Mini Paceman Gear Selection Display Problems

That sounds like a classic symptom of a failing control unit. The gear indicator relies on signals from various sensors and the transmission control module. When those signals become erratic or disappear, the instrument panel throws a fit. Does the car dashboard show any other warning lights along with the gear indicator issue? Have you tried scanning the car's computer for error codes? A generic OBD2 scanner might not pick up transmission-specific faults, but a more advanced scan tool should give you a better idea of what's going on. I wonder if it could be a simple sensor problem?

Thanks for the reply. Yes, the error memory does store an error. You are right, my cheap OBD2 scanner cannot read transmission-specific faults. Is there a way to test the sensors myself before I reluctantly take it to the workshop?

Unfortunately, without specialized diagnostic tools, testing the sensors directly can be tricky. You'd need access to wiring diagrams, a multimeter, and the knowledge of what the expected voltage or resistance values should be for each sensor. The error stored in the error memory suggests the control unit is indeed the culprit, as it processes the signals from those sensors. Given the symptoms you're describing, especially the shifting problems and noises, it's unlikely to be a simple fix. The electronic display malfunction is a common symptom of a failing control unit. A workshop will have the proper equipment to diagnose the problem accurately and replace the faulty unit. I'm afraid going to the workshop is unavoidable.

Thanks so much for the insights. It does seem I have no choice but to take my Mini Paceman to the workshop. They confirmed the control unit is faulty and needs replacing. Costly repair, but at least I know what's wrong now.
