I think the actuators are sold in sets of 2 and cost around R800 for the set :thumbs:

E90 Drivers Door Won't Lock

Thread revival,
My 2012 320d passenger doors front and rearwon't lock with the remote but will unlock if locked manually. The drivers door locks and unlocks normally. I haven't checked the fuses yet. But it's weird that it unlocks but doesn't lock.

Actuators need to be replaced.
They work off 2 separate motors for opening and closing.

The main issue, if you open an actuator up, is most of the moving parts that take a huge amount of force and impact are plastic. The toothed gears suffer constant torture for as long as they can and then a piece breaks off rendering the locking or unlocking process impossible.
I tried rebuilding one or two but it never works. The last time I tried to get replacements from BMW they mentioned they old special but the prices nowadays are exorbitant.
Best thing is to watch a YouTube video on how to remove the lock then take it with you and go to a second hand spares place and pick one up. You need to make sure the replacement one matches exactly - you get 5 pin and 7 pin ones I think. Then watch the rest of the video as you reinstall.
It is finicky and you need deft fingers and bendy wrists - as well as a lot of patience.

Is it possible for 3 doors to go all at once?

That does seem suspicious but surely the FRM and related fuse control all four doors so they would all go at once not just three?
I have had three of mine go just at different times.

It is baffling. The Front door lock works as per normal.

Common failure with E90s due to age,I had my driver's side door actuator fail and the guy that tried to fix it broke my key cylinder so I had to fix it with the door closed.... You should make sure you buy the correct door actuator for right hand drive models,no point in trying to repair the old actuator6 years later and the drivers door now does this
