XC40 Fuel Level Sensor Fault

My 2019 Volvo XC40 hybrid with 161496 km is showing a fuel level sensor fault. The check engine light is on and the engine stalls at idle sometimes. The error code points to the fuel level sensor. I've checked the fuel cap and wiring, but no luck. Could it be a fuse, or is the sensor itself bad?

Summary of the thread

A 2019 Volvo XC40 hybrid with 161,496 km is experiencing a fuel level sensor fault, causing the check engine light to illuminate and the engine to stall at idle. The issue is likely due to a faulty fuel level sensor, as indicated by the error code. After checking the fuel cap and wiring without success, it is suggested that the sensor itself may be defective. The recommended solution is to have a mechanic replace the faulty sensor, which resolves the problem.

I had a similar problem with my old BMW 3 Series. Same symptoms: check engine light, occasional stalling. It was a faulty sensor in the fuel system. Have you checked the wiring harness for corrosion or damage?

Thanks, I inspected the wiring quickly, but I'll check again more closely. When you say 'sensor in the fuel system,' was that specifically the fuel level sensor, or something else affecting the fuel mixture? Did you fix it yourself or go to a mechanic?

Yes, it was the fuel level sensor. You could replace it yourself, but accessing the fuel tank can be tricky and dangerous if you're not experienced. Given the symptoms and error code, I'd suggest a workshop. They can diagnose it properly and ensure a safe repair.

I brought the XC40 to my mechanic as suggested. The fuel level sensor was faulty. It was a straightforward fix; the new sensor and labor cost 52€. Thanks for the help!
