Hi

I have an Edition M Sport 2008 3 Series. Inside the centre console is a cigarette lighter, never used it but now that I need it (to plug in my Bluetooth adapter) its not working.

Too many threads about this issue. Anyone know where I can replace the 20-amp fuse? I’ve tried #8 but read rumours it could also be #30 - this slot is currently empty.

Fyi the cigarette lighter at the front is running fine.

F30, 20A Which is not empty in the picture you provided..

The fuse for ALL lighters and 12V+ Power Sockets is F30 on all E9x models built BEFORE 9/1/2007, and F8 for models built AFTER 9/1/2007. I'm NOT familiar with the M3, but it appears to have a different setup, and if that's what you have, you need to go to TIS and enter the last 7 characters of your VIN to get circuit information; search "12 V sockets" EDIT: ACTUALLY DON'T use that search term as that gets you special vehicle wiring; SEARCH either: "cigarette lighter" or "charging sockets":

All Power Sockets are on SAME fuse in ANY E9x model (M3 excluded), so if ONE lighter/Power Socket works and another does NOT, the issue is NOT the fuse, but a loose or disconnected connection (either 12V+ or Ground).

I have the 2013 M3 and same problem as posted in OP. Convenient their little reference chart uses hyroglyphics to describe each fuse. My best guess is it's the no 8 fuse with the - + power logo. It's definitely fried! Will order a new one and see!
