It has a tiptronick transmition which had an oil change 10.000 miles ago. It did feel a bit smoother just after the oil change. I have had the car two years now and it has always judderd. I wonder if the transmition oil is a bit low.

Re: Audi A4 2.5 TDI Juddering when pulling away.
Get it plugged into diagnostic equipment that way you can see what clutches are being used and what power is being used by the solenoids if the oil was low it would have run hot and that is not good news for auto boxes

The best oil for Audi 1.9 TDI is CASTROL 0W30 SLX Longlife II (TDI Pump Nozzle) VW Norm 506.01 . This oil is issued by Castrol special for TDI - Pumpe Duse (Pump Nozzle) engine as longlife oil (50,000 km service interval, or two years). Also a normal service oil (15,000 kmservice interval, or one year) is Castrol TXT 5W40, and Castrol EDGE 5W30, for TDI Pump Nozzle engines, VW Norm 505.01.
new synthetic oils have lost a chemical in past couple of years to save on $ I use a brand called ams oil 5w30 along with a lucus oil additive and a hastings oil filter. have over 218000 hard miles and still going. proof is in the pudding.
These cars Have a fault with the Crankshaft damper breaking up.This is all fitted in the bottom crank pullyRemove the bottom pully and check.I think you will find that damaged.I have had this problem before on audi vw seat.
Check the gearbox oil - has this been changed (with the wrong grade) just before the problem started ? May also be too little oil, from a small leak - which will get very thin when then inevitably overheating. Best to change the gearbox oil, note if lots of sludge or debris comes out (or is attached to the drain plug). If oil is the problem, total siezure may be just down the road.
tandard practice to change the oil on a clutch replacement. Was the replacemmiles it's covered, but it's not sounds like the gearbox oil need changing. You don't say how many miles it has done. Gear box oil is not usually changed in a clutch replacement. Did an Audi garage carry out the rlacement? It could be the cable needs adjusting to allow the clutch to have free movement
