They also said it is normal. It has done it since day one. Our car doesn't go through oil either. I have noticed quite a number of D4 TDV6 doing the same thing.

I think everyone is forgetting that all diesel engines blow smoke of some sort.......especially under heavy acceleration.
Was following a brand new Mercedes 4WD wagon the other day and it was blowing heaps of smoke.

Craig,
The issue I have with this is that my previous diesel was a D3 SE, same motor used the same way and driven the same way and while it did blow smoke under heavy acceleration it was a puff, not a bloody great cloud that obscures the car behind. I'm more concerned with the amount, not the fact that it does it, particularly when compared to its predecessor.

Which means the latest vehicles use more fuel in this situation?

I also do a lot of driving during the day & notice a lot of diesels smoke,particularly under hard throttle.

I hear you Steve. Was referring to those with little smoke...........possibly those coming from a petrol to a diesel for the first time.
I have had friends following me say "your car is blowing smoke when you take off from the lights". I say "thank goodness for that".

Your bloody great cloud sounds like it needs attending to.

Let us know how you go. It may need a re-map or software upgrade.

Cheers, Craig

Yes engine tune has changed & the D4 2.7 is slightly quicker off the line & through the rev range, I am not sure I would say they use more fuel, I would lean towards & agree with many clients saying that they are marginally better.

Dark Tint does wonders & so does a wheel carrier.....

I would have thought blue\grey smoke was oil burning,
and that over fueling would be black.

LR Oz may say its normal, but is is right ?
