BMW 7 (2008 – 2015) F01 F02 fuse and relay

The fifth generation of the 7 Series BMW is designated by the body index – F01 / F02 (extended version), a separate series was designated as Alpina B7. This car was produced in 2008, 2009, 2010, 2011, 2012, 2013, 2014 and 2015. This material will discuss the power supply circuit, a detailed description of the fuses and relays of the BMW F01 F02 with their diagrams and photo examples of execution. Let’s highlight the fuses responsible for the cigarette lighter.

Depending on the configuration and year of manufacture, your assignment of fuses and relays may differ from the information provided.

Passenger compartment

Inside the car, the main unit with fuses and relays is located in the glove compartment (or what I call the glove box).

It should also contain up-to-date information on the location of the fuses for your model in the form of a sheet of paper (fusecard).

Fuse and relay box

Due to the large number of consumers and control units, an additional fuse holder is installed in the luggage compartment F01 / F02. It is located on the right side under the skin.

Along with the fuses, some more relays are inserted into it or soldered onto the board.

1. Relay terminal 30B (inserted);
2. Contact 30F relay (soldered);
3. Contact 15N relay (soldered);
4. Relay for heating the rear window (soldered).
