Hi
First of all apologies if i am posting this thread at the wrong place as i am a new member to this forum. I have a problem that is going on for a while.

I have a 2007 audi a6 2.0 TDI. Recently i noticed limping when going above 60mph or uphill. The vehicle runs completely fine at low speeds and downhill. I did take it to different garages but i am getting different opinions and i am a bit unsure. Hope you guys could help me out.

Thanks.
