i bought my Mini on May 21st and i went right to learning as much as i could about it. i browsed these forums and come across several threads on the fuses. so, went out and looked at mine and found that i was missing 2x 50 amp fuses under the hood. one went to the engine cooling fan (FL9) ahe one with the engine with a bolt of electricity through it (FL7).

i put 2 new fuses in and noticed the cooling fan come on and it is fairly loud.
i have no idea what the FL7 does.

i found a couple of posts that had a legend for what fuses does what, but did not match, like someone said FL7 feeds to the ignition, well my ignition works just fine with the button.

 

This is from another post, which was for 1st gen MINI's, but may be helpful.

i had already saw this. I'd like to find an updated legend for the image of the fuse diagram i posted.

 

Did you happen to find an updated legend? Mine is like this also and I've been able to find nothing. Trying to figure out why my 7.5A F7 fuse keeps blowing (yet seems to affect nothing... I don't know what it's connected to in my '08 Clubman non-S)

 

Wiring diagram says Fuse F07 is connected to "Engine breather heater 1". Something to do with the oil system. It seems to be a heating element that is connected to an oil pressure relay.

Thanks so much. This is a great help!

 

Hi, I have a MINI R56 from 2007, 120 HP and I don't have relays R2 and R4, The engine is working OK, with some problems at morning start (something on electric sparks).
It is Ok without R2 and R4?
