Hi All Although I no longer have my Copen (it is now in France), I wonder if anyone and especially ‘threepot’ with his incredible knowledge of the Copen roof mechanism, could tell me how to add/top up the Hydraulic fluid on the Copen roof system and also exactly what Hydraulic fluid should be used and how to check for the correct level. I did find an old post from ‘Adam K’ about the Hydraulic fluid but I feel this is a subject that really needs clarification. Finally, would anyone agree that this could be the reason for the Hydraulic motor to sound much louder and for the roof/boot mechanism to operate much slower to the point where you have to help it move/open/close at certain parts of the operation? Many thanks in advance and best regards KS
