b5 s4 stall and no start HELP!!
hello, im fairly new to the 2.7t engine, so hopefully some one can assist. i baught a 2000 audi s4 6spd not to long ago. i immediately upgraded the cat bak,intake,and suspention, along with the install of a boost gauge and turbo timer. car ran geat! now i have installed and GIAC chipped ecu. i baught the ecu off ebay, the ecu match my stock ecu exactly, the car ran amazing couldnt belive the power gain. a day later the car sputtered and then stalled on me wile i was driving. and then would not restart just kept turning over. first thing i did was put the stock ecu back in. now the car starts and runs fine! is this a common problem with chipped ecus? is this a fixable problem? thanx, justin

don't know what obd2 scanner you are using. does the scanner work with the good ecu?
what's the bosch number of that ecu? 0261-?

As mentioned and to know for sure, VAG needs to communicate with it in order to confirm.
Perhaps post a good pic of the circuit board and note any board numbers.
