Been battling this driveability problem for a month now, I travel for work so it makes it virtually impossible to deal with issues at times.....I had this car in to three different shops in the past month, they all said they couldnt find the problem after days of checks and rechecks, yesterday I got outta work early and decided to **** around with the car see if I could get lucky. Well, as luck would have it, a Charge Pressure Control Positive Dexiation code can be set from the throttle body boot being torn on the bottom, I am new to audi, but not to troubleshooting driveability probs on autos, KEEP IT SIMPLE its only nuts and bolts. ECS tuning is hooking me up with there improved version of the part.
