Skoda Praktik Stalling Fuel Sensor Fault

Okay, that's a tricky one. The stalling at idle coupled with the fuel sensor error definitely points to a fueling issue. First, is there a specific code number associated with the check engine light? That would help narrow it down. Have you checked the wiring to the fuel level sensor itself? A loose or corroded connection could cause intermittent readings. Also, does the fuel gauge read erratically or is it consistently wrong? Considering the car electronics involved, have you considered a possible issue with the ECU? It's a long shot, but a faulty ECU can throw off all sorts of sensor readings. Finally, and perhaps obviously, is the fuel filter clean? A clogged filter could starve the engine at idle.

Thanks for the detailed response. The error code is P0460. I haven't checked the wiring directly – where exactly is the fuel level sensor located on a 2009 Skoda Praktik? And how would I go about testing it? Regarding the ECU, I'm not sure how to test that myself. Is that something only a workshop can do?

P0460 confirms the fuel level sensor circuit malfunction. Okay, so the fuel level sensor is usually located inside the fuel tank, often attached to the fuel pump assembly. You'd need to access it, which usually involves removing the rear seat or accessing it from underneath the car depending on the Praktik's design. Testing it involves checking the voltage and resistance across the sensor's terminals with a multimeter. A workshop would definitely be better equipped to diagnose an ECU issue, as it requires specialized tools and software. Given your symptoms, it might be worth a visit to a workshop, or at least consider checking all the fuses related to car electronics and the fuel system. It is hard to say, but it might save you a lot of headache.

Just wanted to say it was a defective fuse linked to the fuel sensor. Replaced it and the car runs perfectly now. Total cost was 52€. Thanks for pointing me in the right direction.
