SL500 soft top problem
1997 SL500
Driver's side Every time I disengage the soft top, there is a squirting (liquid) noise at the connection point at the top of the windshield, and then an oily substance drips on the seat, or me. Photo attached - there's a drip forming... Any thoughts on what might be wrong?

Common problem. They all need to be replaced. Replace both of them at the same time.

If you decide to DIY this problem, this is a very good 'How-To'
http://www.peachparts.com/Wikka/R129TopRelease Both of the front hydraulic cylinders will have to be repaired or replaced even if only 1 is leaking presently, the other won't be far behind. One of the most economic solutions is to have them rebuilt. Mercedes Hydraulic Cylinder Rebuilder Dennis Ficken 16285 S. Chester Olathe, Ks 66062 (913) 544-4521 mercedescylinders@sbcglobal.net

Having said that, I have another problem. After deploying the soft top, I can hear the sound of what seems like intermittent sound of a pump activating every five seconds or so. If the soft top is retracted, the sound goes away. I found the device that is making the noise in trunk above the battery. Is it supposed to make that noise and keep "pumping?" Is this the main hydraulic pump? Does this condition indicate low fluid level perhaps?

On second thoughts, it turned out that the hydraulic pump was not the culprit but the noise comes from what ever is behind the insulation in the picture attached.

Vacuum Pump...look for loose or cracked line(s).
The hydraulic pump for the top is in the bottom of the trunk, under the spare. Since you had a leak, you may need to add the proper hydraulic fluid to the level line. Bob
