Your fix is very simple. There are two hydraulic cylinders (MB p/n: 129.800.16.72) in the top of the frame, above the windshield. These are accessed quite easily by...
1. Lowering the soft top
2. Removing the two plastic cover plates over the locking mechanisms
3. Remove any Phillips screws from the weatherstriping at each end of top cover
4. The top cover is removed by simply sliding it back evenly

At this point, you will have both the cylinders exposed. From here, the replacement is very straightforward and only basic mechanical skills are needed – no special tools. Installation is reverse of the above.

Fluid dripping down both pillars - replace both cylinders. Fluid down one side (as in my case) - replace only one. Same part number for either side. The leakage is from seal failure at the drive piston end of the cylinder.

Total repair and mop up time is a lazy 60 minutes. You may need to top off your hydraulic pump (located in the spare tire well). Use MB Hydraulic Fluid (MB p/n: 001.989.20.03.10).
