Carefully release 2-pin connector -arrow- on fuel gauge sender II (left side of vehicle) and unplug.
Warning!
The fuel tank must not be more than 1/4 full when removing fuel gauge sender II. Otherwise a large amount of fuel will escape.
Unscrew locking ring (left side of vehicle) using spanner for fuel gauge sender unit 3087.
Carefully pull fuel gauge sender II a short distance out of fuel tank opening together with seal.
Unplug connector for fuel gauge sender I on inside of flange for fuel gauge sender II.
Reach into fuel tank and release retainer tabs -arrows- below suction jet pump -2-.
Note:
The sender is shown without the fuel tank for a clearer illustration.
Installing
Install in reverse sequence; note the following points:
Note:
Do not bend arm of float of fuel gauge sender when installing.
Connect plugs and insert fuel gauge sender II (-1-) into fuel tank.
Fit suction jet pump -2- inside fuel tank onto fuel gauge sender II. Retaining tabs -arrows- must engage.
Fit new seal for fuel gauge sender II in fuel tank opening (seal should be dry).
Note fitting position of fuel gauge sender II:
Marking on sender -2- must coincide with marking on fuel tank -1-.
Tighten locking ring (120 Nm).
Fit cover for flange so that the projecting part is above the electrical connector.
Notes:
When the battery is reconnected, re-activate electrical equipment (radio/radio and navigation system, clock, electric windows) as described in the Owner's Manual.

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
