Mini Cooper Diesel Engine Stalling Issue

The engine stalling and check engine light, along with the error code, definitely point to a fuel delivery issue. I had a similar experience with my older Volvo – though it was a petrol engine. A faulty sensor can cause all sorts of problems. Have you checked the wiring harness and connector to the fuel sensor? Sometimes a loose connection can mimic a faulty sensor. The fuel sensor is located inside the fuel tank and detects the fuel level. Another thing to consider is whether the sensor is sending the correct voltage to the ECU (Engine Control Unit).

Thank you for the reply. I note your comment about checking the wiring. Where is the fuel sensor located, and how would I go about testing the voltage?

The fuel sensor is located inside the fuel tank, usually attached to the fuel pump assembly. Accessing it usually requires dropping the fuel tank or accessing it through an access panel, if your Mini has one. Testing the voltage requires a multimeter. However, given that you suspect a defective fuse and are experiencing stalling, I would recommend having it checked by a qualified mechanic. You might cause further damage.

I appreciate the insights. It turned out to be a defective fuse related to the fuel level sensor. Replacing it, at a cost of 52€, has resolved the stalling and cleared the error. The fuel gauge on the car dashboard is now operating as expected.
