my 07 2.0tdi 170 dsg shudders badly from cold starts in winter, new battery helped a bit, must check the glow plugs...
Hi there mungo, well the answer to your question is not really. Does yours do this when you're starting the car? mine seemed like it wasn't getting either enough fuel onough air. When I turn the key it goes a clank clank vroom & the engine shudders. It's not the mounts nor the flywheel (b-new) god knows what causes this? Could be ignition issues I just don't know. My car been into Audi 3 times & each time they haven't done **** about it, probs because they don't know how!I wrote to Audi in Germany & they said that they had not heard such findings before, so are unable to help. Yeh right!!!!!!
I did replace my battery & it has helped a lot, yet it's still there. Not as violent & not as much.
Is yours a 140 like mine, or 170?
Hi you guys, hope any of you can help me as I'm close to driving my A3 off a cliff!
I have a 2007 2.0 TDi Sportback 140bhp BKD engine. Not too long after owning the car which was bought April 2011, the engine developed a judder & rattle on startup just before it fires up. The car incidently drives flawlessly.
It was doing my head in so I took it into an Audi dealership after hearing horror stories that there were problems with certain injectors. They didn't tell me that only the 170's suffered from this oh - no!, yet they went ahead & did the diagnostic anyway costing me £107.50. Long story short, they said my EGR needed replacing. But on inspecting the printout it said no communication with EGR.
I was pointed in the direction of an Ex Audi mechanic who told me that the printout is wrong & the reason for the non comms of the EGR is because it is vacuum operated & not electronic like on some other models.Your EGR is fine he said.
Anyway, he turned the car over a few times & heard the rattle & felt the judder. He said it's your Dual mass flywheel, it's f**ked. So I got him to replace the flywheel & timing belt for me.
After a few start ups the fault started again! not so violent as before tho! I took it back to him & iterated that it was back. He said it could be the starter motor, on the 140's the armature windings can fail & give the starter motor a stop go - stop go type of rotation causing the starter to snatch at the flywheel. So I had him replace that also! When I had the car back he tested it over & over, in front of me & no judder.
Hoorah I hear you say!
Sadly no! The judder is still there, but only occasionally now & even less violent than the 2nd time. It really just does your head in!!!!
I'm £1070.00 to the bad & suicidal. Fair enough he came to my home with (Audi's own diagnostic laptop that he was loaned, sssh) he ran a diagnostic there and then. The only red flag was that my synphony stereo was not coded correctly, yet I've not had 1 problem with it Nothing, no faults at all!
I just do not know what to do now, I'm outa cash & outa ideas. What else can it be?
Please please can anybody help?
Definitely seem to be injector leaking.Exactly same here , same symptoms and everything only 1 extra , at idle i have a huge wiff of unburnt diesel :S
Hi mate what was the final conclusion on this as I have the same problem and even after changing the flywheel and clutch twice? Do you know the brand you used for the flywheel? ThanksHi you guys, hope any of you can help me as I'm close to driving my A3 off a cliff!

Hi mateMine turned out to be a flywheel issue. Had it changed under warranty and so far no judder through the gearbox hopefully its solved.
