MINI DTC P111B (0x2B68) - Mass or Volume Air Flow via O2 (Oxygen) Sensor Too Low (Bank 1)
The ECU is seeing a too low of intake air through the reading of the pre-cat O2 sensor.
That either means the ECU is trying to adjust for a too rich of burn, or there's a downstream leak in the system.
Pressure check BOTH the intake and exhaust side of the system, making sure gaskets, and components are not venting any air to atmosphere.

Not sure if the OP is even here anymore but start simple Spark Plugs? they are overdue if not done yet, Ignition coils can go out, any misfire can cause that code.

That sounds a lot like the 'cold start rattle', but that was a timing chain tensioner problem on the Cooper S models and it looks like you have the Cooper non-S.
The P111B error code can be caused by a vacuum leak - look for leaks between the throttle body and the cylinder head....
Let us know if you find anything.

Hi,
Scan code presented P111B (Mass or Volume Air Flow via O2 Sensor Too Low Bank 1)
Car is misfiring and rough.
I have added two Youtube links with engine audio that I have recorded:
