I have a 2001 E320 4Matic wagon, (purchase 9/06 w/52Kmiles) with 62k miles now. All documentation for dealer service from first owner. No oil usage, Mobile1 (5w/40). I move the car dead cold from the garage or another place and it runs about one minute or less and park it, then later on in the day I'll start it and see the puff of smoke. On several occasions in the last 9 months I have noticed this bluish/white puff of smoke from the tail pipe upon start-up. Is this something that is know to exist on this engine, is it a fluke, anyone have any info or experience on the matter. The dealer (car under StarMark) stated something to the effect that MB doesn't allow for a leak down test under the warranty guidelines. Is something rotten and is this the begining of a slippery slope?
Thanks, Dennis
