Fuses, i'm gonna blow one

Post by sapphireblack » Thu Sep 25, 2025 1:54 pm

Fitted a dash camera today and disturbed fuses front and back and obviously got some self-inflicted hassle refitting them.

I'm struggling to understand BMWs schematic at the rear and there isn't one at the front

Anyone with the knowledge to help me resolve these errors?

The rear camera is working but the error says not.

There should be a card above or below the front box. Usually slid into place.

Try this (I know it’s LHD) but they’re mainly the same. https://fuse-box.info/bmw/bmw-x6-e71-20 ... -and-relay

Did you disconnect the battery before you added the dash cam? If not then you could try that and see if it will all reset.

Mine often flashes up rear camera not working or certainly did with the old battery due to low voltage as it doesnt respond quick enough especially in colder weathet ,not driven it much of late as its constantly broken these days :rofl:

Thanks as ever. There is a fuse card in the rear but i find it hard to decipher, nothing seems to relate to either of the binnacle warnings.

I didn't disconnect the battery. I managed to blow one 20amp fuse relating to the rear 12v socket. It was while searching for that fuse i got muddled with positions. I think they're right, but the rear camera warning whilst it is working is a bit confusing. Maybe the infamous battery reset is the trick for the morning?

Ultimately i used a Nextbase OBD port lead for the camera power. So a re- set of the battery isnt an optimistic thought but i will of course try it.

Bettery reset didn't change anything, other than producing its usual 4x4 inactive etc message.

It looks like I'll have to delve into the fuse box again. The techie guy ive got to know suggests if there's a vacant position either side of the 20aml fuses i disturbed, fitting a 10amp fuse either side of those should narrow things down. If the new 10amp fuse blows that where the 20 amp should be. Sounds a bit Heath Robinson, but I'll give that a go over the weekend, if the weather permits it.

Worse case scenario is getting the dealer to sort it out when it eventually goes back for springs.

I am a plonker!

You are neither the first, nor will be the last to stick a fuse in the wrong slot or forget where it came from! :oops: :oops:

Reversing camera should be in F108. On your picture it’s the 5A (yellow) immediately to the right of the vertical white chalk/marker line.

Good shout x5sport :thumbsup:

I always take a pic with my fone before removing fuses , as I once removed all the fuses on my brothers passat (one by one) to try and find a broken one for a door fault and put 1 back in the wrong shot , without those pics id have had no idea where to start as there are so many different fusebox revisions on that car

BNW have jusr]t replaced my dash cam under warranty and they had not installed it onto the right fuse point (they have to add one in) meaning fault finding was a challenge. Apparently the fuse it should go into was already used in the UK. Too many variants as you say. Take a pic first seems to be a very good idea.

Hmm, now my concern is growing. I was only searching for blown 20amp fuses, correct i think for 12v sockets? If the reverse camera is a 5amp, i dont recall disturbing any of those. I'll have a search for F108 in the morning. The problem is compounded by disturbing the front fuse box as well.

And confusing as i said, the reverse camera is fine. The binnacle message is that it isn’t

I too would normally take a picture before messing, i can't believe i didn't this time :oops:

108 and 114 for the camera from what I can make out both 5 amp

111,113,115 which are the 3 x 20 amp fuses in top right of my pic ( 2 yellow ,1 brown ) and 118 which is yellow 20 amp just up and to the left from the red tweezers on its own for the 12v sockets , guessing the brown on is the one I replaced

Thanks for that.

I didn't wait until tomorrow. I seem to have sorted the camera warning with a 5mp fuse in what was one of two empty slots. By process of elimination i fitted one in each but only one is still fitted and the error is not showing. I am baffled though, as i dont recall disturbing any 5amp fuses, i was only focused on 20amp positions. And i dont have an old blown 5amp fuse. I still need to resolve the high beam assistant error, which i suppose could be in the front fuse box??

Images of the boot fuses and my key are now attached. Nothing I can see refers to the high beam assist fuse/error? Im guessing the high beam assist would be a low value fuse as well, not a 20amp?

My markers show the 20amp fuse replaced yesterday for the rear console 12v socket. The one above is the 5amp just fitted.

Whatever else i may have done, i did not pull a blown 5amp fuse yesterday? Confused for sure.

HBA works off the KAFAS camera at the top of the windscreen and is controlled by the Camera Based Assistance system (which also does lane keeping and speed limit monitoring). Its fuse is F114 in the rear. 5A. It’s two above your upper arrow (brown 5A fuse) in the same column (left side).

I’ve checked the TIS and that’s the fuse showing for the HBA/KAFAS controller - which is up front.

When you blew the 20A fuse you may have induced a fault elsewhere if a wire touched something by accident.

And no, the fuse card doesn’t have a symbol for it. Isn’t that helpful of BMW!! Same fuse regardless of LHD or RHD.
