smoke on idle - 06 e91 330d

Hi,

Appreciate this a bit vague but I was unlucky enough to get stuck on the M5 and last night and while sat in traffic, creeping and stopping you know the score (5hrs to go between junctions!).

Anyway, after being sat in traffic for a few hours I noticed that there appeared to be smoke coming from the exhaust (I could see it in my wing mirrors but it was coming from the back of my car) I hadn't noticed it before so presuming it was a recent thing, it was only obvious at idle once I got going again there was nothing visible in the mirrors, I was moving quite quickly once back on the m'way and there was no discernible loss in power or anything and nothing flashed up on the dash.

Has any one experienced this before, should I be scrambling to get my car into my nearest garage?

Thanks for the replies, I haven't actually seen anymore smoke, I did the school run this morning and there was nothing obvious coming from the back that I could see.

It was that dusk\twilight time of day when I noticed it, it was more obvious perhaps as I had cars behind me with headlights on?

deffo notice it more as i said when getting darker/colder etc etc and when headlights are theer it makes it worse and the heat of the exhaust gas also makes it look far worse.
