Hi Steve I have a similar problem , mine locks but doesn't unlock on the keyfob , no pse pump noise on trying to unlock but lights flash when I press lock or unlock on the keyfob. Did you sort yours out? Cheers
Well sort of I think. Long story, but I managed to get the boot open by using the vario roof as this opened the boot enough for me to take the cover off from inside the lock and trip the boot lock open.
Then I inspected the PSE pump as most people will say this is usually the culprit. well my foam cover was dry but all 4 connectors had fairly major signs of corrosion. Thinking I had cracked it, I stupidly shut the boot only to realise that I had not put back the roof divider on its micro switch slot.
I had in the meantime tried the central locking and locked the boot again without thinking.
So I can't even get into the boot again this time.
There is a way of bypassing this boot divider micro switch and forum member Savcom has kindly agreed to help me with this to gain access to the boot again and then to sort out the PSE pump if possible.
So Rob if your keys all work in your locks you will be fine, but if not make sure you dont lock yourself out and make sure your boot divider is pulled out just in case .
Chances are it is the PSE pump. Keep us all informed please as to how you get on.
PS Whereabouts are you based Rob?
