I have a 2011 jcw coupe 12000 miles.

These last few weeks having driven say 10 miles (slowly) when parking up, a blip on the throttle can, now and again, produce grey/blue smoke, quite a lot, enough to cause concern, but only once, blip the throttle again and nothing ??

This has happened twice in as many weeks, and seems to be intermittent.

Any ideas please ?
Thanks

 

Start with taking your intake tube off your turbo and look for oil in the intake tube. If you have an overfill situation your car may be sucking oil from the pcv into the intake. Or the Turbo seal may be going bad and the only way to know for sure is to take the downpipe off and inspect the exhaust side of the turbo for oil.

 

Thanks for your Input, will do that.
