Please replace hydraulic cylinders only in pairs, not single ones!

If you replace only one single new or refurbished part, there might be an oblique movement in the roof shell, that should be avoided and potentially can destroy the roof.

The solenoid replacement seems to be very curious from my point of view. There is no exact 1:1 relationship between these solenoids to a roof module!


Opening while driving slow(!) is not an issue even with the models before spring 2012. Your issue came up though you didn't use this option.
