All Audi cars (all German cars?) are shipped from the factory w/ their engines covered in Cosmoline.

Exactly. Turbo broke, replaced, haven't smelled it since.

Mine did this when it was new. At one point I had white smoke pouring out of the front passenger wheel well (not a lot, but enough to cause serious concern). But right after that it stopped and has never done it again. I could never see anything wrong, and I've had it looked at, to no avail. <p>I figure maybe there was some undercoating overspray on the exhaust or catalytic converter, or maybe it was the turbo housing "breaking in". <p>There are no visible oil leaks on either the turbo housing or around the valve cover, but shortly after the smoke stopped I noticed a rather audible "rattling" sound under boost at low RPM ("rattling" stops if I ease off the gas). I figure this is either turbo spool up or a noisy wastegate. Time will tell...<p>Paul 98.5 1.8TSQ-Tip (13,000 smoke-and-burning-plastic-smell-free miles, fingers crossed)
