Mercedes-Benz Vito III W447 (2014-2022) – fuse and relay box

Diagrams of fuse and relay boxes – Mercedes-Benz Vito W447

Applies to vehicles manufactured in the years:

2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022. 

The electrical fuses in the vehicle are used to disconnect damaged electrical circuits. Activation of the fuse causes the switching off of the components connected to the given circuit and the disappearance of the appropriate functions.
Blown fuses must be replaced with fuses of the same parameters as given in the following lists. The fuse parameters can be identified by the color and the printed ampere numbers. Advice in this regard is provided by all professional services.
If the new fuse blows again after inserting it, have the cause of the fault determined and rectified by a specialist workshop.

Fuses and relays are located in various fuse boxes:

  • Engine compartment fuse box (PDC-E)
  • Fuse box in passenger footwell (PDC-P)
  • Fuse box in passenger footwell at the A-pillar (PDC-F)
  • Rear fuse box (PDC-R)
  • Pre-fuse socket next to the starter battery in the right-hand front seat box
Have the fuses in the pre-fuse socket and relays in the fuse boxes replaced by a qualified service center.

Before replacing the fuse

  • Apply the parking brake.
  • Vehicles with automatic transmission: Place the transmission in position  P .
  • Vehicle with manual gearbox: Engage neutral position.
  • Switch off all electrical consumers.
  • Turn the key to position 0 and remove from the ignition.

Fuse box in the engine compartment

  • Opening: Open the bonnet. When opening the bonnet, follow the safety instructions in the vehicle’s operating manual.
  • Use a dry cloth to collect any moisture from the fuse box.
  • Open the clamps 2 and remove from the fuse box.
  • Tilt the cover 1 in the upward direction of the arrow and remove it.
  • Closing: Check that the gasket is seated correctly on the cover 1.
  • Hook cover 1 at the rear and lower it.
