Ive noticed over the past week or two there's been alot more than usual smoke coming out the exhaust, sometimes i can smell oil in it too.

Ive only noticed this when ive been sitting in traffic and the temp gauge is going over the 80 degree mark and also after ive had the car jet washed.

While driving away after and the temp gauge is coming back down to 80 or below, it seems to go away and stop smoking.

I hav'nt noticed any loss in boost and the car seems to pull nicely, but sometime's it has a tendancy to kick a little when giving the throttle a little bit of fun . Im thinkin that maybe the AFM??

Please shed some light as to what is causing the smoke cos im a little worried.
