If the hydraulic fluid level line is about 1/2 inch above the full arrow marking on the tank could that cause damage to the system? I am a first time user to this forum so I hope I doing right with asking this question. Thanks. Lou

Vario hydraulic as in roof system? Regardless of car brand, a high level here won't cause an issue other than possible overflow out the vent.

Yes as in roof system. Thank you for your answer about the oil level.
