Hi

I have an 05 2.0 tdi 140hp s line.

It has a slight hesitation when acceleration in 2nd gear. When floored it goes away, it only happens under mild/normal acceleration. It feels like it is stuttering/juddering. It does not happen all the time, maybe 1 in 7 times. It has started to do it in 1st and third gear the very very odd time.

Could this be a dirty maf sensor?

Any other ideas?

Thanks
