Did you have to agree not to tell about the settlement?
What can you tell us? Did the warranty cover it after all?

Hmmmmm. Need more info. I'm thinking joint settlement. Island would have been more boastful if MINI was covering the entire bill, unless there is a gag order.

Well, they say a good arbitration result is one where neither side is completely happy. I hope at least Island is happier than they are; best of luck to you, Island.

Ours lasted 5 years and 71k before it's engine blew up. Even with all scheduled maintanence and lots of repairs along the way.

Interesting posts. Being an ex machinist, working in dealers as a Service Advisor and manager, has anyone determined the exact failure? I mean a burnt piston is very different than valves contacting the piston. Justb/c one revs to 7k which I do repeatedly on my R56 JCW does not mean that caused the failure. These motors have a rep of burning pistons from being lean.

Also being an x-machinist, and motor head, you are right on. If a valve had contacted a piston it would have bent the valve, and you would know it right away. The thing that destroyed this engine was not valve float from too many RPM. It was detonation that probably burned a piston and scored a cylinder wall when it was being tracked. The thermostats on pre-2013 JCW's and MCS's as set by the ECU was 105C. As you state they also ran lean for mileage and emissions reasons. On the 2013 JCW's and GP2's the ecu sets the thermostat at 90C and leaves it there. Maybe BMW finally realized the cause of the burned piston problem. I don't know about 2013 MCS's thermostat settings. I have a 2011 R55 MCS that runs 105C steady state. Also have R56 JCW that runs 90C steady state. Both have JCW temp and rel torque gauges. When I checked into why the difference between the two vehicles is when I found the 2013 JCW and GP2 both run at 90C. Probably to avoid detonation under severe load. If anyone has a temp gauge of any kind on a 2013 MCS please post the steady state running coolant temp. Just curious!!

On a 2013 MCS R59. Normal highway is about 220 degrees. If you go into sport mode it is 185 degrees. If you really push it not in sport mode. It drop temps as if in sport mode.

Thanks for the info on the sport mode. I just had the JCW gauges put on my wife's R55 MCS last week. I had the gauges on my R56 JCW when I bought it new in March this year. So, I thought it unusual that the MCS ran so much hotter than my JCW. Yes, indeed the MCS cools off to 90C when you put it under load, but comes back to 105C in steady state running. I'll try the sport mode in the MCS. Thanks again!

The coolant temp is controlled by the DME. They do run at 220f normally which, historically speaking, is really quite hot. When one runs hard the DME does drop temps to 185f. Not sure if i agree with the sport mode affecting the DME controlled coolant temp as I have gauges, run in sport often incl at the track but on the freeway, in sport temp stays at 220f unless I start hammering it. I dynoed my ride 2 weeks ago and it was lean 14:1or so under load. These cars have a knock sensor so in theory they should not detonate. I never hear detonation but.....kinda loud in there under full throttle. Regardless, a proper tune should really help avoid burning piston an/or valve(s)

This all started with me when my wife's 2011 R55 MCS had a thermostat failure. The DME didn't get a reading from the thermo, and the temp gauge read 0. It gave the 1/2 power light. After a few starts it finally gave a reading of 60C, and the 1/2 power light went out. I took it to the dealer and they R&R,d the thermo and all was well again. I had just put gauges in the car a week before, so without them I wouldn't have had a clue what was going on.

Then I had a question of why my 2013 R56 JCW only ran at 90C or 195F and no hotter by a few degrees, even with an outside AT at 113F in the desert this summer. I know 2 people who have GP2's who tell me their cars also only run 90C. I have to think that BMW finally is realizing that detonation can be a problem in these 1.6L engines. So, it looks like a 2013 JCW is a rare car indeed. It is the only one with the N-18 engine, and a DME that only allows the coolant temp to run no more than 90C or 195 F.

I have noticed on long trips of 2K or more the R55 MCS auto gets about 2MPG better than the R56 JCW manual, so the A/F mixture must be richer overall on the JCW manual which would help with the detonation problem.

I agree also that the sport button doesn't change anything temp wise, as I tried it on both cars with no change in temp!

On a 2013 MCS the coolant temp will drop from 220 degrees to 185 degrees after hitting the sport button. I drive 140 miles a day. On the highway it's between 118 - 220 normally. After I get off the highway I always hit the sport button and it will quickly drop to 185 degrees. I have about 25,000 miles and a Scangauge II. I have seen this happen daily for more then a year. I stopped looking at engine temp. I monitor AFR, coolant temp, batt volt and boost.

I believe what you say. I'm happy to hear that the 2013 MCS's can be cooled off with the sport button. Maybe BMW/MINI are finally catching on that they may be damaging engines running them that hot. I do know that our 2011 R55 MCS temp is not affected by the sport button. The 2012 R55 MCS I had before I bought my 2013 JCW didn't either. Hopefully this is a change for the good in 2013 and will continue in coming years!
