What IS the correct way to check roof pump fluid level?
I have been told that checking the roof hydraulic pump fluid level isn't as straight forward as 'opening the trunk and making sure the level is between the upper and lower level'. Is it? I have a colleague at work that owned an R170 and said that the correct way is to start opening the roof using the switch and stopping it when the trunk is fully open but before the roof starts to move. THEN, open the trunk and check/top up.
Is this correct, or, even necessary? What does the service manual say? Whilst I am on the subject, what is the correct fluid to use.... mine is on the lower level, and that is BEFORE using the method above (which I believe drops the level from upper to lower limits just by opening the trunk).
