got this today....

17965 - Charge Pressure Control: Positive Deviation.

35-10 - - - Intermittent.

what could be the culprit? We replaced the pressure line to the 710 and the smaller one doesnt seem to be leaking...wastegate on diagnostic seems to cycle normally as on another a4...(not ruling out the n75 tho) any thoughts/ideas? id like to to as much diagnostic work as possible to avoid making the dealer search for the problem. (my car is under warranty but i cant really leave it at the dealer overnight or for a week or so as its the only box i got...)

I have a custom chip but the tuner is not sure how to tackle the problem. Is it the wastegate or the BOV or is it over boost???
HELP! I hate limp mode with 5psi boost!

its supposedly overboost...but Ill know whats up later this week with the turbo/wastegate. a GIAC chip should not send it into "limp mode"...
