Hi Guys
Any suggestions for the problem I am finding. New car purchased early October. Only just past the 1000 miles. Am experiencing an intermittent misfire when the engine revs are between 1600 and 2000 revs. Seems to happen most often after backing off the gas then pressing accelerator again to move on, eg when rounding tight corner/roundabout or just in slow moving traffic. Feels as if the engine stops totally for a fraction of a second then fires up again resulting in a noticable jolt or judder.
Have noticed that it does not happen when the engine is cold. You should also be aware that this car had the tandem fuel pump fail completely after only being driven for 12 miles from new!!!. Took them 10 days to get a replacement from Germany!! Don't know if this is relevant as I think the misfire was there even before the pump gave up.

Why ask the question?

It is 1000 miles - new car - back to the VW garage and let them worry about it and they will give you a courtesy car whether it takes 1 day or 5 weeks - it is not your problem - its theirs.
You have 20000 reasons for them to fix it - you can get your money back if they can't.

My Passat 1.9PD TDI (2002 model) has always momentarily stuttered slightly if I linger on 1800rpm or so.
Garage denied that there was a problem - from new when I complained.
Not got worse in 72,000 miles and never been enough of an irritant to pursue.
No consolation I know to hear that- but after the previous problem and inconvenience you deserve to have it sorted.

Indeed - spend no more time on here. Get the car back to volkswagen, and say "Fix or money back" "NOW"

My Mondeo TDCi also very occasionally exhibits such symptoms at simlar revs, strange, totally different engines and fuel systems, reckon it could be something like the EGR valve fluctuating on the point of the turbo coming on song, it only does it on a steady throttle, again it has never got any worse in 97k miles.

Nevertheless get the dealer to check it out.
