When Is the N18 a 3-Cylinder?

Apparently, at 6 AM on the way home from work in 10-degree weather. That's when one cylinder quit firing & the engine light came on, 2 miles from home. Fortunately, I made it home, then called the dealership as soon as the service dept. opened. It's an hour away, so a flatbed is coming to pick up the car in a couple hours.

Never had a car break down at 9 months & 9,000 miles -- hoping it's just something minor like a loose wire!

If you are lucky, it will be one of the coils...

I so hope you are right!

The flatbed arrived around 11 AM. When I started the car so that the guy could drive it up to the truck, it seemed to run fine for the first two minutes or so, then began misfiring ever so slightly. That makes me think that it is a coil, since bad coils sometimes seem OK when they're cold.

I've experienced mechanical failures like dropped valves, and this didn't make any of those noises, so I'm hopeful.

When it happened to me, you could not discern it was running on 3 cylinders on idle. Only when revving it did it become apparent.

That's how mine was when I started it for the tow guy, but when it acted up earlier on the way home from work, the cylinder wasn't even firing at idle.

That's what I'm hoping for. With the weather forecast here for 6"-12" of snow, and the dealership being ~50 miles away, I may not get the car back before Tuesday in any case. :-( I like my wife's Kia Sorento a lot, but it's no MCS.

The dealership just called to say that it's a bad high-pressure pump. At 9,000 miles! >:~( The car is supposed to be ready tomorrow afternoon, so I'll make the two-hour round trip to pick it up after I get off work at 6 P. M. tomorrow.

I know it's probably premature to worry about overall reliability just over a fuel pump (it is, isn't it?), but this is the first new car I've bought since 1979 that hasn't been a Ford, and every one of those was extremely reliable; none ever broke down on the road.

Now that's a scary but likely accurate marketing tagline: "Ford proves more reliable than British-German import"

I'm with you, OP. We have had probably 20 new cars between the two of us, starting with a Camaro Z28 in 1980, and the most severe under-the-hood problem we ever had was a bad throttle body.......ever......

We have two N18's in the garages, our first Minis, and while I'm not quite on pins and needles, I am concerned......

I hope this is just a blip for you!

Mini changed manufactures over these HPFP's like a hot potato! I've seen some 2013 JCW's with a completely new design that doesn't remotely look like the one we're used to.

LOL! My first car was a 10-year-old 1960 Jaguar Mark 2 -- you can just imagine how reliable that was!

Yes it's true. My 2013 JCW R56 has a totally different HPFP than my wife's 2011 R55 Clubman S. The fuel pump on her car went bad at 16K last October. I was told the 2013 JCW pump is not interchangeable with her pump. The JCW pump stands off the head on legs, and only contacts the head on the legs and where the drive off the exhaust cam enters the pump. Also the 2013 JCW engine temp never gets above 90 C (194 F) whereas the MCS engines run at 108C (226F). I think that has a lot to do with it too, as petrol starts to boil at roughly 142C (160F) causing lack of lube from the fuel in the pump. I had posted this theory on another thread in the past.
