Have I broken Gee's old car already?

This might just be a 1.8T tuned thing I don't know.

 

Basically I was on an advanced driving assessment / practise run this evening so no caning it etc.  I noticed on two occasions whilst in gear coasting that a cloud of white/grey smoke came out the exhaust.  Enough to fill whole rear screen really  The final time it did it I was going downhill gently in 3rd gear and braking for a red light.  Smoke was definitely not blue - looked grey and wispy.  When I got home I have wiped over the bumper around the exhaust with my hand and there was something that smelled a little fuelly.

 

Now I was never able to replicate the symptoms as it was pretty random and I think it only did it twice on about a 30 mile drive.  Should I be concerned?  The car still has awesome power, no faults.  I will check the oil level in the morning once cold but she is clean as a whistle all other times - just these two times she decided to belch out a cloud of smoke.  The only thing I can think of is in both scenarios I "think" I had just been going downhill before it did it.

 

Any ideas?  I am a 1.8T noob.

Migjt just be a bit random excess fuelling coming off the throttle, misting and vapouring in the hot exhaust? Esp if its when coasting and smelled petrolly.. i know very little though

I know it has a 3" downpipe and no cat.

Probably a reasonable chance its just excess fuel vaping off then

It may have been mapped for abit of popping and banging on overrun with some excess fuel? Does it pop and bang a lot?

Not really.  Nice burble on over run I guess compared to when being just on light throttle.  Note is a fair bit higher.

Fuel is normally black ain't it. Blue is oil iirc. Grey ?? Which shade out of the 50 ?

Like I said valve stem seal are known on the 1.8t to go hard. But I'm thinking blue smoke for them. Mine used to puff a bit on throttle after a downhill coast on one road here in Cardiff never noticed it elsewhere. Angle of the dangle maybe causing an oddity. Used to get a light bit of smoke on cold start possibly grey. Don't forget I'm blue green colour blind so grey can be blue green or whatever my eyes think it is !!!

I would say it's valve stem oil seals just starting to go.
