WM 201549 Eliminating symptoms in body interior: Reworking sender for fuel-level indicator (Fuel consumption display incorrect) (SY1410)

General information

Symptom

After filling the fuel tank fully, the fuel-level indicator in the instrument cluster only shows that the tank is approx. 7/8 full. After driving a short distance, the fuel-level indicator in the instrument cluster changes to "Full" (in most cases).

Causes and remedial action

The spherical float for the right fuel level sender gets stuck at its own wire harness when filling the fuel tank.
This is possible on vehicles that were produced at the beginning of model year B (2011).

In the event of a complaint, retrofit a tie-wrap on the fuel level sender wire harness at the fuel pump wire harness.

Information

We recommend that you only carry out the required work when the fuel tank is approx. 1/4 to 1/5 full. Please pass this information on to your customers.
