Superknock ?
I just took my 2007 Cooper S to the dealer because of poor power. One of the things they mention is...
FOUND TO HAVE SUPERKNOCK FAULTS WITH FUEL
SHUT OFF, RECOMEND MANUAL VALVE CLEANING,
SPARKPLUGS, FLUSHES AND PROGRAMMING.
COMPRESSION IS EVEN @ 170PSI (SCAN FOR
FAULTS)
I've never heard of 'Superknock'.......anyone have any ideas or fixes?

Super knock faults are normaly caused by low on oil, about 3 quarts low,
Check your oil level first,
2007, S models, not uncomman to have to take off intake manifold and use a media blaster with crushed walnut shells to clean the intake valves of coking, I do it quite often, work at a Mini dealer. usualy get misfire faults for the valve cleaning.
Need to check also camshaft timing.
Of course this is all based on you doing your maintance on time.
Check the oil first.
Not uncommon to use a quart of oil every 2000 miles.
I know that you are checking the oil every month and tire pressures?

With the electronic tire-pressure monitors, do I really need to check tire pressure that regularly?
And are you serious about the oil going that fast? *How do I know what oil it's been using? Would this be listed anywhere in the books or do I need to call the dealer? Don't want to put synthetic in if it's been regular oil.
Thanks!
