I need some help/advise/suggestions please! I own and absolutely love my 2014 Mini Cooper S. She 103,000miles on her. Just recently it started to get a hesitation when you hit gas to pass another car, I can’t figure it out. I have replaced plugs, ignition packs, purge valve, air filter, cleaned (not replaced) MAF, have done intake valve cleaner and injector additive. I am a stickler for oil changes and have been done regularly. It has ran like a champ before this and I just want her back. Any help or suggestions will be greatly appreciated. I have done all this work myself because I am a hands on and don’t want to be taken advantage of. I appreciate your time.

 

fuel/timing ?

 

Any codes stored?

Maybe its time for injectors?

 

Also compression!!

 

First guess would be injectors, second guess would be compression or something involving carbon buildup (I don't know how much trouble the F56, vs the R56, has with carbon tho). I'd also be trying to hunt down any codes, even transient, documenting misfires and/or anything that had a particular cylinder "making itself known."

Side guess would be something brewing with the turbo -- my RIP R56 was doing something like this, throwing a private/special/whatever code and the "half engine" light, I managed to get as far as figuring out the mystery/special code had something to do with the turbo but never got the chance to dig in and solve it. But with 103K miles and it being an F56 vs an R56, again, the turbo thing is definitely a side guess.

 

The R56 had a Peugeot/Renault Prince engine.

the F56 uses a true BMW motor, they don’t have intake coking problems, and turbos are
pretty good.
they go have waste gate issues at high mileage.

 

I appreciate all the help/info. I called and made an appointment with them to get it scanned. Has only had 1 half engine code then went away, didn’t stay on long enough to have read. I will let you know what I find out.
