Since I have had the new battery fitted , when unlocking the car doing 2 presses of the fob to do boot and all doors it’s only unlocking the driver door. If i press again all the windows open. Is this just coincidence or something to do with the new battery. Thanks

There is a bit about enabling 'Single Locking' on Page 7 of the handbook.

From what I see --- holding down Lock & Unlock buttons at the same time will toggle the function.
