Since you've replaced multiple components, consider checking the throttle position sensor (TPS), mass air flow (MAF) sensor, and coolant temperature sensor, as faulty readings can trigger limp mode. Also, inspect for vacuum leaks, transmission issues, or wheel speed sensor errors. Try resetting the ECU by disconnecting the battery for 15 minutes. If the issue persists, an OBD2 scan may pinpoint the exact cause.

This forum leans towards the classic mini. Might have better luck trying over here. https://www.northamericanmotoring.com/forums/

I have a 2008 JCW sidewalk edition convertible. The car stump is stuck in limp mode. I’ve tried everything change the alternator,the battery, pulley, spark plugs wires,O2 sensor, harmonic balancer. Nothing seems to work. Does anyone have any suggestions?
