Edition 30 smoking on boost
Ashley g:
My 07 edition 30 has started to smoke on boost. The strange thing is, it doesn't really smoke in 1st and 2nd gear, but other gears on WOT it does. No smoke on start up either or at idle. I've recently changed the PCV valve to the latest revision, and also the oil and filter using castrol 5w30 FST fully synthetic. Doesnt really seem to be using oil either.
Looking in the rear view mirror, the smoke looks black rather than blue, which makes me think maybe it's overfueling? The car has done 54000 miles and has always been warmed up and cooled down properly.
It's running the spec below in my sig
Any ideas?

Sounds like it is overfuelling. I'd get it dyno'd and see what the AFR looks like :happy2:
mo:
What revision diverter valve are you running.Reason i ask is mine was doing the same and seemed to stop after taking of the revision D & going back to my revision C valve. Ive also switched from Tesco Momentum to Vpower for the time being.
Ashley g:
I've recently replaced the diverter valve with the latest revision g i believe. My car has never been ran on anything other than v power. It may be a coincedence but it seems to be smoking now I've changed the oil? It's not overfilled either. Maybe the turbo is on it's way out?

I think your find that most remapped TFSi cars will blow out black smoke as there will always be set richer.. I wouldn't worry unless it is indeed blue smoke or your having performance issues.
