As above, on way home tonight I noticed a puff of smoke in the headlights of the car that was close behind as the old girl came on boost.did accelerate quite sharply so am wondering if this is due to the fuelling spiking as it comes on boost and running rich.doesnt smoke any other time and both exhausts are quite sooty, but its like dry soot not oily soot if that makes sense :)

they do run rich on boost for safety, there are some tests you can do like decelerating from x revs in 3rd etc. could be something moire sinister but if it was just alittle bit an dyou where gunning it then thats probally it

Theres no nasty noises, pulls like a train and doesnt smoke continuosly on boost, just on the initial acceleration as it comes on boost.doesnt smoke when I shut off and she doesnt appear to be losing oil as the level on the dipstick hasnt changed since I changed the oil.just lately she hasnt been on boost for a bit so could it be unburnt fuel just burning off?.running no cats if that makes any difference.when she was at zedworld the other week jeff put her on the conzult thingy and all ok so dont think ats major :)

I bet you couldn't tell what colour it was? If it was dark grey then as Bolt says it could be running a little rich to protect the engine under boost. If it was blue then a little oil could be making its way into the system somewhere. Mine gives a brief puff of blue smoke sometimes - I try not to worry about it - just put a drop more in when I get home :D

No, couldnt tell what colour it was as it was dark, only noticed it in the headlights of car behind.will keep an eye on it but dont think its anything major as it soon cleared and I havent noticed it any other time.im going to put it down to running a bit rich and not having been booted for a bit.shes running a DTA chip so it may be richened up at the upper end of the rev range, would that be right?

Mine is overfueling massively on boost because it's got a Mines ECU in it and stock boost (For now) so when I boot it, especially in the low gears, I huff a big old cloud of black smoke (Unburnt fuel) pretty much every time. Uses no oil or water and goes ballistic when it hits boost, I'm almost afraid to get a controller and turn it up tbh :D

It always looks a hundred times worse when you see it illuminated by someone's headlights - anyone who's driven a diesel should know this. Quite likely that it's just unburnt fuel.

Cheers for the replies guys, much appreciated :).am just going to keep an eye on it, either that or not look in the rear-view mirror when I boot it! :)

Always best to be looking forward when pushing the lightspeed button
