R230 top hydraulic pump reservoir location.. fill opening..?
my front lock cylinder is leaking..
to replace it i have to get the front part of the top up far enough to R&R it..
to do that i need to add oil to the pump..
does anyone know where to fill the top hydraulic pump reservoir.. ?
i can see the pump and reservoir but see nothing other than what looks to be a small allen head steel plug in the steel block of the pump assembly..

MB uses an injection tool, in one of the allen ports. I burned a small hole in the plastic container and used a conventional injector with a tube to suck out and renew the hydraulic fluid. Don’t drill, as debris might contaminate the delicate system.

That pump looks way different than the one in my 2005 SL, it looks like the one in my 2009 SL, i dont see a port to fill it. Might have to melt a hole in your reservoir and fill it through there, it's not pressurized or anything so it'll be fine. You can just duct tape it back after you fill it.

I found a plug on the read of the reservoir. The allen wrench which fits the plug on top of the pump, fits the reservoir plug. I used a bottle long nose to fill the reservoir. The reservoir is not pressurized. I filled the reservoir to the marks on the side of the reservoir. My trunk opened, the hard top came back up. I will have to top off the reservoir again but, the hydraulic pump works again and no need to go to the dealer. Oh, currently the dealer and second party repair shops are backed up…two weeks.
