I have my roof stuck in the closed condition.
Last winter I discovered a flooded battery well which I dried out. The sponge was sodden. I removed the pump motor which was full of black water and cleaned and dried it. I topped up the fluid reservoir and luckily this seemed to cure the problem after a few cycles to bleed the hydraulics.
This spring I checked for water and the sponge cradle was damp, blut the motor was ok. The roof opened ok but now I can't close it. You just get the dong and the red roof symbol on the dash. I have removed and checked the salmon relays which seem to work ok. I noticed they are different pin connections from standard relays so you have to buy the BMW item
Is there anything else I can check? It's a bit difficult to check anything with the roof stuck in the boot.

My Foxwell reader shows real time the switching of roof switches or hall sensors when operating the roof.
If there's a fault it stops and you can see where it got to and the fault code comes up.
For instance i could see a salmon relay said open when it should have been closed. Replacing the relay cured that problem.
Also used it to diagnose a lack of charge problem on battery.
Just about to use to bleed abs replacing brake fluid.
Has been worth every penny of about 130 quid.

The above named concentrator K6 for the elder Z4 E85 & Mini R52 has been completed as well.
A completely new interface cable for the 14+6 pole connector had to be built as well as the BlueBox K6.
Have a look at the development process of this Y-cable:
20 wires forth plus 20 wires back
Additional 1.5mm² wires to control the motors
Voila, Germany's Next Y-Cable. 8)
Keep up the good work.

Arrgh, during a test session on an older Z4, here's what happened to my new addon interface box for the front locking systems:
Melted conductor tracks on the circuit board.
I had to redesign the complete unit and added an electronic overload protection (shunt, transistor, relay) to timely shut down this unit if a short circuit or current overload occurs on the front locking system. This additional group was placed on the left:
My test environment with 3 different front locking systems: E93 , F33, E89
