Hey all so my 2012 R60 countryman all of a sudden decided to act up last night after filling up my gas tank. Shortly after filling up i decided to do a little wide open throttle (WOT) pull and all of a sudden the car fell flat on its face and the check engine light came up which put the car in limp mode. I shut the car off and turned it back on so it would exit limp mode and it did BUT anytime i would give it gas where the turbo would begin to spool it would begin to misfire.

This morning I decided to do a boost leak test and i found no leaks. I took the car to auto zone so they can read the codes and i have the following:

P0300 RANDOM MISFIRE
p0302 CYL 2 MISFIRE
p144b FUEL CONSUMPTION
p0304 CYL 4 MISFIRE
p15fd ???

I reset the ECU by accessing the service menu on the dash and still no luck, the Check engine light is still lit. I then disconnected the battery overnight and still no luck and i still have the same issue. Does anyone have an idea of what may cause this if it isnt a boost leak?

 

I should also mention that there are no signs of the misfire at idle or light throttle/cruising. It's only when the turbo starts to build boost

 

HPFP, fuel pump. Mine was covered under the extended warranty, same codes. Not a guarantee that is what you have.

 

Did you have the same symptoms though ? Any input from anyone else? I want to be sure before I drop $1k on a part lol

 

I was hyper aware of the potential and I think I caught the issue before it got worse. As soon as the codes hit I made an appointment. I just had the hesitation at start up and sometimes momentary hesitations at highway acceleration speeds.

Check and see if the pump on your car is covered.

 

I'm gonna call the dealer tomorrow. I believe the previous owner had it replaced in 2015 so hopefully they'll cover it in that sense because my basic warranty expires back in February.

*wishful thinking here* is there a recall or something on these pumps ?

 

Ok i dropped the car off yesterday and picked it back up later that day. Dealer states that I need to replace the coils and plugs and that will resolve the issue. Since the coil packs arent cheap I opted to just purchase 2 of them for cylinder 2 and 4 and i bought a set of 4 replacement plugs. My question is what is the numbering scheme of the cylinders, is it Passenger side -> Driver side 1-4 or the other way around?

 

Quick update, i did the coils and its good now. Problem solved..
