C30 Fuel Level Sensor Fault

A fuse could be the problem. What was the error code? Have you checked the wiring harness and connector to the fuel level sensor for damage or corrosion? These are common causes.

Good call on the wiring! I checked it quickly, but I'll check again tonight. The error code was P0461. Does that help?

P0461 confirms a fuel level sensor issue, but not the exact cause. Since you've checked the basics and will check the wiring again, I suggest taking it to a workshop. Fuel system issues can be tricky, and messing with the fuel tank without knowing what you are doing can be dangerous.

Thanks! I re-checked the wiring and found a corroded connector. I cleaned it, cleared the code, and the stalling is gone! The dealer wanted 52€ for a new sensor – glad I avoided that!
