Have you been getting courtesy cars during the periods the car is at the dealers?

Right so the wife and I have had enough of this nonsense. 11000km's; Knocking all the time, 3 turbo's down with all sorts of other issues and engine light on again this weekend. :bangdesk:
Car is being picked up this morning after a few phone calls and Mini/BMW head office are sorting it (hopefully meaning a new car).

Its really shocking the issue of super knocking. They revised the engine completely at the end of 2010, one would expect all the issues to be ironed out.
Apparently theres no fix to it, all they do is throw in a fuel injector cleaner additive to the tank to help the problem. Too much carbon build up in the engine :fencelook:
Why did the car go thru 3 turbos? Does the issue cause the turbos to fail?
I doubt they will give you a new car, maybe a new engine completely.

So car went back in last week for the software update to retard timing. Took car for a test drive and it didn't feel like a Cooper S. Advised I will not take vehicle with that level of performance!!! Pointless buying a Cooper S if it doesn't go like one should......So we now waiting their further investigation.
So sad that this issue can't be fixed.

So in the week preceding the sale of my car, the same week I put up the advert, my engine went again. Trust me when I say I had a hard time explaining to the prospective buyer why the engine was replaced!
When I got it back I had a full 3 days to enjoy it before it left my hands. I don't know what they did but they somehow fixed the problem!
I spoke to Glen at Auto Alpina Boksburg and he said its kind of a mystery problem with those engines. No one knows what or how it happens, and after I told him mine disappeared, he could not explain how or why.
Sorry to hear your problems bud. These cars would be so much better just with a slight change of engine.

Thats such a sad story. Sorry to hear this. I too had the super knocking issue and mine seemed to resolve itself with good fuel, injector cleaner and halving the service intervals.
She still does it from time to time but only if she is cold. If I let her warm up for about 15min of driving, she doesn't knock anymore. Its a funny story this...

I used to drive the same in my THP cars... why not try the new Engine 95? I hear they say the octane rating is closer to 98 won't hurt to give it a go in one or 2 tanks?

I only use Shell VPower 95 and have tried the new Engen Primax 95 and ill be honest its just as good if not better.
Though, Shell 95 VPower is still my first choice. All other fuels cause major knocking on my baby.

Im glad thats working out for you :thumbs:
But I feel Its not supposed to be that way :fencelook:
Buying a 'performance' car the power should always be available no matter what fuel and this knocking can break the engine :fencelook:
Seems like the supercharged models are more reliable :argh:
