hi my audi 2006 A3 2.0tdi sport, when getting to around the speed of 80 mph the car is loosing power and goes into idle mode with the engine management light on, when turning off the ignition and switching back on this cures the problem until i get back upto around the speed mentioned earlier in this thread, i have put it on a diagnostic machine & error code p2034 is coming up which says the turbo is over or under power etc!! i have tried the cheaper option of replacing the thrust control sensor which hasn't cured the problem and now i have bought a new turbo for the car!!!! i was told by a specialist that by buying the new turbo should 99% possibility of sorting this problem out!! Before i replace the turbo i want to check with other people's opinions i am doing the rite thing??

Please can i have as many replies as possible to what you think?

Regards

Mark
