In this guide, we'll explain the location of the fuses and relays in the BMW 3 Series E90 (2004 – 2013).

In this guide, we will try to figure out where the fuses and relays are located on BMW 3 series E90 generation cars (2004 – 2013).

On different models, the list of fuse locations may differ slightly, we present diagrams of the most common modifications of the BMW 3-series.

The fuses are located in three locations:

Rear power distribution panel (high amperage fuses);
Fuse box in the glove compartment;
E-box engine electronics module;

Rear Power Distribution Panel

Battery safety terminal (BST)
Line to B+ junction, starter and alternator
Line to engine electronics
Line to IBS electronics
Line to junction box
Battery sensor (IBS)
Battery ground cable
High amperage fuses (fusible links)
Housing
High current connector

Fuse Box in the Glove (Passenger) Compartment

How to get to the relay and fuse box in the glove box:

open the glove compartment,
turn the two clamps,
and remove the cover.

Under the protective cover you will find a relay and fuse diagram specific to your vehicle. We recommend that you primarily follow this diagram.

How do I check the relay?

The easiest way to check the relay is to replace it with a known working relay.

Relays are usually checked in this way at service stations. However, it is not always possible to quickly get the right relay at home, so we recommend the following way to check the so-called working relays, which include, for example, relays for the main and fog lights:

Remove the relay from the connector.
First check with a probe whether voltage is present at pin 30 of the relay’s connector. To do this, connect the tester to the ground and touch pin 30 of the connector with the tester lead. If there is voltage, the tester LED will illuminate. If the LED does not illuminate, find and repair the break in the circuit between the positive terminal of the battery and pin 30 of the relay connector.
Make a jumper from a piece of insulated wire by stripping the ends
Using the jumper fabricated, connect pin 30 of the relay connector (where the battery voltage is permanently present) to pin 87.
If the corresponding circuit closes when the jumper is installed (e.g. high beam comes on), then the corresponding relay is in good condition.
If the circuit does not close (e.g. the high beam still does not come on), find and repair the break in the circuit between pin 87 of the relay connector and the corresponding consumer.
If necessary, install a new relay
