Hi,

I'd like to say a big thanks for all the info you've got on here! I'm so chuffed to find this forum, i used to have a hilux surf and with it being an import and relatively uncomon there's a great forum for them, absolutely priceless, but only £5 a year donations asked to keep it going!

Unfortunately after searching here i can't find anything to help with the problem i'm getting.

I've just bought a 2002 1.9TDi passat with the 5 speed Tiptronic box. So far i'm loving it to bits, showing 50mpg with cruise control set to 70! Better than i'd hoped for, i was almost more relaxed getting out after a 2 hour drive than when i got in!

It's got 170,000 miles on the clock but a complete service history and it all feels like new, the engine feels mint and the mpg suggests a well set up system so i'm confused about what might be behind the only problem I'm getting, a definate juddering, usually after coasting at around 1500rpm when applying light throttle but sometimes at higher revs too, sometimes its just a couple of shakes but if i'm in traffic at low revs it can be an long series of rapid juddering. I've taken into account i might be being over sensitive with a new car but still i'm certain something is up, i just don't know if it's serious. It's the 3rd auto i've had (though first tiptronic) and i never had this before.

The gear changes are pretty smooth whatever my right foot is doing, doesn't lurch much or crunch going from P to D, so oil condition ok? All the tip functions are happening on cue, goes in and out of gear without hesitation, so tip ecu ok? The mpg is book numbers so seems to say there isn't too much slip in the box. Seems all ok! (from what i know )

I'll try and look at the engine mounts tomorrow but do they need to be visibly rotten to be in need of replacement?

I was wondering about fuel delivery but it's all smooth with a heavier foot and ticks over lovely, the engine seems sweet as a nut. I noticed a couple of times the revs fluctuating slightly for no reason, maybe up and down a hundred rpm from a steady 2500, but it's not at the times i'm getting the juddering.

I'm missing something here, i'm sure this can't be normal, it's not horrific but plenty disturbing enough to warrant an investigation, at least to rule out a serious problem waiting to happen. That said i'm not keen to take a blank check to the main dealers for them to guess me into poverty. If anyone can shed some light i'd be realy grateful!

Many thanks
