Thank you for the help on this.
I do indeed have a switch on my dash to close the doors, why didn’t I think of that.
The function of holding the key in the open position for about two seconds however does not work.
I believe there should be a comfort module fitted to have this feature and I don’t seem to have that.
I will have a look at the oncoming holidays and I will let you know how it went.
Thanks for your help.
