Original BMW Left Fuel Level Sending Unit for BMW E46 3 Series 323, 325, 328, and 330 (1999–2006)

The Original BMW left fuel level sensor, part number 16-11-6-768-788, is the sending unit in the left (driver side) of the fuel tank that reports fuel level to the gauge on E46 3 Series models from 1999–2006. A sender of this type uses a float on a metal arm that moves across a variable resistor, so the signal to the gauge changes as the fuel level rises and falls. BMW records this unit at 223 g (0.5 lb), and production of this number began in May 2004. Each sensor comes with the fuel tank seal O-ring, part number 16-11-1-184-084, and it is made in Germany.

Original BMW Parts carry a 24-month parts warranty.

This number replaced an earlier BMW part, 16-11-6-755-879, and BMW marks the change as exchangeable retrospectively. That makes the current sensor the correct replacement for E46 cars built before May 2004 as well as for later production. The part also cross-references to 16-14-6-755-879, 16-14-6-752-192, and 16-14-1-184-281, so a car that left the factory with one of those numbers takes this sensor today. Because the tank seal O-ring is packed with the sensor, there is no separate seal to order for the tank opening.

Common Questions

What signs point to a failing fuel level sender?
A worn sender can leave the gauge reading full, reading empty, or swinging unpredictably. The gauge may also stick in one position or read empty while fuel remains in the tank, and a gauge that shows no fuel reading at all can trace back to this part.

Does it come with the tank seal?
Yes. Each sensor includes the fuel tank seal O-ring, part number 16-11-1-184-084.

My 2000 328i came with 16-11-6-755-879. Will this sensor fit?
Yes. BMW marks 16-11-6-768-788 as exchangeable retrospectively for that earlier number, so it is the current replacement for your car.
