RESOLVED - Vario roof pump stops/starts
Hi have a problem with the vario roof pump.Have searched the web for info but can find no
reference to this particular behavior.
The Vario Top open operating sequence:
1 All the side windows are lowered
2 The trunklid is unlocked and opened
3 The top is unlocked and retracted
4 The 2-piece hat shelf is raised, and
the cover sections at the sides are closed
5 The top is lowered into the trunk and
the hat shelf returns to its lowered position.
7 The trunklid is closed and locked
8 The front side windows are raised
On operating the roof switch to open or close the roof, the pump runs for approx 2-3 seconds and stops, the roof moves a few inches, continual operation of the roof switch repeats the process.
Roof switch is illuminated but not flashing. On opening the roof the operation stalls at the end of sequence 5, on further operation of the roof switch the roof appears to be pushed further into the trunk but it cannot as it is bottomed out. Sequence 7+ 8 never completes.
Complete closing of the roof can be accomplished with repeated operation of the roof switch, however now
the front windows cannot be raised by roof switch or window switches.
Have checked fuses, battery voltage, pump relay, door and trunk switches, switch s69/11,pump fluid and leaks.
Any info on why the pump keeps stopping and why the windows do not work?
