Hello to everyone,i am new at this forum it is great to meet you all hope you guys have somme advices for me regarding my problem.
I have an Audi 2.0 TDI 2007 100 KW,190.000 kms my problem appeared recently,every time i start the car and the engine is cold the car runs ok during 5-7 min and then between 1400-1800 Rpm it starts to shudder,shakes and the Rpm is fluctuating while accelerating.
If i accelerate over 2000 Rpm the car runs normal,all these problems stop when the engine reaches the normal temperature,and then if the car is parked a couple of hours and the engine is cold,all the problems reappear again until the normal temp.
Also noticed lately when i accelerate first gear a have sometimes a lack of power and a wired noise is coming from behind (like a suction struggle i think or like a vacuum struggle -maybe my fuel pump?)

I have cleaned the MAF with MAF Cleaner,replaced the coolant temperature sensor,engine treatment.
The car was scanned with Ross Tech tool no problems detected,injectors looks good,etc.
Can you help me with some advices please.
Many thanks to you all

 

Nobody?????

 

Unfortunately, most people on this forum are in the US and that engine was never imported here. We are also not very familiar with Diesels.

 

Thank you for your answer. It just make sense,i will take this to an european forum then.

Take care.
