BMW 5 Series E61 / 3 Series E91 Remote Central Locking Not Work Diversity Module Receiver Wiring Fix

- Опубликовано: 26 авг 2024
- Here we have a very common fault on the BMW 3 series (E91) & 5 series (E61) - The remote controls for the central locking not working although batteries & fuses are all ok, no fault codes are logged in the car - The fault is usually either the remote receiver or 'Diversity module' as its commonly called which is fitted under the rear spoiler, is either water damaged or in most cases the wiring loom in the rear hatch has got some broken wires at the hinge point - Here we show a common fault area & repair. this may also be common on other BMW estate cars / hatch backs which have the diversity module fitted here.

Thanks for your clear explanation about the wire harness. I had only 5V on 3rd wire, but no 12V on 1st and 4th wire. All the fuses were good. I traced it back to one broken wire inside the rubber harness area (top right corner as you look from rear of car). I soldered an extra inch of wire to connect it up again (give it some slack😊). Remote locking/unlocking all working again. No more alarm going off everytime I unlock to get into the car! Yay! Cheers. 👍
Thanks for watching, and your comment.. glad it was helpful!
I really appreciate these BMW diagnostic and repair videos. It is very handy as these are the more common, less spoken of quirks with owning these cars. Keep up the videos great work!
Cheers from the USA!
Thanks for watching & for your comment! It really motivates me to make more videos!
Thanks. Save my day with the fuse suggestion.
Thanks for watching & glad it helped!
Thanks for your advice, I have the same problem but I will use a flexible cables instead
Thanks for watching, yes it’s important to use flexible cable whether it is secondhand or new - there is some good quality multi strand cable available but quite hard to source..
Thank you for a great video! On my 2009 E61 the remotes (keys) stopped working, so I had a new set made. That did not solve the issue and I took apart the "diversity module" and found no obvious damage. I'm dreading this possibility - that the cable is cut somewhere under the lining. On the plus side, my lining is half-off anyway because I was search for the reason of flooding through the sunroof (stupidly enough, the rear outlet tubes were clogged and water just overflowed the inner rails and flowed over the roof liner into the battery compartment, and, what is worse, the spare wheel space which is crammed with computers and relays - yay!)... Anyhow, I'll give the cables a good look and hopefully I can reconnect the broken ones using some scraps...
Thanks for watching & your comment! Glad you found it useful & good luck with your repair!
How did it go?
I have the same problem on my e61 will in vestigate cheers for the tutorial
Thanks for watching, glad you found it useful & good luck with your repair!
Justin. Watched this other night. What a mission on the 5 tourer. I’ve an out of date Peugeot 206 on a very low mileage in the trade with faulty central locking. Not usually a problem. Just sell it as to lock manually car under £1500 car. But this one was unlocked boot as arrived but on latch. Now it’s a locked boot. No external boot key lock and now locked shut. So Opened manually and forced to stay open by removing bar on electrical lock. As it’s failed central locking this is a screwed up car. Either locked shut boot or boot unlocked off latch !!!! What with the car being uneconomical to throw more money at. The car doesnt lock. Or unlock. This isn’t a module this time but a failed CLocking system. Sold a lot cars over the years but one like this have not. Loose on the latch open boot or locked shit. Google confirms same. System down electrical lock boot no boot key ‘you’re in trouble’
Yep, good ol’ French electrics.. probably one to clean up & send it to auction, no comebacks & prices are high there atm!
@@JC-ECUConnection Don't I know !!!
Did this on my e61 myself two months ago, caused much consternation! However it resolved the remote locking issue but the HRW still not working even through I soldered that cable too.... I live live without the hrw for now, it's nearly summer here in the UK! This is a stupidly complex design again from bmw, unnecessarily complex.
Thanks for watching & good luck!
Thank you very much✔
You’re welcome & thanks for watching!
Helped a lot thanks very helpfull ❤
Thanks for watching & glad it helped!
My central locking packed up today. The fob is fine so im guessing its the same issue. Rear wiper and heated rear acreen packed up too. Randomly, so did the journey computer from the i drive screen at the same time as the central locking. Guess im gpnna have to bite the bullet
Yep, it’s a chore to do but we’ll worth the effort, my advice is take your time & make a nice thorough job of it, there is also another section of loom next to the one at repaired here, this is worth inspecting at the same time… good luck!
I'm tackling it tomorrow. I noticed there's more than 1 brown wire in that loom. If they've all snapped how do u work out which one is which?
And do you disconnect the battery before attempting
@@davidbriggs239 try your hardest to match the wires by visually assessing the break marks, this is usually quite obvious..
@@davidbriggs239 No, no need to disconnect battery in my opinion..
Thank you for your help on this video. where are you located to bring my E61 to you ?
Hi, we are based in Norwich - for more information about us & to book an appointment please visit our website: www.ecuconnection.co.uk
I have e91 and I have a problem with low range ,i need to put key on hatch to unlock or lock ,battery in key is good no warnings on the dash
This could be the fault here, a thorough check with a Diag tool will show more..
I've been watching various videos as my F10 5 series keeps having issues with the key (I think it's a leak as it stops working after a car wash or rain)... But I'm curious, how does this even happen? Seems odd for so many wires to randomly break.
Hi & thanks for watching, I’m not sure about the faults with F-series, the fault in this video is relevant for E-series - maybe it had the same layout & issues.. the main problem with the E-series is that the repeated opening & closing of the boot cause the wiring to flex & gradually work harden & then break, also the pvc on the cable degrades making things worse & allowing water ingress.. good luck finding your fault & feel free to post here what you find!
thatbis problem on all wagon series, an radio antena is there
Yes indeed it’s very common…
Hi,
I've the same problem and more. I had some broken wires. I repaired them and bought used module cuz mine was with severe water damage. Now the remote works, but only if it is in very close proximity to the antenna in the spoiler.
I've BMW E61 530d 2007. Can you suggest a way to fix it. Is it the module in your opinion?
Thx in advance :)
Hi, it could be that the module you have purchased is faulty but I would start by testing the remote batteries, they are soldered to the circuit board & will need cutting open & soldering skills to replace..
@@JC-ECUConnection Hi. Thanks for you reply. I've changed the battery before testing. That is the first thing I did. The module was tested on another car and had no such problem. :|
@@petarbutrakov315 antenna amplilfier probably if it works close only.
Hello my friend. Which kind of scanner do you used??
Hi, we use various different scanners in our shop, I believe on this video we used an Autel MS909, we usually use either Autel or ThinkCar tools, if you are interested in purchasing a good diagnostic tool click on the link below:

I had the same problem with my E61 , all the wires was cut off , I weld all of them but still not working , the tailgate work fine but the alarm not , do you know what fuse is to central ? I change the 5amp “ you show in the video” but still nothing! Many thanks
Hi, as far as I could see the only fuse was the one in the video, have you checked the remote for a signal?, these can also be faulty - they have soldered on batteries & button faults, if not the remote then the diversity unit itself can be faulty (usually water ingress)?.. or more wiring faults further into the roof panel as in the video.. good luck & thanks for watching the video!
@@JC-ECUConnection For future ref - There are more fuses behind the glove compartment that can also be blown by this fault
Hi, what sort of price would that be to do this exact job? Thanks
Hi, for an auto electrician to do this job it should cost around £150 - £200, it’s very labour intensive!
@@JC-ECUConnection Thanks
What autal scanner are you using here
That is the Autel Maxisys MS909..
🤞🤞🤞
jesus man. nails. clip them its so hard to watch your hands
😂 Yeah, ok - got me there!!
in the past month I've had central locking failure, parking sensor fault ( not a simple fix have to remove the whole rear bumper just to change it) and now it's on its arse with the self levelling rear air suspension fault... what a piece of junk.
Yep, they’re nice when they’re new, lots of work when they’re old!
