jules Posted September 27, 2009 Share Posted September 27, 2009 A chap at work has a D2 which he has had from new and has a problem that the dealers can't get to the bottom of which is a cold running problem I have put a few thoughts forward but I said I would ask the question.. it has now power what so ever when cold and needs full throttle to pull away (he is unlike me a sensible driver and not trying to cain it away from junctions just normally pulling away from junctions are a struggle) he has had new AFM new sections of loom newmerus days at the dealer checking the simptons but no joy. I have suggested temp sensors or air leak Quote Link to comment Share on other sites More sharing options...
BogMonster Posted September 27, 2009 Share Posted September 27, 2009 What's it like when it is hot is it 100% ok then? Is there any misfiring and/or black smoke when trying to pull away with the problem? I guess the new sections of loom included the injector harness? Things I would check would be the EGR valve (jammed open - but usually produces tonnes of black smoke under load) and fuel pressure. Quote Link to comment Share on other sites More sharing options...

I would go with Bog monster os this.......fuel pressure or EGR problem........any fault codes or does he have access to live data which might tell us more.
