D4 smokes a bit under load or is it just me ?

[wlin88]

Hi guys .

Recently got my first D4 , 2011 sdv6 HSE with 1340000 kms . The other day I was driving home after work (dark) and when I take off i can see from my back mirror their is a fair bit of smoke from the back or the my car . It's more obvious as the car behind me had the headlight on . I had td car in the past and it does not look that bad . I don't notice any smoke during the day time though . Since them I have been very gentle on the throttle especially at night as it makes my car looks like some kind if shxt box and polluting the environment . Is that just me been too paranoid ? Also I read about the turbo drain line issues that cause smoky car not sure if that's the issue or not .

Cheers

Btw my missus has a cayenne diesel and I never experienced any smoke under load ... Not what I can see anyway

You may need the turbo drain mod if it has not already been done.
Maybe an Italian tune up :wasntme:

They all do it to some extent.
At night it's noticeable as you commented by the following drivers lights.

The Cayenne should have a DPF which will keep the smoke down....

Yeah your right . Dpf will have more issues in the long run I guess . With out the dfp could be a good thing I guess

Mine doesn't even have a Cat.. (it just fell off one day [emoji48] )

So mine is a little sooty when booted off the line.

It's just a puff as it comes on boost and then dissipates quickly so I don't worry about it.

Haha ... Gold ...

Nothing to worry about, I had a 2010 HSE and it did the same thing, the only person seeing it is you, it's not obvious to the other cars. If it was the turbo drain pipe you would have a very large cloud of white smoke behind you.

Cheers mate . That makes me feel better .

Is there anything we can do to reduce the amount of the smoke ?

You need to get somebody to drive your vehicle and you drive behind to see whats going on.It may not be smoke at all,ie condensation.

At night looking in the dimmed rear view mirror I can see exhaust gasses of some desciption, but of a daytime there is nothing visible coming from my D4.
I put it down to the dimmed mirror and the way the car behind's headlight light is distorted through the higher temperature gasses more than actual soot/smoke.
I have followed my D4 being driven with some spirited acceleration, and there is only the slightest puff, which dissipates well before it would come into view of the rear view mirror.

Thanks mate . I think I will ask a mate to drive the car and see how it goes anyway .

They soot up big time,as can be expected from any highly strung diesel.

Put your foot down. Bugger the environmentals, their agenda has been proven wrong anyway.

Ah bugger, was getting a bit of FOMO there as i can't see any smoke at all.

Gave it a few squirts today andd nothing.

Was about to remove the cats to make some...
