Started the GTI this morning....

[Dirty Five]

not a very cold morning on the scale of things, first time i have driven it in about a week and a half, Turned over and conked out, then ran very lumpy, missing really badly 

I stuck with it for a min and it cleared up then drove fine, my wife is about to take it out now so ive got my head out the window...

... started fine 

so what the hell was that about, should i be worried

Could be the PCV..

Disconnect the hose which plugs into the inlet manifold and whilst its running block off the inlet manifold with your finger, if it suddenly runs perfect then thats your problem..

Generally if its the PCV then once its running bad it would stay like that though..

[Dirty Five]

Is this quite a common problem then? i'll give it a go if it does it again 

[jonnyc]

Yeah about as common as the DV's breaking up.. Could be worth taking a look at that also..

A broken DV diaphragm would also give a very uneven idle on cold start.. Sounds almost like your running really lumpy cams??

I would think more likely cold and damp were the cause - I wouldn't worry about it unless it does it again.

yep thats exactly how it sounded!

Iwa hoping it was nothing or a simple fix, so all news i wanted to hear

ive had this happen on a really cold morn but only a couple of times seems ok the rest of the time i just blamed the cold

I doubt it's anything as complicated as the DV or PCV from standstill - It wouldn't have run fine after starting.

I've had a very similar problem - They don't like being left for more than a week without running and it's a common battery issue with the Mk5 GTI so I've heard.

That'll teach ya not to use her!!
