Hi, i have a 2006 A3 2.0 (140) sportback. After recently having my major service done at dealers, i had the cambelt changed (bought parts from europarts) at local garage. The 1st time i took car, the car was juddering really badly in idle the there was NO turbo so having shown a few ppl with vw n audis, they all told me that he hasnt fitted the cambelt on and set the timings properly so i took the car back to the garage and asked him to sort it. This time the car was juddering less in idle the turbo was working again but it doesnt have the same kick as it did before the cambelt change and the juddering has not completely gone. I took it to an audi specialist and he has told me that my car is fine and that its normal for a tdi engine to judder when it approaches 100k (mine has done 99k) but my argument is that it didnt do it before the cambelt change and the turbo had more kick to it.

CAN ANYONE PLEASE GIVE ME SOME ADVICE AND HELP PLZ!!!!

regards

That "specialist" is talking through his hoop mate. Judder on idle and lack of performance after a timing belt change could be a number of things. A sensor may not have been reconnected. On these engines you also have to connect the car upto VCDS and electronically adjust the timing. There ecu has the ability to retard and advance the stroke based on the info it recieves. I'd take it back to the garage and say- if it's not PERFECT- as when I left it to you, then I will go to Audi and my solicitor will send you the dealerships bill for fixing your mess.

I did mate but there is so much that garage can do, it was still lumping in idle,they dont have the right equipment, they specialise in old toyota and honda, my fault for taking it there but he offered £100 for labour and that was brilliant compared to rest who quoted me £200, i guess you get what you pay for. Iv booked it in to a local specialist, Chris Umpleby, he said he will have to take the belt off and refit it again himself which is going to set me back another £160.

It could be so many things. I'd replace he engine temp sensor, and maybe clean out the egr? Check all vacuum pipes too as splits can cause all matter of problems

Did they change the water pump when they did the T belt? Because I'd say is more likely there's a leak raher than them not filling it up. Nope totally unrelated to the judder on idle.
