AUDI A3 2.0 PREMIUM PLUS 2020 Quattro Last time, the car stalled with two bars on the fuel gauge. I thought it was an engine problem, but it turned out there was no fuel in the tank, even though the gauge showed two bars (virtual cockpit). I removed the rear seat and the tank cover, thinking the float was stuck. It turns out the float is working normally, but there's probably another one in the second tank compartment (the car is a 4x4 and has a dual-compartment tank). There's a second cover under the rear seat on the left side, but there's no inspection hole for the tank. Three wires run from the tank cover inside the tank to the other side, and after disconnecting them, an error message appears on the display, suggesting there's a second fuel level sensor there. How do I get to it? Has anyone removed this type of tank and know what it looks like? I've seen several online, and some have a second inspection hole. Unfortunately, mine doesn't.
