If the screw that is on top of the pump is lost what are my options? ... Ebay search: Mercedes SLK 230 320 Convertible Top Hydraulic Cylinder. ... just surprised that the last two orings are almost useless.other than, its worth it.

Just bring down the hydraulic level to where it should be. Use a drinking straw, place into reservoir, put your finger over top of straw, lift straw up and out of reservoir and let go into a container. This may take you a few minutes, but it will be worth not having to worry about this anymore. GOOD LUCK FRIEND.

check the gear box fluid levels this is usually the cause of most merc faults on the box

First check that you have oil on the hydraulic pump that it is inside the trunk on the rear right fender the oil should be between the marks. If thats ok check when you put the ignition on if the switch that operates the roof is on, should be off, on means that something is wrong, if blinks 6 times one of the 5 or 7 switchs are not closed, check one by one. check the two that close the trunk at the middle, the cover, the trunk limit switch, the trunk switch

first thing I would try, disconnect the battery to the car for a minute, then reconnect it. that may correct your problem.

This symptom almost always points to a lubrication issue. The SLK hardtop is notorious for needing to belubricated every couple of years. Here is a link with directions andphotos:

you should have a fabric panel behind the front seats.if you can not gain access to the motor from the trunk.

Yes, it is explained in detail in your owners manual. If yours is missing and you need a PDF copy, go here:

another suggestion is that you need to have the code re-entered for the hardtop. I just had mine repaired due to a busted hydrolic hose, and the mechanic had a hard time getting it to work properly and ended up having to re-enter the codes.
