Hi everybody, I got audi a6 1.8T auto, T - reg., I got problem for few weeks, my car hesitated under acceleration, I replace turbo for new one, new Lambda sensor, MAF sensor, DV valve - miltek , clean throttle body, replace all vacuum pipe, check everything for leaks,everything is just fine, but car still hesitated, I don't know what can I do, I find here on forum, maybe can be EGR, but I don't know if I got one, can anybody help, or where can I find, if got my car one or not??? Thank you very much for any help..., or advice..., thanks...

No problem mate, still thanks for respond, now I got on my vag com 17963 code, I start thinking about my chip maybe is faulty, I chipped my car nearly half year ago, everything was just fine, but last 2 months I gopt hesitation, I checked error codes was clear - no faults, I replace turbo for new one, new lambda, DV, MAF, Throttle, still hesitation, I now my vag com start showing 17963, and looks like car got more boost as it's needs...., , then I keep looking what can be wrong, I love my car, I will do everything , will be ok again..., and few options left : egr, upgrade chip, ecu, etc. ...

Thank you very much for your help, just 2 days ago, I find, inside the one of the pipe N75 was very small piece of rubber, and that make all trouble - hesitation, surging, loosing power .., now I replace my N75 F valve with N75J valve, and its much much better , no any trouble at all, thank again for your help...
