Ok, this is for a 2013 Mini Cooper S. If I drive without pushing it she runs fine. If I hit the accelerator to try to pass or just get moving quick the engine stutters and goes to half power with some stuttering sounds and the half engine light is lit.

I've taken it to the local Flow Mini dealer to have this fixed...twice and it still happens. The first time they "fixed" ignition coils. The second time they said my oil cap was on upside down. That made no sense.

Any help you could give would be appreciated!

 

Could be a zillion different things. Get the code(s) pulled and post back..

 

Yes, gonna need much more info like stored fault codes, mileage etc...

 

+1 get the codes and if you need code reader get this one.

I have a 2016 countryman, jerking with the Half engine yellow light and check engine on. The pulled out DTC is 2C72: Boost Charging pressure sensor, plausibility, after-run pressure too low.The sensor was changed but to no avail. Any clue that can help?
