Hi guys have you checked the health of your batteries? Mercedes cars are very sensitive in that respect and a low battery can cause every kind of problems soft top ones included. More, try to operate the top with the engine running just to be on the safe side. If this still doesn't work try to reset any error codes the car might throw at you. How? Different car years have different methods of resetting error codes that's why we always suggest to fill profiles with the car year and your location: to help us help you in the quickest and best way.

Good luck for now and please report your findings.

Cheers.

You can order it online. Depending on where you live, picking one up from the Dealer may be cheaper as you don't have to pay postage. Have you check your tool kit ? it should come with the car.

Please help yourself by reading the forth Blue Sticky located on the Home page of the R129 Forum. Then go to the bottom of the Sticky and you will find two Threads. One addresses the RST 'hydraulic system' and the other addresses the RST 'control module'. It's my guess that since you have a 1992 500SL you will be replacing ALL (11-12) hydraulic cylinders seals soon. It would be a good idea to become well educated on the RST system.

Please read http://www.benzworld.org/forums/r129-sl-class/1184702-soft-top-manual-lift-tool.html#post2419052

"It's Spring Time and the SL owners are wanting to use there RST."
