These are only rumors. There was never mounted a "better" mechanism in the car. Quality is the same on all cars from 2009 up to 2016!

The only difference is a 4th hydraulic valve on the hydraulic pump as of 2012. It forces the hydraulic pressure to open/close the roof while driving, as this was offered since spring 2012. The "newer" harness got a new part number as 2 additional wires were added from the CTM to this 4th valve.

No.


Pse apologize, but my expectation from 2 dozens of examined and repaired E89 roofs is, that all hydraulic hoses of this roof shell will break at the age of 10-12 years.
