Anybody else experiencing an incredibly noisy engine when cold starting since the weather became much colder ?

My 10 plate (bought because of issues with the 07 it replaced - the infamous cold start/diesel type noise followed by using more oil than petrol after being 'fixed'...)

The noise is a little like the normal tappetty type noise the engine always makes but much-much louder. It's pretty bad at idle but when revved (even for normal driving) it's, let's say, 'head-turning'. It settles back to normal once the engine's warm.

Back to the dealers ? (this'll be the third fix so far, at only 6 months old, because it's already had a front wheel bearing and a 'kinked high pressure line causing the engine mgmt light to come on).

To say I'm not happy is an understatement - this is my 4th Cooper S (52/05/07/10) and without a shadow of the doubt the turbo cars, in terms of reliability, are a massive disappointment - if only they could've made a clean/economical supercharger!

OK...no comments....so I'll fill you in on what's happened so far.
I've now been without the car for an entire week, it appears that I have the same issue with this car as I did with the 07 one - namely the timing chain tensioner (now correct me if I'm wrong but the 184HP engine was supposed to have fixed this wasn't it ?)

The dealers have said that the car will now be several more days as BMW have asked them to perform cold start oil pressure tests on the engine over the next few days.

To say I've lost all faith in the car is now an understatement - I should have a few grand and gone with a Cooper instead, since they don't seem to suffer this issue...

its sad to here. I got a second hand 56 in feb and traded it today as it done nothing but in wrong. I feel for you thinking you might get trouble free motoring with the latest model. I certainly wont be going anywhere near this brand again. All in all i lost 7 grand on that car in7 months not good
