Hey Guys,

I have a 2002 Audi A4 1.9tdi. Since Monday I've been having a strange problem with the car when I accelerate. Basically, if u accelerate very lightly there is no problem but if you go to accelerate not exactly hard but enough to build speed the car starts to shudder and jump. There was no sign of a problem gradually happening it just started all of a sudden, I only noticed it when I went to overtake and it's started shuddering with reduced power.

To describe it, when u start to accelerate it kind of feels like the wheels are spinning as if on snow but your driving at speed. if that makes sense?

I tried the mass air flow on the turbo but that doesn't seem to be the problem as it was still happening after putting the new maf in. I don't think it's the clutch as the typical clutch slipping signs of the revs increasing on the clock when u accelerate is not happening. Checked the wishbones, all the pipes around the turbo and engine mounts too and no sign of a prob!

I've no warning lights coming on so don't know will it throw any codes but I'll get it on a computer tomorrow and see if anything shows up.

This has me a bit baffled and worried. I Would greatly appreciate if anyone has any ideas or had any similar problems.

Thanks a lot!
