problem. try disconnecting the battery for a while and then reconnecting. then give the car time to adapt. dont try pushing it or the ECu will throw the overboost code. thats what i did and after two weeks of babying it my car was fine. do you have cel?

 

it might be worth testing the wastegate valve if you cant find any leaks

well I am not good with messin with cars so I regret to inform you guys that I am taking it to the stealership today to correct whatever is wrong.[:'(] Anyway thanksfor all the hel and I'll let you guys know the cause of the problem when I findot what it is.

 

the culprit the air pump according to AUDI. The airpump and o2 sensors came up when he cleared the code only the airpump came back. he says $420 for the part + install on top of the $120 for doagnosis of the problem. Is the airpump worth changing, he says the stock one may be fine but it is throwing a cade and will need additional testing. All I heard was $$$$$$$$$$$$$$ CHA-CHING$$$$$$$$$$$$ BEND OVER $$$$$$$$$$$$$$ Any opinions ona possible alternative??

 

Bring your own KY to save a few bucks?

Or replace it yourself.

 

change the fuse and relay to be found under the hood
