smoke from exhaust on heavy acceleration

[BIG DIN]

Hi guys this has been buggin me for a while now.
Every time I give it a bit of a boot and look out the rear view mirror all I see is a massive cliud of smoke. Its more noticeable in the night when theres another car behind me and you can see it in there headlights. Its really quite embarrassing. 
I have recently given it a full service with new air filter and changed the breather filter thing. I thought after using a few of the additives it would clear the problem but it hasnt.

Any help or advice would be greatly appreciated.

Probably nothing to worry about.  You've had the key bits changed.

I used to see smoke on mine too under heavy acceleration - especially at night - so it's fairly typical as there is no DPF on that generation of X5.  Sometimes I used to take mine out and put it in 'S' mode to force the rpm up further so that the exhaust got much hotter and the soot could burn off.  Worked for a while afterwards abd then needed doing again.  If I did a lot of low speed driving then the smoke was more apparent the first time I used the engine 'in anger' shall we say.....

Mine did that until I changed to a vortex breather and that cured it completely. You say you changed the breather filter so not clear if you changed to the vortex which is a whole new unit, not just the filter; assuming you did not have the vortex type already.

I had a Shogun Sport ( challenger 2.8 TD ) that was the same, when I took it to Mot, he advised me to take it on the motorway and rag it in manual to clear it out. He said it was common on auto diesels with big engines, they rev too low due to the auto box changing up before it got chance to clear out the soot.
As X5 sport says, get it revving and clear its throat.

Thanks guys.

Denis O I meant the filter near the air filter which I changed including the housing for the new design one.

It is quite embarrassing though brings another meaning to the saying ' I'll smoke ya'  lol.

i have the same thing with my 2005 3.0d, however i find different fuel companies can make it better or worse

In Australia i either use Caltex or BP all others seem to smoke more.

the other thing i notice is that if i start and move my car a couple of times at home in the driveway the next time i use it, and give it some power it seems to have to clear all that soot out.

i reckon that the rear mufflers told alot of soot if your just pottering around, and then when you nail it, out it comes
