mechatronics???? causing juddering on pulling away

[Jacky Turner]

Sorry if I am in the wrong area of the forum but my problem is with an Audi A3 Auto 170 '57' plate 5 door auto 2'0 TDI 37'000miles. When I pull away from stop sometimes I get a judddering almost like I am in the wrong gear or fuel is not getting thro?
I have just had it serviced and the recall injectors replaced the Audi garage mentioned it may be The 'mechatronics?' as this is common but this would need to be investigated and replaced if need be does this sound familiar to anybody else or could the problem be something else?
Also if it is common why have they not been recalled and put right.

What sort of costs will I be looking at?
Update 16th Nov
I have had contact from garage who sold me and I have know quoted trades desc etc/they think it may be a clutch problem (in an auto???) which according to them considering age of the vehicle is probable and is my lookout or take it to my audi dealer to diagnose problem and if it is a parts malfunction then they are to contact the seller of the vehicle what are my chances and should I be paying for the diagnostic work as I have quoted sale of goods etc and is this mechatronic problem a parts malfunction please help???

Ok 1st of all, did you have the issue before the injector recall, as allot of people have had issues with the injector recall completed.

yes and the car does it less since injectors were done.

Then this would denote logically, its not mechatronics if injectors helped the problem.

Maf been checked, cambelt/timing out, could be variety of things before condemning gearbox, also if you want to check, get someone with vcds to do a gearbox reset so it relearns driving styles & see if this helps.
