Cars got 135k on it with the 6 speed and I've been all over looking around and can't find anything other than fuel pump problems. I do 90% of the work on this car myself. I replaced the timing chain and guides around 105k. My BOV was sticking when I did the tear down and replaced it while I had the engine apart. The car runs fine. If I give it between 1/2 to 3/4 or more throttle while below about 3k RPM or pull a hill in a higher gear it'll kick on. But there's no power loss. I'm not getting any codes, except for the permacodes on the O2 sensors after the decat I did around 70K. After about 10-15 miles of driving I can restart the car and the half yellow engine light will go away. Any help or ideas would be much appreciated.

 

You will need to get the DTC pulled when the 1/2 engine light is on. That will tell you what the issue is. Anything we give you will be pure speculation.

 

I've tried this a handful of times. There aren't any different codes stored.

 

What tool are you using to grab the codes? Generic OBD readers will not read the BMW/Mini specific DTCs.

 

I've got a Zurich ZR11, it can usually read everything.

 

A 2014 R60 Countryman should have the newer style HPFP, so I wouldn't think that would be your issue. I had fuel pressure issues with a dirty fuel filter. Has that ever been changed? If the fuel filter passes the vibe check, it is possible the low pressure pump could be on its way out.

 

That sounds like something to do with the BOV again to be honest (or at least the turbo). I have the same symptoms and a reader (Autel MS906 pro) that does all vehicles and it throws the BOV stuck code for me. My cheaper ($100 and less) ODB scanners do not see the code. Seems to happen around 2200-2400rpm (under 3k) while under the same throttle as you describe. I do not sense a loss of power (though there's probably a minute loss somewhere). I've found if I stick it in sport mode and drive it pretty aggressively the code doesn't come on. It will often come on rather quickly if not in Sport mode. I haven't bothered to fix it yet as it doesn't seem to effect performance much and I have a laundry list of other cars that have issues that are higher priority.

 

Update on this. In June of 2022, my belt tensioner went bad and the belt shredded, wrapped around the crank pully and blew the seal out. I was out of state working and didn't have my tools on me. I dropped it off at a shop and they fixed the belt system, and allegedly pulled the pan and cleaned and inspected for debris. 2 weeks ago I started having the low oil light come on with the engine light very randomly. Ended up being the oil pump, which the screen was filled with, you guessed it, pieces of shredded belt. I went ahead and just replaced the pump since it went almost 6 months straight trying to suck oil through 1/4 inch of crud caked to the screen. All issues withe lights are now gone. Still even to the last couple weeks there were no codes stored from that whole fiasco. Thanks for all the guesses though.

 

Something very similar happened to me but they cleaned out the pan and all was good until recently. I changed the solenoids, O2 sensors and MAF but turns out it was the fuel regulator on the High pressure fuel pump. I keep finding conflicting sources so I'm just going to replace my hpfp
