How it works

The front power distribution box sits in the engine bay. Each row is one fuse with its rating, the terminal it is fed from (30 always live, 15 ignition, R radio position, 56a / 56b high and low beam, NSW / NSL front and rear fog) and everything it feeds.

How it works

Fuses F24–F46. A fuse that blows again straight away points to a short in one of the consumers listed: unplug them one by one.

How it works

A few options have their own small fuse boxes: the alarm (P95) and, on later cars, P97 for the four-cylinder fan and the M52 exhaust flap.

Reading the wire codes

BMW labels every wire with its size and colour, for example 2.5 SW/GE: 2.5 mm², black (schwarz) with a yellow (gelb) stripe. Connectors are numbered X…, followed by the pin. The wires in these diagrams are drawn at relative thickness, so the 25 mm² battery cable stands out from a 0.35 mm² signal wire.

Codes used here: SW = black, RT = red, GN = green, BL = blue, GE = yellow, BR = brown, WS = white.
