Anyone had the same issue? It's not the turbo as its been off and checked all seals and everything fine. It's only on very light throttle in first and second gear it does it in traffic, everywhere else through the revs or driving normally it's fine pulls strong no power or water loss and never overheats. Thinking it could maybe be something like Valve stem seals?

Either valve stem seals or worn piston rings

Valve stem seals are possible but unlikely, worn rings would smoke all the time. Are you sure it's not fuel smoke?

I thought fuel smoke was black? It's 100% blue, noticed it more now the light nights are here

I get fuel smoke on light throttle - its grey not blue.  Gets quite wispy which is a little annoying.  Just think my mapping needs a little fiddling to cope with the 130% nozzles.  If its a mechanical problem then I won't be happy as my DSSR nozzles cost me a lot for United Diesel to fit and balance / test.

Gunna have to get the GoPro in the back of the car I think see what colour it actually is, pretty certain it's blue thow lol. What happens if it's fuel smoke does that mean the map needs tweaking?
