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.

Power system overview
The general scheme looks like this.
- Generator;
- Battery positive output;
- Power distribution box in the engine compartment;
- Control electronics compartment in the engine compartment;
- Front fuse holder behind the glove compartment;
- Rear fuse holder on the right side of the luggage compartment;
- Accumulator battery;
- Starter.
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).
- Front fuse holder;
- Junction box electronics.
It looks like this.

Separately, we note: fuses 54, 65, 147, 176 are responsible for the cigarette lighter. Half of them are in the luggage compartment.
The relays are marked with squares: signal relay, windshield wiper relay, and others.
Luggage compartment
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.
- Relay terminal 30B (inserted);
- Contact 30F relay (soldered);
- Contact 15N relay (soldered);
- Relay for heating the rear window (soldered).
Designation
Check the purpose of the elements with your diagram or other technical documentation.

Fuse box
An additional fuse box can be installed next to the main fuse and relay box if there is an additional battery in the car.

Hello, which is the fuse for aircon fan in the boot.
where is fuse 68 located? It is shown on this helpful guide as a 40a fan, but neither of the diagrams have a fuse location 68 or even 69,70 or 71.
