T6 Central door locking not working from the inside

[Devindb]

I have a T6 from 2018. It's not locking by use of the button on the drivers door, however it is unlocking by using the unlocking button over there. The doors are opening and closing by using the key fob. Checked the fuse (only one 5amp?) and all ok. What could be the problem?
Thanks!

it will be the microswitch inside the door control unit. Mine has failed too.
You can remove the unit and remove the blue microswitch from the rear and probably see like mine that there is corrosion from water ingress.
I've just removed mine but not yet ordered a replacement as everything on ebay looks like copy chinese stuff.
the blue microswitch is the same across many VW's such as passat etc.

This is it, but you just need the blue part.

Got a pic of the button that's not working?

That's it, just removed the microswitch and there is corrosion on it. Will order the microswitch on eBay
