And the car to date has only used 1 bar of oil - which I'll obviously now keep a close eye on!

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi, have noticed since the cold snap we are currently in (its been -1 the last couple of mornings), that when I start my car I get an acrid oil smoke cloud from the exhaust for the first 10 seconds - it clears quite quickly and then its just steam until everything warms up. The car is kept garaged overnight and is level. I have heard that a little oil can seep into the bores and the oil on startup isn't uncommon with the flat six boxer configuration we have. But was wondering why its more pronounced in the cold weather - I hadn't noticed any oily smoke on start up up to this poing - in 2K miles of motoring over my 3 months of ownership. And the car to date has only used 1 bar of oil - which I'll obviously now keep a close eye on! Any thoughts ? Any ideas why this has just started? is it something I should be worrying about? Migration info. Legacy thread was 87057

POST 2Original post

Not sure about the cold weather, but this normally happens when the car has been running hotter than usual immediately prior to switching off. The oil seepage is usually along the valve guides, but is nothing to be too worried about as long as the car is not over-filled. 1bar of oil in 2k miles is quite good/normal. Migration info.
