How can you tell if a fuel pump relay is faulty?
The relay switches the fuel pump(s) depending on engine speed and switches them off when there is no speed signal – if it is defective, the pump can no longer be controlled reliably, which can result in starting problems or the car being stranded. Since the relay also controls the cold start valve during starting, starting difficulties can also occur here with a cold engine.

⚠ Important: compare the part number before buying
Mercedes changed the KPR of the 6-cylinder W126 several times (including 002 545 27 05, 002 545 51 05, 002 545 92 05/93 05, 003 545 16 05/17 05, 003 545 23 05/24 05) – depending on model year and cut-off speed. Our end number is 002 545 51 05 (A 002 545 51 05), build level 08/1986 – 08/1988. Please match the number on your old relay 1:1.
