P0463 on a Volkswagen: Causes, Fixes & Repair Cost

🟢 Low severity · drivable

Safe to drive, but the fuel gauge may be wrong — track your miles or fill up often so you don't run out of gas.

What P0463 means on a Volkswagen

On a Volkswagen, P0463 means the fuel level sender is sending voltage that's too high, so the computer reads a full tank. The sender sits inside the fuel pump module on most VWs, and its resistor strip wears with age and mileage. The engine runs fine; the gauge is what reads wrong.

Is P0463 common on Volkswagens?

P0463 shows up on higher-mileage Volkswagens like the Jetta, Golf, and Tiguan. Sender wear is the usual cause, and the fuel pump module must be accessed in the tank to replace it. It's a gauge issue, not a drivability issue.

Commonly reported on: Jetta, Golf, Tiguan.
