Mini smoking at start-uo

Hi All,

I've just bought a Mini Countryman ALL4 Cooper S (petrol), made in 2011 (R60) with about 50,000 miles - I've noticed that on start-up, I occasionally see smoke coming from the exhaust - nothing major, and it usually disappears after a few minutes, but is this an issue, should I be concerned, and is there anything I can do/should do about it?

Many thanks,

Tony

It would depend on the colour of the smoke

If it's just on startup it's probably/hopefully just caused by condensation in the exhaust, probably/hopefully nothing to worry about.

You won't know for sure until you have different tests done.

So, update, changed the engine oil from to 5W40, and it has cured both the smoke at start up, AND it isn't using oil anymore! :-)

might want to check with mini main agents on any recall for thermostat housing as on psa cars they have one due to a number of faults and one being get to hot and oil goes very thin causing smoke and oil loss, as a 5/40 is a thicker oil at 100c ie the 40 part of it would make sensor that yours could be running at higher temp ie sign of thermostat housing issues,, link below for upgrade housing t=and the wiring for it ie 2 pin is a 4 pin on revised ones, i would say its a must do job on any prince engine ie petrol mini
