R56 Cooper smoking problem?
Discussion
I have an 09 Mini Cooper which my daughters drive. 77k miles.
It has an odd issue; after idling for a bit, or after a session doing low speed manoeuvres there is a puff of grey smoke, sometimes a small amount, other times more, which then clears. It only happens in those circumstances. Oil usage seems quite high but within tolerance.
I read it might be the PCV diaphragm so I replaced that….No difference. I resigned myself to engine wear and decided to keep going with it until oil usage got out of hand or worse symptoms.
It may be my imagination but it seems worse when the car is pulling away after stopping on an uphill slope.
However after a service and oil change yesterday the smoking seems to have stopped for the time being, and the car seems to be running better… less ‘chuggy’ pulling away at low revs.
Any ideas what’ might be going on?
