Bipper fuel level sensor fault

That sounds like a pain! I had something similar with my old car (different make), and the fuel gauge was all over the place before the check engine light even came on. It could be the sensor itself is faulty. Fuel level sensors basically measure the amount of fuel in the tank and send that info to the fuel gauge and the car's computer. Is your fuel gauge acting weird at all? Like fluctuating a lot, or showing the wrong amount?

The fuel gauge seems normal, consistently indicating the correct level. Knowing that the sensor might be faulty, could it really cause the engine to stall? Also, how difficult is it to replace the fuel level sensor, or would it be better to leave it to professionals?

Okay, consistent fuel gauge reading is interesting, but doesn't totally rule out the sensor because it could still have an intermittent fault only the computer detects! And yes, a faulty fuel level sensor CAN make the engine stall because modern cars rely on that info to help manage fuel mixture. Now, replacing the sensor...it can be a DIY job, but it involves accessing the fuel tank, which can be a bit messy and potentially dangerous. Honestly, given the stalling and the consistent error code, you might save yourself some headache by taking it to a workshop. They can diagnose it properly and replace the sensor safely.

I appreciate the input; your advice proved extremely helpful. I took it to the workshop; indeed, it was a faulty fuel level sensor, and they sorted it out quickly. It came down to a defective sensor with a replacement cost of 52€ including labor. Thanks again for the help!
