e91 320d Remote central locking not working

[Origin Unknown]

Neither of the two key fobs will remotely lock or unlock the car. Well documented fault with under rated fuses (this car was manufactured 2008/01 so fuses in 76/77) - neither blown although both rated at 15amp.

Disconnected battery for 30 mins after messing about with fuses. No resolution.

Central locking button on centre console functions and can lock/unlock using the key inside the door fob. Opening doors post locking with key triggers alarm but deactivates when key inserted into dash. Both keys allow car to start.

Any ideas what next or off to the indy?

Can't edit title - its an e91 not e90.

Cheers mate. Is there a way of checking it or do I have the right symptoms to make this clear cut diversity module fault?

Changing the diversity access module did not solve the problem. Looking at the old one, there was no evidence of water ingress but I've left the new one in there for the time being.

Chances of both key fob batteries dying at the same time seem remote. It's non-comfort access so I can't open them and change these and they are supposed to recharge while in the dash.

Unsure what to do now, any ideas?

Thanks PDP76!

I can't guarantee that broken wires are the root cause. Having changed the diversity module and finding this didn't solve the issue, opening up the sleeve did expose the issue.

I fixed this, had an inspection 2 carried out and changed both rear tyres within a couple of weeks of buying it. It then shat it's timing chain almost immediately after.

Listed as spares or repair on eBay and got the original cost minus the above back on it.

The world continued to turn.

If you look at my picture above, B was the break point on mine. If you google image search the problem, it's seems reasonably consistent as the break point. Good luck.
