Ok, so we've had a few members report problems associated with fuses.

I thought I would pull together this guide to fuses, and their functions so that any members searching for fuse related issues would arrive here in future. I've organised the thread so that anyone searching can find the specific terms. There's a picture at the bottom of this post with the fuse numbers and their relative positions

Hope you find this useful.

Fuse box access is through the glove box. Push up on the tabs shown in the circles below to drop the glovebox down fully, which will reveal the fuses....



Please advise of any errors or ommissions, and I'll update the list

Excellent - have printed this off and put in the file in my Zed for reference. THANKS

or even better this diagram - which shows the ones which are powered on ignitions or not:

Ah..... the power of the Forum.

Great posts guys

Updated with a picture of how to access the fuse box. The BMW manual doesn't do a good job of explaining how to access

Brilliant Adamski, need to refit headlamp washer fuse for MOT at end of the year so will print & keep this to oneside

Awesome Work Adamski

Good job Adamski

Very useful info guys! Keep in mind there are some differences between original and facelift versions. The fuse for the auto-dim mirror changed, as one example. Most are the same though.

Thank you guys!

Adamski

I salute you sir

This was very useful to me today when the fuse has blown to the cigarette lighter (really the tom tom power and iphone charger) and I was faced with a bank of 50 ish fuses.

15 amps Crickey I wonder how that has blown but have installed the auto roof upgrade recently. Anyone else have this problem?

Anyway thanks

are any of those empty sockets powered from the ignition? i want to hardwire my DAB into the glovebox this seems the ideal solution

I've just been looking at this to figure out what fuse is best to tap into to power a hidden bluetooth music streaming dongle thing and ended up putting this spreadsheet together of which items relate to which features. Thought it might be of use to other people, so here are some links to it as .xlsx and .pdf

Edit: the links stopped working from Google drive due to changes with the security for links, so here’s an image for now and I’ll upload the originals again soon.

Super useful, as my fuse chart was missing. Thanks a lot for this.
