    So yesterday i got 16487 and 17704 trouble codes , i found some info too, first one is MAF sensor with/or possible boost leak and the other one is temp sensor or thermostat, goes into limp mode after hard acceleration and stays at 5psi, in a minute or so goes back to normal, and starts vibrating while at 16psi and up, anyone had those codes and those symptoms? please feel free to help a braza out:) thanx. andrey.

    Do you have the updated green coolant temp sensor? If not, and yours is black, replace it. The vibration you feel is probably a misfire. Are you able to scan with VAG-COM?

    Does your CEL illuminate when you turn the key one before starting the car? If not, it's probably burnt out. Have you scanned for codes?

    I was worried that the light was removed before I bought the car but it does light up when I turn the key. Scanned it and was reading left bank egt bad. $800 dollars later at a so called audi guru the car acts the same. Weird thing is it only runs like this during the winter months.

    Scan the car for codes and post them here. If you don't know someone local with VAG COM then you can get by using a generic scanner from an auto parts store, but the codes will be generic and less specific.
