BMW 7 (2001 – 2008) E65 E66 fuse and relay

The fourth generation of the 7 Series BMW was produced in 2001, 2002, 2003, 2004, 2005, 2006, 2007 and 2008 under the E65 body design. E66 – designated a longer version of the car, and E67 – armored versions. During this time, the car went through one restyling. We offer information describing the fuses and relays of the BMW E65 E66, block diagrams and their locations. Let’s highlight the fuse responsible for the cigarette lighter.


The purpose of fuses and relays may differ from those presented and depend on the year of manufacture and the level of electrical equipment of your car.

Passenger compartment

Inside the car, the main box with fuses and relays is located behind the glove compartment or, as it is also called, the glove box.

Access to fuses

To access, push the cover tab forward and flip up. It will look something like this. fuses in the glove compartment

At the bottom there should be a fuse data sheet with up-to-date information for your model. We offer only general information. Spare fuses and plastic tweezers are located on the mounting block in the trunk.

  • Your webaddress is called yet I haven’t seen any mention of the relay locations and assignments for the BMW E65/E66. I know there are relays as I have seen three. Two by the trunk power module and one behind the fuse panel behind the glove box. Knowing he locations and assignments of all relays would be extremely helpful when troubleshooting issues such as air conditioner suddenly stops blowing cold air. Kinda difficult to follow process of elimination on compressor clutch function when the electrical components controling power to the clut h can’t be located.

  • I have a 2004 BMW 745 LI I have been teaching for the starer relay everybody saying that it’s located by the computer under the filter I did remove every devices there and that relay is nowhere to be find I can only see 2 relays in the trunk by the fuse box and 1 under the gloves compartment
