MY12 D4 HSE - Both Rear Doors Won't Open from Inside

Happy Easter Everyone.

A small issue seems to have developed with the opening of the two rear doors on my D4.

The doors open fine using the remote, from the outside and if you press the internal unlock buttons but they don't when you pull the handle on the inside without unlocking first. No resistance at all. I've also checked to make sure that the child locks are turned off.

I didn't think that this was the central locking actuator as the doors always unlock when buttons are pressed but maybe this is just the start of them failing.

Any thoughts would be greatly received.

The child lock is 'hidden' via a little rubber bung (size of a one pence piece) so it would be very hard to operate it accidentally. You need a deliberate twisting action.

I have just changed both my rear door locks (they failed to lock and unlock so not the same fault as you). One of them is out of stock and on a long lead time with LR (only fit genuine ones - eBay is littered with Chinese copies which apparently fail quite quickly) but I managed to find a brand new one for that side on eBay. Priced around £147 each Big Cry

Mine appeared to unlock (visually) and if you smashed the unlock button 10 times sometimes they would unlock! It was time to change them.

Changed them using this video.

Took me 90 minutes on one side, and after getting a bit smarter, 60 minutes for the other. Definitely a two-person job though.

But always check your model (I believe they are the same for all D4s) Whistle

Not sure if I have helped there but definitely check the child locks 'again'.

Thanks both for commenting, very much appreciated Thumbs Up

It's been like this for a little while. When I looked around yesterday I found the OSR child lock on so I thought this was the issue but unfortunately not.

I'll double check and see what I find. I agree that everything points to child locks.

Thanks for the part codes in case I need to purchase them. I'll keep an eye out on eBay just in case.

Enjoy the Bank Holiday.
