Thanks everyone. I'm just about to go on a search v-power so wish me luck.
Thanks for info regarding the door lock. I've just noticed that if I press the little black button, it unlocks fine so can't be sticking like first thought. I will try the reprogramming to get both doors unlocking with one press and report back.
I've cleaned her up also so some pics up tomorrow
tried snow foam for the first time and am impressed
