white/Blue smoke issue of Grand Voyager 2004 Diesel CRD
 

Please Help.....
I have an issue which to date is driving me mad and the mechanics cant find anything wrong with it!.
I have a 2004 2.8 CRD Grand Voyager, 90,000 miles. The weather turned cold recently and i started noticing excessive smoke when starting the car (more smoke when started in morning) and sitting at junctions for 30 seconds or longer. I looked more into it and saw it was white(ish) blue smoke, so i call a garage who took a look at it, they replaced the fuel filter because it was very badly clogged and contaminated, and replaced the air filter was heavily blocked. Gave it back and said see how that goes, 1 week later took it back as still not sorted, they said i needed a new turbo so they replaced that together with the cambelt. I was told cambelt was done but couldnt see evidence in service book so got it done to be safe. Drove it for 2 more week still smoking the same, i took it back and they told me they have done every possible test on it and noting bad is going wrong with it, they took out a litre and a half of oil because it may of had too much in and said see how it goes. Now 1 week later still the same!!!!!
The garage must think i am mad but i seriously dont know what to do with it. Antifreeze looks good, oil looks good condition, not over heating running fine (apart from excess smoke).
Please can some offer any suggestions on what i should do?
Thanks

hi when you start it from cold first thing in the morning does it take longer to start, or do you need to touch the throttle a bit. or does it start like normal just with the smoke?
next time you go to start it in the morning if you could just go and have a smell of the smoke coming from the exhaust, as my guess is that it is unburnt diesel if it smells like unburnt diesel then i recon it could be glow plug fault or glow plug control relay, the reason i say this is mine is doing the same as in hard to start in morning puffs out white smoke (smells of unburnt diesel) i have tracked it down the relay in mine.
you can find it under the bonnet bolted to the front panel on the right hand side as you are looking at the engine there is 4/5 relays depending on manual or auto you want the far right one its grey in colour all the rest are black is the one you need to look at. i removed mine for inspection and found that one of the pins was discoloured and there was a slight melting of the plastic, i have ordered one its a non stock item but should be in on friday or monday latest i will let you know if this sorts my problem.

could also be egr valve fault?
or dpf?

when starting from cold it starts like normal, straight away.
You are right it does smell like unburnt diesel, would the glow plug come into play when sat at a junction say? because it kicks out a puff or 2 of light blue smoke when pulling out onto the roundabout etc?

Yes faulty egr valve could be problem has the garage done a diagnostics check as it should show up on it I have seen it where it doesn't. You can do it yourself by putting key in ignition turn it onto the first click then ignition on,off,on,off,on leave it on, you should do this quickly I.e within 5 seconds then look at your oddmotor reading if it says done then there is no fault code stored if it comes up with a p0--- code you will need to google code make sure you are in park with handbrake on. You can bypass egr valves and your car will run smoother better mpg and pull better at low revs my old man has done this on his 07 plate mondeo taxi he is getting 50 to the gallon on a run he was getting 44 won't harm it any either he done this at 50k and is on 272k. Judging by what you have described I don't think it's a glow plug problem. Was it a Chrysler main dealer where you had taken it?

It wasnt a chrysler main dealer, it was a general repair centre. Apartantly at the start of all this the 1st time they had the car in i was told they carried out a diagnostics check. I have just done the ignition check like you said and i got a P0514 code.....

It might be worth poping into your Chrysler main dealer and trying to have a chat with one of the technicians as they work with Chrysler all day long and they might of encountered this before explain in detail that you have taken it to a garage and with the symptoms and the work you have had carried out and that it is still the same. Regarding your fault code it is relating to the sensor under the battery it has prob only got a bad connection and wouldn't cause your symptoms. Back to you problem was it as bad thismorning as it was warmer

yes it just seemed the same, i did check on a cold start what the smoke smelt of and its more a diesel smell than an oil smell but its still a pale blue colour...
I have noticed the smoke more once the engine is up to temperature, even waiting at a junction for 10/ 15 seconds will cause a good puff of smoke when pulling away. Last night temperature was done to -3 and pulling out of junctions onto dual carriageways when engine was cold, it has hardly any power once i got into 2nd, 3rd gears, so i think your theory on the egr valve has something to do with the problem. Also to help give the injectors a clean should i get an additive which is put in with the fuel to try and clean out and lubricate the injectors?
Thanks so much for your help on this.

I have just spoken to a Chrysler dealer who has recommended i get the injectors looked at as the symptoms i explained are mostly likely to be the issue.
Would you say this sounds about right?

no probs on the help, i might be way off topic though with egr valve fault though,
mine smokes a bit when you floor it hard and come onto boost from turbo, its worse if you have just been poodling round town then boot it down slip road onto dual carrageway but only for a few seconds also does it if i have a heavy load in it (when on boost) but i dont have any loss in power, so i just put mine down to worn oil seals on turbo

let us know the outcome when it is sorted

will do.

Just a quick note, when you said comes into boost from the turbo make me think i dont think i have ever experienced that in mine. The other day i was reving it to a mate to see the type of smoke we were talking about and the thing never let me rev over 2500rpm......... and even in drive mode it never gets abot 2500rpm before changing down a gear.
Does this sound right?

hi, have you tried building up the revs very slowly to see if it will rev past 2500/3000 rpm try this in park as there is no load on engine as it is not trying to pull the car, if it doesnt then it might be injectors might be low pump pressure but this should show up a fault code. mine is manual 2.5 crd but i can rev right round into 4000+ rpm while in neutral and will carry on to 122mph this is just touching the start of the redline (4000rpm) at this speed i only get 14/15mpg

did your voyager do this before you had the turbo changed i.e not rev freely or hesitate as it could be faulty turbo that they fitted, very rare if it was a new unit but it does happen

wow, 122mph...I cant ever imagine mine getting to that coz it takes ages to pick up when moving along the bypass / motorway.
I will give it a try and see what happens when i build up the revs slowly, I guess injectors / pump could also give me symptoms of the smoke issue too couldn’t it?.

Till light blue smoke when idling after 30 sec
 

Me again,

Sorry to bang on about this but I seem to not be getting this issueresolved.

Just so i might confirm i have described my fault correctly i think it’sbest to summarise;

Light blue smoke when first starting from cold (quite a lot a first but thendisappears after 5 / 10 seconds).

Light blue smoke then re-appears as engine warms up, and really visible whenrunning normal temp. It smokes from exhaust when idling either in gear or notafter being stationary for about 20 seconds, then its continual smoke untilafter i have pulled away then it seems to stop again, (that is unless i stop).I can smell diesel quite often from inside the cab and noticed it a few timeswhen the tank was full and i was getting ,y son out the back door.

Any thoughts / views would be very welcome as I am very very tempted to PXit in for something else.

I know this is an old posting, but the first thing to do with a smoky diesel is to pay attention to the injectors. They can produce white or black smoke if a little clogged, depending on engine/injector design. Modern injectors are VERY different from the old passive indirect injectors. The first give-away is a rise in fuel consumption.

Don't bother yourself with pouring so-called injector cleaner in the tank. It won't work.
The only thing that MIGHT work is putting some "Forte" (accent on the final 'e') diesel injector cleaner into the fuel filter to clean injectors. This is what experienced diesel mechanics do. Failing that, you'll have to remove the injectors for professional cleaning. Make sure the same injectors go back into the same holes, as many of them are "calibrated" nowadays to work with the control micro. Not necessarily on this VM diesel though.

Back in 1984 I bought a 6 cylinder Oldsmobile diesel. After about 4 years, it started giving out a puff of white smoke in the morning on cold start-up. It was a blown head gasket.
