==Issues - Fuse and Relay Box==
This page describes fuse boxes, fuses and relays as of W220 [[facelift]] vehicles (from 30/09/2002).
'''Quickly Identifying Fuse Consuming Units'''
The major difference in pre-[[facelift]] vehicles is that instead
of four fuse boxes (two in the engine compartment, one under the back seat, and one in the side of the dashboard),
pre-[[facelift]] vehicles have three, omitting the fuse box in the side of the dashboard.


Fuse charts for all vehicles in compact printable form are available for download in the section below.
It is recommended that you keep a printed version of the charts in a plastic sleeve with the spare fuses in the spare wheel well.

This page describes fuse boxes, fuses and relays as of W220 facelift vehicles (from 30/09/2002). The major difference in pre-facelift vehicles is that instead of four fuse boxes (two in the engine compartment, one under the back seat, and one in the side of the dashboard), pre-facelift vehicles have three, omitting the fuse box in the side of the dashboard.

Fuse charts for all vehicles in compact printable form are available for download in the section below. It is recommended that you keep a printed version of the charts in a plastic sleeve with the spare fuses in the spare wheel well.

Prefuses

In addition, there are several large fuses, 100 amp or so, sometimes called "pre-fuses" that supply power directly from the battery via large red wires to the SAMs and the fuse boxes attached to them. The "pre-fuses" are not shown on the fuse diagrams. If these are shorted, the fuse and the block that contains it must be replaced. The 100 amp fuses are not available separately.

There are two prefuse boxes in W220. X4/10 (underneath the passenger footwell carpets) and X4/22 (trunk right).

Front prefuse box (X4/10) opened.
Rear prefuse box (X4/22) opened.
