Cloud of bluish/grey smoke at high speed

Sebster · 08-11-2007, 15:27

Hi all

Was just giving it a little bit of welly with a golf 2.0 TDI in tow (not attached

) up a slip road and onto a motorway, when reaching a pretty high speed in 6th with my right foot still planted there was all of a sudden this large cloud of blueish/ grey smoke that billowed out of the exhaust, not the usual sooty smoke you allways get under acceleration.I lifted of immediately and it was gone as quick as it came,so I am slightly worried now. I tried to reproduce the smoke whilst accelerating hard in lower gears and nothing so whats going on?

Is it turbo hose leak at only at high pressures ?or something worse?

Car has been remapped,but I do drive it kindly and has been thoroughly serviced at the 20 000 mile point as well as at 10 000miles and even when I bought it at 14 000 no warning lights show and no fault codes to report before or after re mapping and that was 3 weeks ago.

any suggestions?

Sounds like a puff of oil given the colour. The intercooler pipes do get a little oily, so it may have been from there. Just a guess btw.

I hope it was the turbo just clearing its throat
