Fuel Level Sensor Issue

Hey guys, I'm having a weird issue with my 2007 Volvo S40 diesel. The check engine light keeps popping on, and sometimes the engine just stalls when I'm idling. I ran a scan, and it's showing an error with the fuel level sensor. I'm no expert, but could a faulty sensor really cause the engine to stall? I checked the fuel cap; it's on tight. Anyone experienced anything similar?

Dude, that sounds rough! I had something kinda similar happen with my Volvo S40. My fuel gauge was acting all wonky, bouncing around like crazy. I never had the stalling issue, though. Have you checked the fuses? I know it sounds simple, but sometimes it's the easiest thing to overlook. It might be fuse defective.

Okay, interesting! Where exactly is the fuse for the fuel level sensor located? And would a bad fuse really throw a code and cause stalling? I'm trying to avoid taking it to a shop if it's something simple like that.

Alright, I'm not sure about the exact location, you can find the fuse box diagram in your owner's manual. And, yeah, a bad fuse can cause all sorts of weirdness with the electronics. Still, with the stalling issue, I'd honestly recommend getting it checked out by a pro. Could be more than just a fuse, you know?

Thanks a lot! I'll check the fuses first, but you're probably right about getting it looked at. I took it to the workshop and you were spot on: It was the level sensor, and luckily, the defective fuse had not damaged other components. The repair cost me 52€. I really appreciate the advice!
