Mini Roadster Diesel Overheating Problem

Overheating and a check engine light? Sounds familiar! I had a similar issue with my old sedan. The radiator fan was acting up, and it turned out to be a faulty sensor. Is the fan blade spinning at all, or does it seem like it's stuck? Have you checked the coolant level in your car radiator?

Interesting! The fan blade does spin, but it seems like it's not consistent, and the engine cooling is not working efficiently. Where was the sensor located in your car, and how difficult was it to replace?

Ah, inconsistent spinning is a telltale sign! On my old car, the speed sensor was the culprit. Honestly, I didn't tackle the replacement myself. I'd recommend taking your Mini to a trusted mechanic to diagnose the exact issue. It could save you a lot of time and potential headaches. It might be a defective speed sensor.

Just wanted to update you you were spot on! Took my Mini Roadster to the workshop, and it turned out to be a faulty speed sensor causing the radiator fan to go haywire. They replaced it, and now the engine cooling seems to be working perfectly. The car overheating issue is gone and the check engine light is off. Total cost was around 250€. Thanks a bunch for your help!
