Meant to report back that a new set of plugs and the new coil pack and cyl 2 fixed the problem entirely. The old plugs were in dreadful condition (I'll try and post a photo below but I've never had much luck posting photos to this forum) which is no surprize as they had 63000 miles on them.
I imagine long slow drives in commuter traffic doesnt help the condition of the plugs. I advised my wife to give it a bit of the Italian tune up every once in a while. Wonder what the community thinks on that topic?
Thanks for guidance and help as always.

I’m really worried now for mechanical damage as the noise from the valve train is pretty loud and rattly. Fingers crossed I get the plugs in and it makes a difference.
I did read that a sudden out-of-the-blue misfire could mean mechanical damage and that’s what happened here. I guess under load worn out plugs could suddenly give up and fail.
2013 with 60k miles and original plugs....hope that’s it
Thanks

Yes that’s exactly the empty plug. Thanks for clearing that up.
I don’t see any other potential vacuum leaks after a good visual inspection. As I said I replaced the broken snorkel as I thought that was a source of a vacuum leak.
I am looking into plugs and coils as that is the next easiest thing to check. Been reading bout broken valve springs too so hoping it’s not that.
Will report back soon. Thanks Adam

> fuel - problem with high pressure fuel pump or fuel injector
> ignition - coil or plug issue
> air - vacuum leak or carbon buildup
There are probably a bunch of other potential causes, but these seem to be more common.
Does the empty plug look like this?
This is a coolant temperature sensor that is no longer used, replaced by new sensors in the updated thermostat housing.
edit: Here is the link to the hose that eliminates that obsolete elbow with the sensor.

My wife’s 2013 Mini Cooper S R56 just sprang a misfire. Was out getting food one night recently. Gave it some welly to pass a vehicle turning, and boom, began running rough. Really lumpy.
Immediately thought misfire. Sure enough got it home and plugged the OBD reader in and got the misfire on cyl 2 code (I forgot the exact code number - P097 or something, but its not important as it was a very generic code)
Did some research on what causes misfire, and of the various answers the vacuum leak stood out to me. The snorkel tube that goes from the air box to the turbo was cracked and did not seat on the turbo flange well. I noticed this last time I changed the air filter and kinda bodged a fit. It had been running fine but I assumed the bodged fit had come unfit and was leaking.
I replaced the snorkel and it fits perfectly now. However the misfire is not cured. Damn.
I noticed while I had the snorkel off there is an electrical socket down under it that had nothing plugged in. I looked all over but could not find a cable or wire that should be plugged into that socket. I have a photo I’ll try to upload. I never have good luck trying to post photos here for some reason. No idea why.
Any way, 2 questions? 1. Any ideas on the misfire, maybe specific to the Mini? 2. Any ideas on the empty socket/missing wire?
Thanks. Hoping with the community help I can fix this without going into town to the dealer.
