I was driving my 2001 Boxter when white smoke began to pour out of the exhaust. At first it was intermittent, then it got very thick. No warning lights came on. I pulled over and was told flames were coming out of the exhaust. Needless to say it was towed to a shop, where they're still looking at it.
Anyone have a clue as to what it might be?
