hi ****
Is your car a diesel?
I drive a 1.9tdi and was juddering on acelleration. Problem was the fuel injection pump, changed out and is now ok.
hope this helps.

i have a 2000 1.9 tdi and had the same problem..

i started by having the airflow meter changed.. sorted nowt!
then i had 3 out of 4 glow plugs changed.. sorted nowt again!
finally i had the turbo changed.. sorted everything!

a pricey fix.. luckily my car was under warranty ;)

hope this helps without worrying anyone too much.. good luck

sorry i took a bit of time getting back to you fella..
the turbo cost £500 and was fitted by the place i bought the car from.. they paid for the whole thing!

i hope you get it sorted bud.. good luck ;)
