wonder if anyone can help. got an a4 avant 1.9 tdi 115 bhp y reg. going uphill when car has to pull i lose all turbo power until i stop switch off the engine and then it resets itself and off i go till another hill. had a new turbo and the maf is ok. so far from reading other threads it might be a case of cleaning a few parts eg egr/ n75 valve etc could anypone point me in the right direction of these parts so i can do it. also the car smokes quite a bit when being driven under load, black smoke.
don't know whether it was just coincidence but when i started losing turbo power the air bag light came on , just seemed strange that it went at same time!!!!!!!
hope someone can help as don't really want to go to garage!!!
it was put on the vag-com software and came up with this negative deviation!!!:confused:

fault found to be split in turbo outlet pipe, pressure side.
