Audi A6 smokes in cold weather
My 2004 Audi A6 2.5 TDI (120k miles) smokes big-time on starting in winter. Is this normal?

No. Overfuelling for the cold start, but by too much. Could be some of the glowplugs are not working.

High quality and refined cabin. Good engines including frugal TDI diesels. Plenty of rear passenger room. Maximum five-star crash test rating. Classy image.
