Hi I have a audi80 tdi 1900cc 150.000 miles

I wonder if you have ever experienced the problem i have with mine.
It judders and shakes alot at around 2000 revs, regardless of gear. I have to drop the gear and raise the revs & push through it before i can get back into the higher gear.

have you got any ideas, I replaced the mas air sensor, but still have problem .

would be very grateful if you can help

cheers
Nick
