Product details

About this part

Part number A1665400417: a fuel level sender unit assembly that replaces the original unit on MERCEDES-BENZ GL-CLASS and M-CLASS with no drilling and no adapter.

A sender that has worn its track will read full for a long time and then fall quickly, which is the pattern that gives the fault away. The sender is a float arm on a resistor track: as the float rises and falls the resistance changes and the cluster converts it into a gauge reading.

The fitment we have confirmed runs from 2011.06 to 2015.12, split across 2 references in the table, so check the chassis code against the list before you order.

The arm length and the float position match the original part, which matters because a sender for a different tank shape will read wrong at both ends. The resistor track is a thick film printed element, which wears far more slowly than the wire wound tracks used on older senders.

A needle that jumps when the car goes over a bump is the wiper losing contact with the track. Reading empty with fuel in the tank, and a low fuel warning that comes on early, both point at the sender. A gauge that reads correctly when the tank is full but drifts at half is usually the sender rather than the cluster.

Match the float arm length to the old unit before fitting, and check the sweep does not foul the tank wall. Access is usually under the rear seat or through the tank flange; release fuel pressure before opening the tank. After fitting, fill the tank and check the gauge reads full before handing the car back. Cross reference numbers are listed with the item; send yours if it is missing and we will check it against the drawing.

The reference A1665400417 is stamped on the box, so the part that arrives is the part that was quoted.
