And so it continues....

Still got the exhaust type smell in the cab though, been 11 days now since injectors were changed. Getting egr clean when oil and filter get dropped

[RPWC]

Well, fuel consumption seems to have returned to where it should be, but the smell ,a mixture of diesel and exhaust fumes still remains, although not as strong. Engine oil and filter getting changed next week,also having egr removed and cleaned. So if the smell doesn’t go after that, what’s next?

Pinch the wife's perfume and spray it up the exhaust.

Gas mask?

Going out on limb here but i would change the pollen filter, get diesel on your clothes however small the amount and even after washing multiple times the smell is there, maybe the pollen filter has been contaminated by vapours and although you no longer have the leak, the smell will be there but not as strong ?

Had it in for oil and filter change today,garage didn't take egr off as they said tbey had known of similar fault with Vauxhall, and cleaning egr didn't change anything. A couple of other things I forgot to mention, when revving engine from cold,eg pulling away,it sounds like its pinking . Also sometimes from cold, buf not overnight cold, the display reads"economy mode active".Doesn't stop it from running or starting and everything works My garage thinks its electronic fault, sensor too sensitive,a local garage took it for drive and said he could smell it. Advised dropping it off for further examinations, but I can't spare the time off road. Will see about new cabin filter

[RPWC]

So does anyone think it could be egr related or not?

[RPWC]

Anyone??

[Simple76]

Yes have mentioned a few times it’s more than likely. New cabin filter will mask the problem you have for a short time.

Still puffing our white smoke when cold, after about 3/4 mile driving, it disappears.

Could be just engine temperature related,ecu bsi,,realises the engine is cold so in effect gives you a choke value,even the old petrol engines with pull on choke did the same thing..
Just because they are run by fly wire doesn't mean they do not have to observe the same rules.eh.?.

That could explain the smoke but the unburnt fuel smell?

[white exec]

That is correct: diesels do inject additional fuel (and thus slightly increased idle speed) when engine is cold.
Temperature sensing is done by waxstat-cable-pull on earlier engines, or by electronic coolant temp sensor on later ones. If either misbehaves, fuelling can be affected.

[Peter.N.]

If the compression is good you shouldn't have white smoke for more than 30 seconds or so, is it firing evenly on all cylinders on tickover? The glow plugs should stay on for a little while to improve cold combustion but I have never seen mine emit white smoke unless the weather is very cold - and that could be steam.

Unburnt fuel will usually be caused by low compression or possibly a faulty injector, or on an IDI engine which yours isn't, retarded pump timing.

A quick check on whether you have even compression on all cylinders can be done by disconnecting the +12v supply to the stop solenoid, and then cranking the engine (which won't, of course, start). Listen to each of the compressions, and they should all be the same. If the cranking momentarily accelerates every fourth compression, then there's a cylinder gone leaky. This test can be done engine cold, or engine hot, to inform about each condition.
