Hi Nicola and welcome to OSM.

Note the warnings in your edit set "warnings:impossible_oneway:highway" & "warnings:outdated_tags:incomplete_tags". You've created impossible routing for vehicles with a smalll driveway at the end... you can get in, but not out. 

Also please explain the deletion of this way.

It exists, however it may appear to you, people use it as a shortcut.

Anyway, I've restored to path/access way to houses and removed the oneway tag.

Let me know
cheers
