So my roof won’t detach or go down burn it I manually put it down the button blinks red and when I close it from the controls it goes up and latches on place with no problem. I’m stuck any advice would help.

How do you add hydraulic fluid to the motor? I think my motor is good. It goes down easy, but struggles to come up

Hi, I came to your video because (surprise, surprise) I have a problem with my Z4 roof! However, I am getting no lights on the up or down control buttons. I’ve checked the fuses and they are fine. Any idea where I should start to look for what the problem is? Thanks
