Fuel gauge question
Hi everyone,
I recently just installed my new turbos but now my fuel gauge gets stuck at 1/2. When I fill up, the gauge goes all the way up and it continues to go down normally until it reaches the 1/2 mark then just stops. It took me a while to realize (Just thought I had some good gas mileage lol). When I turn the car off my gauge goes down so I’m assuming it’s one of my floats. Any other opinions what it could be? Thanks ![]() |

The fuel level senders are wired to the JBE Module. INPA/ ISTA, or a Scan Tool that can read Signals received by the JBE Module will show the individual fuel level signals from each sender. Then you can check the wiring from that "Half" of the tank and see where the issue is, such as short-to-ground on ground side of Right-Tank Sensor. I'll attach an ISTA ScreenPrint of 2008 335i circuit to Next Post, along with Connector View of X14271 (Blue JBE Connector). George |
