Hi all, need to pick some brains.
Last night i noticed when I was pulling off from lights, traffic etc that quite a lot of white/very light grey smoke was coming out the back, once I get going and even if i put my foot down it stops, not even much black smoke which is what i would expect from a diesel. So it seems that if i'm sitting there idling for a few seconds it building up something.
No warning lights, not noticing any lumpyness or anything wrong with the engine. Turbo is only about a year old but it is due a service.
Any ideas peeps?
-
you're in a tdi right?....
pull any one of the intercooler hoses and check for oil...generally speaking white smoke is oil....
-
White smoke could be unburnt diesel as well. When glow plugs last been changed?

this ^^ my brothers tdi did this then the turbo went pop get it checked asap before it does any damage
white smoke is burning oil usually

I don't know if they have, not since I have owned it which is almost 2 years. Is it an easy job?
I have no idea what the inter cooler pipes look like or how to discontent them to check for oil.
Should I just get it booked in asap?
-
glow plugs usually only used when engine cold on pre-glow cycle to warm combustion chamber...after that they dont work...
could also be a clogged/oily intake manifold...
whats your mileage?
-
85k ish, have cleaned out the egr etc so it won't be that and i think that causes black rather than white smoke
-
White smoke is normally water getting in the system,unburnt oil is blue smoke
-
Possibly coolant leaking into EGR system through the EGR cooler, common problem.
-
Grey (usually dark) is fuel vapour
-
I have also noticed that it doesn't happen when I first start the car, but after a couple of minutes. Does this help any further?
-

I agree oil is blue smoke. White smoke is usually water.
-
If it is a coolant leak, how serious is it?
-
it isn't necessarily going to be anything serious, if it is only on pull away i would suggest it is a small drip/leak as it would pool while there is no load then not have enough to be noticed on routine driving
i wouldnt panic about it too much, chances are it will be something small and easy to fix
-

I had white smoke on start up or idle on my TDI Passat, changing glow plugs resolved problem. I even remember fitting first cheap aftermarket glow plugs, which did not help, after fitting genuine ones, smoke on start up and idle stopped.
-
It doesn't smoke on startup or idle, just when pulling off from idle. But I might change them anyway.
-
Ok, so it's burning oil, not water, my mechanic isn't sure what it can be at this stage, Turbo is only about 15 months old and i've not ragged it or done more than 10k.
any ideas?
-
update, my mech fears it could be the Turbo, if the warranty company that replaced it in feb 2011 authorised a genuine one then it should have a 2 year warranty, but AMD (who did the warranty work) can't find out until they know who they invoiced etc. and i don't have a clue. what a nightmare as i binned all my old out of date paperwork.
Anyway, he said the oil is dirty and needs changing so he is going to flush it all through, change the filter and go from there and maybe it's just an O ring or something. Looks like it needs a new starter motor too. Oh well, it's been pretty solid until now so thats not bad for 18 moths of driving.
-
The oil is getting passed the seals on the turbo shaft and going into the exhaust causing the0 smoke
-
Also check the breather on the rocker cover isn't blocked
-
After what feels like months, but in reality 10 days, I should be getting my car back today.
It looks like it was something to do with the injector seals leaking oil into the fuel, my mechanic drained the tank and said it was black!! He has replaced all of them and cleaned the whole system out and said its a lot better but said there will be a little residual oil left and will take a few tanks of fuel to clear it out completely.
At least it wasn't the turbo!!
-
Excellent news
-
I've just picked it up and it's still smoking, hopefully this is just residual oil left in some of the pipes and the intercooler, my mechanic isn't 100% sure that it's fixed but he thinks that after a few tanks of fuel it should stop. He showed me how black the fuel was that was removed, the tank has been flushed, filter changed etc. I just feel so pissed off that I have spent almost £700 and it's not perfect. I really do trust him and he only charged me for half the labour but he said it could still be the rocker cover, the fuel pump or maybe the turbo but unlikely.
I hate cars sometimes, if I have to spend more to fix it then I will likely sell it once it's done just to pay off the debt and by a runabout.
-
I really am getting fed up now. No improvements and if not a bit worse. Still lots of smoke and it feels down on power. My mechanic doesn't think it's the turbo because there was so much oil in the fuel. Anyone have any thoughts on this?
-
If its black Ish smoke,, then get the injectors spray patterns checked..
-
No, it's more white/grey. Had the injector seals done and the glow plugs. He thinks it's the rocker cover, fuel pump or turbo. but who funking knows!!!, I'm about ready to dump it in the Thames.
-
Sorry to hear this man, but chin up... Hope you get it sorted soon :happy2:
Problems with cars are never good, until they get sorted out... Then thats what makes it all worth while
-
White grey suggest water, but you say this is not changed... this is a diesel right?
Is it worth putting a standard map back on?
-
100% Oil, it was coating everything, even the fuel was black when they drained it and it stinks. Car feels under powered, can't see why the map would cause this after 18 months.
Yes, 140 Tdi, mapped by AMD to about 190ish and de-catted, 18 month old turbo, all serviced and had a good flush.
I think I will have to sell it once its fixed just to pay off the debt it's caused trying to fix it.
-
Do they have a similar pump set up? oil getting in the diesel that way?
-
I really don't know, so many ideas have been getting thrown around that i'm just lost. Can't keep up this trial and error stuff though.
Just to add, it has been doing it when putting my foot down sometimes or if I go round a corner quite hard. But mostly when i stop start in traffic, it leaves a BIG cloud behind me, also noticed it if i am going down hill in gear but not accelerating. Not sure if any of that helps diagnose at all.
-
seem to be well down on power now too.
-
Sounds like valves stem seals possibly to me... ? But then like as you say i'm guessing and giving yet another possibilty, hopefully the garage will pin point and sort, maybe upgrade the garage to one which has helped other members sort their issues like this...
Anyway hope you get it sorted mate...

UPDATE 3
The turbo was examined and the blades had some marks on them, they think that there may had been some debris left in the intercooler when the last turbo was changed. So It's a new Turbo, intercooler and while the front end is off the started motor is being replaced as it's a bit hit and miss, I think I will be lucky to have change out of £3000 after all this. Oh well, what ya gonna do ah!!
-
Why would debris get from the intercooler to the turbo? Thought it blows one way?
But hope you get it sorted buddy...
Dom
-
Not sure, my mechanic heard that it's best to change the intercooler when you change the turbo, this wasn't done before. I don't know much about all that.
-
I also get smoke when pulling off (havent read all this thread)
My oil usage is rediculous, it has gone from half the dip stick to almost minimum on 268 miles, normal?!?! My garage is looking at it all tomorrow so I'll let you know what they come back with I am going to ask them to check every nook and cranny...
-
I was leaving massive clouds of smoke by the end of it, hopefully yours is a simple thing, but have a read through the thread, see if you think it's the same. For your sake, i hope not.
-
Thanks mate, just read through it... I feel for you, that's a lot of wonga you have to part with... Will find out tomorrow, have not noticed any loss of power just smoke when pulling away from traffic (much more visable at night) oil consumption is horrendous and smoke coming out the back when started from cold...
Hope your problem is sorted too, seems like it has been a long and fustrating battle... :confused:
-
had the same issues with mine last year--also check the breather on the rocker cover isn't blocked as it will chuck out the oil through the turbo
-

My mechanic thought this could be an issue.
I had a lot of oil everywhere, the fuel was black, but since the initial work was done with the injector seals there doesn't seem to be any oil in the fuel as he checked it when it first went back. It's possible I had two problems.
-
mine never had oil in the fuel--think it was down to the breather been blocked and causing 5 turbos to go :signLOL:
-
Is it a case of just cleaning it out or do you need to replace the breather? any idea on cost?
-
Sorry to hear about your issues, but not sure if this would help cut some of the costs whilst giving an upgrade. ;)

Could drop it at AMD as well.

Thanks but I believe it is being done as we speak, also i'm looking forward to a two year warranty from VW!!!
-
the breather is part of the cover which is a bit stupid--cost me£100
-
All fixed!!!! Total spend £2500. But that includes a service, starter motor, intercooler, Turbo, glow plugs, injector seals, other sundries and a hell of a lot of labour. Most importantly, no smoke also forgot how fast my car was, it must have been down on power for a while.
One thing i did notice is the turbo doesn't wine like a siren anymore, even though it was meant to of had a brand new turbo 18 months ago, which made the sound from day one.
This is me now > :laugh:
-
Good to hear its all fixed
