I have a 2012 mini Cooper S with 102,000 miles on it…

My yellow half engine light is on, and I’ve already addressed the code that is highlighted and fixed that issue; however, I’m having issues troubleshooting what these other ones are, Anyone have any experience with this?

I’m thinking it may be a gasket? Loose hose? maybe my turbo? I’ve already checked the engine up and down and not seeing any leaks anywhere, also removed the exhaust manifold, thinking there may have been a crack and found nothing there either but there is definitely a weak fuel/exhaust smell coming from the engine bay.

note: I have already ordered a replacement fuel pump and it will be here in a couple days. (Incase that could be part of the issue.) also replaced the brake sensors and all the brake pads and put brand new seats in it to clear out the highlighted code.

 

@d3vilschoic3 ,

Check:

Fuel pressure regulator check valve
check condition on all 4 sparks plug for oil soak, cracks and its electrodes
swap ignition coil packs to find out any noticeable changes on misfires
Are there any smoke coming out of the tailpipe? If so, what colour?

 

Those codes look typical for a failing high pressure fuel pump

 

There is no smoke coming out of The tailpipes

 

Could very well be the HPFP…….but he’s having issues with these misfirings

 

I've seen misfires as a result of low fuel pressure. Depending on when they were last changed, plugs and coils could be replaced. But, I would look at HPFP if nothing changes.
