Help
So I have a 2011 mini s got it a few months ago not long after got a CEL put it on the scanner an get misfire in cylinder 1 so I change the spark plugs and coil packs seems to work. Then last week I’m driving hit the gas and it stumbles and CEL comes on then goes into limp mode. Put it on scanner and I get multiple misfires different cylinders different times completely random. Everything I’m seeing is it’s probably the HPFP. I got a bmw/mini scanner to check the fuel pressure and high pressure is reading around 4.60-4.87 MPa right after start up on idle. Low pressure is 72.5 psi My question is does it look as if that’s what’s going on

The N18's don't have as many HPFP issues, but they still do. If yours is indeed bad, I'd check out this thread here: HPFP warranty replacement for N18
