Information 

Before replacing the high-pressure pump if you suspect that it is faulty, check the performance of the fuel pumps in the tank. (Low-pressure test).

  1. Pull out the use for the fuel pump. This ensures that the fuel pump will not start up when a door is opened. Fuse box at right of dashboard, slot 47.
