Hi kingz4
I am in Newport where are you?
We have a small group of Z3 and Z4 owners in and around South Wales and some members across in Bristol that keep in touch and get together as a Zed Shed Cymru Group when we need jobs doing on our cars. Usually meet up at my home garage as I have a car lift.
Owner supplies parts and between us we do the job, donations towards consumables and tool fund are down to the individual whenever a job is done.
We keep in touch via a Whats App Group which you are invited to join, you will need to send me a text to be added in. I will send you a PM on here with my contact number.
As to your key fob lowering the roof, try holding the unlock button down for a longer time and see if the roof opens. If it dosn't the car may need to have the comfort access file amended using NCS software on a laptop to set the option for roof opening from the fob. I have NCS Expert and could plug your car in to see if it needs the option selecting. This can be done with the Carly system but its quite an expence to get it and there is a subscription to pay to use it. I have Diagnostic software on a laptop and a Creator 310+ handheld scanner should you need to code read your car for faults when dash lights illuminate. The Whats App group is useful for listing any run outs and car shows we attend throughout the year as and when they take place.
