R56 2012 MCS Half engine light, lumpy, no power?!

[Stick Legs]

Hi,


My 2012 Mini Cooper S was running fine until Monday when overtaking there was a loss of power, half engine light popped up & stayed up, feels like a misfire, won't rev past 4000 and if you hold steady revs the half engine light turns to an engine light (all black inside). (I found this all out on the short drive back home)

No obvious issue in the engine bay, oil and water seem okay.

It's under warranty so it will be going in to Mini to get looked at as I only purchased it at the end of January, but I thought I'd start this to let you all know what it turns out to be.

I'm away at sea now until the end of July so won't know until then, but will be interested to hear anyone's views.

Thanks for that chaps, as I said it's under warranty so will be depositing it at Westerly Bridgwater once I get home.

28000 miles, seems early for a failure? It is also 8 years old. Depends on which way you look at it.

Well I had it looked at by Westerly Bridgwater.
Coil pack on Number 4 Cylinder.

All well now and hopefully nothing else rears it’s head!

When a coilpack goes, you're pretty much guaranteed the rest of them will fail soonish afterwards... I changed all 4 when one failed, couldn't be bothered with a trickle of coilpack failures over the next few months!

Hopefully all under warranty!
