Sliding door handle?

[Tate76]

Hi, I have a mercedes vito w447 111cdi 2015 van.
The drivers side sliding side door won't open from the outside, it will open from the inside ok but not the outside. I have lubricated all the mechanisms, changed battery in key fob etc, central locking is working OK, but no result. I am wondering if its a mechanical issue with the handle to the door release if that makes sense? It doesn't open that great from the inside, it will open but it just doesn't feel quite right. Any thoughts? Thankyou !

I have a much earlier Vito, 2007 639. Fwiw the door operating system is (fairly) easily accessed when the inner door panel is removed on the 639. Furthermore the way that the handles engage on the 639 could enable precisely that fault to happen.
