It's hard to tell from the photo what the unit is meant to be, but what I'd suggest is cleaning it all over and looking for a part number.
Since its a Mercedes machine I'd guess that it's made by Bosch. Then either search on Google or contact your local truck factor/Bosch agent with the part number who will tell you if there's a repair kit available.
It sounds like the same kind of problem that the air assist chamber on U900/U1100s get.
Cheers,
