Did you have to change the engine number on your lisence disc etc?

The theories are all good but to keep the car as standard as possible and within the program threshold a thicker head gasket must be added to the cooper s and most minis are now reprogrammed to shorten the service intervals to 12000kms. replacing the HP pump only helps for about 2000km before it reoccurs
Hope i could shed more light on the super knocking.PM me if you have any other suggestions and conclusions

Í have the same problem, mine is a 2009 JCW, I'm surprised to see a 2010 sill having this problem. At about 3000km I had the timing chain recall done. The super kocking was there but not so often then about 6 months ago it was more frequent. The filled in injector cleaner I think but it got worse. At around 50 000km th turbo siezed they didnt know why and just replaced te turbo uit and all feed line to it. now at 65 000km the turbo shaft has excssive play and it has been replaced again they dont know why. About the super knocking they say that BMW is working on a fix. But I also see many had turbo failures aswell what is the cause of this? Is that cam pullies story a true story? If service intervals is too long then my 135 might also end up with the same turbo failure? What happens if the engine fails just out of motorplan is BMW gonna cover us for their Super Problem with no fix:fencelook: Love the JCW too much to let it g but if out of plan I would have to sell.
I think it relates to carbon build up, whats your take, George?

BMW sent me a letter two weeks ago stating that super knocking is a safety feature, and no consequential long term damage will occur due this. This is quite strange as the engine was initially replaced due to the super knocking experience. I have found research papers and articles from academic journals, including the International Journal of Engine research, which state that super knocking can cause serious damage to the engine. One article states that there is no exact cause.
BMW sent another letter stating that it could be due to carbon build up, fuel grade, driving conditions etc.
I did less than 50ks after they put in a new engine, so it definitely can't be carbon build up or fuel as they would have drained the fuel if they are stating fuel grade.
Dean, they have not responded to my concerns regarding what happens after motor plan. It further concerns me that I cannot sell the car to another person now knowing it has an unresolved issue, as per the Consumer Protection Act. I will not get a fair retail or trade value.

Hi guys
So our issue re-occurred after engine change and injector clean, etc.
Car is out of Motorplan but I have been complaining to BMW SA before plan went out so car went in for a diagnostic on Tuesday and a PUMA case was opened. Apparantly BMW Germany is close to finding a resolution. I'm not holding my breath.
I also want to see this issue fixed before we sell.

Hi Neven, has any new info come up?
I was looking at picking up an 09 Cooper S, it has a MP comment for piston rings that rang up a bill of 78K, and this thread stopped me dead in my tracks.

Update: Car was with Menlyn Auto for about 2 months for tests and intake cleans and software updates. They tested the car extensively under all conditions. I didn't believe it was fixed but after trying very hard to re-create the problem I was unable to so seems to be all good now
Apparently BMW is designing a new intake to rectify the problem. :thumbs:

I use injector cleaner every 3000 to 5000km's. Seems to have helped me
out. Also try using the best quality fuel. Dont add to much octane booster as this can fry your plugs with excessive use.

Hi guys,
I am the proud owner of a '09 MCS with a grand total of 84k km on the clock.
For the last year and a half (at least, most probably longer) I have been experiencing cold start issues (Rattle of death and all that). The timing chain fix was done twice on the car (first time at my request, then about a year later when BMW called me about the Technical Notice). According to invoices from BMW I have had this problem resolved twice already.
Additionally, I have also noticed the symptoms some of you had described earlier in the thread. There is a sudden, short loss of power, and a metallic clank sound (lasting maybe 1-2 seconds) when accelerating hard. This is especially noticeable in 3rd and 4th gear, from when accelerating from lower speeds and usually occurs just as the turbo is spooling up (~2800 rpm).
I may be wrong in this assessment, but I would guess that the sound only happens when the turbo is "over-boosting".
All of the above went on for a good year or so, as each time I took the car to BMW to get checked up on, they would come back to me and say that everything is ok.
Recently, I had my "Check Engine" light come on, while cruising on the highway. The engine was still running, but as soon as I stopped on the shoulder, I turned it off.
Got towed back to Northcliff Auto. I made them aware of the issues I had been experiencing. They performed the diagnostics, and said that compression in 2 cylinders had been lost, and that the engine would be replaced (all luckily less than 1000km till expiry of motorplan).
Now I come to you with the question of what you think I should do next. What specific things should I be on the lookout for when the car comes back to me? Should I just get rid of it and cut my losses? I really love the car, but do not want it to become a massive financial black hole.
What else could be damaged in the car, due to the prolonged wear of the timing chain? Should I be worried about the turbo going?
Also, when BMW replaces the engine, is the replacement the same engine or one of the newer (135kW) units?
Apologies for the slightly rambling post, and thanks in advance for any and all advice.
