Vario Roof Pump Fluid Overfilled
I recently had my pump, lock cylinders, and lines replaced via Top Hydrualics. Everything worked great the first few days, now the open/close movement is slow to partially stuck at times.
I read a few threads about how to address a potential air bubble, followed that and everything worked great until the 3rd close attempt today where the roof closed but the boot remained in full open position until I cycled the button a few times.
the only oddity I noticed is that the tech must have overfilled the fluid into the pump, it is sitting about an 1/8” above the top arrow.
could that be causing these oddities or would it be unrelated?
