2.0Tdi VW 2007 Golf Diesel Smoke - Any ideas?

35
Found 7th Sep 2012
I love asking things on here, really good success rate to be honest!!!

Anyways my Golfs warranty is running out in 2 weeks, it went in with smoke issues, basically there is a puff of grey smoke when you start it, then when you pedal to the metal through the gears it is grey/black ish smoke. It passed the MOT on emissions, I just don't like chucking loads of smoke to the people behind me!!

Had 2 Seat Alteas which never smoked and had the same engine.

It has recently had the MAF sensor done, and I have just changed the air filter, VW put fuel treatment in it and said everything else was fine!!

Stop running it on red

Did that, normal apparently. (which I don't believe)
Is it grey or bluey greyish colour

Lol, well, this is a VW dealer so you would think they would be able to do something lol!
Check you don't have a split on the air inlet pipes.

Take it to another vw garage or another mot centre , as some people have different opinions
Do you know exactly which engine it is? There's a few versions of the 2.0 TDI engine, there's two outputs (140ish bhp and 170bhp) and two different injection types (Pumpe Düse (PD) and Common Rail (CR)), the PD170, CR140 and CR170 all have Diesel Particulate Filters (DPF's) but the PD140 doesn't. Have there been any errors showing on the dashboard, either a flashing glow plug light (which bizarrely doesn't indicate a glow plug fault) or the engine management light?

VW dealer is sure to tell you there's nothing to worry about because he knows they will have problems with the warranty company on a 5 year old car with a bit of smoke.

If you're really bothered, take it to an independent diesel specialist and see what he says. Get a written opinion if he thinks there's a problem and take that to the warranty company.

Likelihood is, though, that you'll be told that all 5 year old diesels smoke a bit and your best bet is probably to trade it in.

I wouldn't be so sure, they weren't any use diagnosing faults with my VW based car - they ran the diagnostics on it when I told them I didn't want them to as I wanted them to look at the engine instead and did nothing else. I took it to my normal garage who did have a proper look at the engine ad resolved the issue, I regret taking it anywhere near the main dealer.

Yer I have a feeling they are being a little funny due to the warranty, when I bought it I thought it was like a new car warranty with no worries when things go wrong, how wrong was I!!!!! Diesel specialist sounds good.

I would also probably say it is almost as bad as the car on the left in this next youtube video, only when I am revving the nuts off it though, it only happens when driving, not when the car is in neutral.

Possible.
Could be a glow plug problem
My father in laws diesel had the same thing on start up loads of smoke
Once warmed up a lot better got plugs done now ok
Could be something else though
I have the same 2.0 diesel BKD engine i think. No smoke at all. I have VCDS (vw main dealer diagnostic) and i have a glow plug out and still no smoke.

Get it hooked on vag-com VCDS to check. If your local i can check for you. Or supply you with a cable

With this cable, what sort of SW does one need?
Stick some Redex Diesel in it and give it a good long run and see if it is just a build up of deposits.

The dealership have put in diesel fuel treatment, and I put in some Forte stuff about 6 months ago, made no difference.
Do you have to top up the coolant frequently?
Do you have to top up the oil frequently?
Are most of your journeys short runs/stop-start or long journeys/motorway runs?

It's possible you may have a dribbling injector.

Coolant has been the same since I owned (1 year)
As has oil
Journeys are short ones most of the time.

I am glad you said injector.... lol!

There was a recall on the injectors but it wasn't the normal kind that VW tell everyone about, sometimes you have to ask for it, I may have to ring them about this.

Any other suggestions?
I think the mostly short journeys is your problem.Take on a 100 mile round trip with plenty revs a couple of times and see what happens.Do you use crappy supermarket diesel?

Lol, we do go on long journeys sometimes, still the same, I use Shell most of the time.
New engine?
Your cars a plug, stick in the scrappy or rip the doors of it and use it as a shed for your sheep, boyo
Might be worth looking at your egr valve if the smoke is black and it only does it when your giving it some boot
