SOURCE: slk 230

The hydraulic cylinder lines are designed to not be removable from the cylinder. There have been people who have done it, me, but it requires redesigning the attachment point. Not for the novice. If you are replacing the part, the new one comes with the lines attached. You must remove the plastic interior in the trunk and disconnect the lines at the pump. If you are only rebuilding the cylinder and reinstalling it, it can be done without removing the lines from the car. You will rebuild it sitting in the passenger seat. you will need the replacement O-rings sold on Ebay.

Bad news, if you are experiencing one cylinder leaking, it is very likely the other two that raise the top will begin leaking very soon. This is because all three cylinders use a rod seal made of the same material that degrades over time. The two remaining cylinders (of five) that raise the trunk almost never go bad because they were originally designed with the O-rings.

Costs:

-New cylinders run $300 to $400 apiece
-About $40 to $60 to have your cylinders rebuilt, apiece
-Around $10 to $20 to buy the O-rings on Ebay

SOURCE: 1998 SLK 230 Hydraulic system worked

The problem may be with the closing assist pump or the sensor on the trunk. Try first to remove the fuse of the pump in the fuse box at the trunk. It is usually the #9 fuse in most models. Check if the fuse is bad if not leave it out of the socket for a minute then put it back in to reset the system. See if it works.

To get the line removed use the fork of a 7mm wrench to get the hose out of the pump. The trunk line is labeled 'HD'. Make sure to pry it out in the direction of the hose in order for you not to break the nozzle.

Other details of the issue you may use the link below as reference.

It is for another model but it uses the same parts.

SOURCE: where is the fill plug for 1999 mecedes slk 230 hydraulic roof pump

Should be a screw on top of the pump - upper right side.
It should fit a hex/allen/key size 5.
Oil level should be between min and max.
After filling, tighten screw with 8NM torque

If you look down through the "brush", you'll see the screw.


The screw on top of the pump is for the refill, the one on the side is to releave the preasure when you open the top manualy. There is a refill line on the side as well.

1998 Mercedes Convertible Top Slow and Drips Oil


Your top is moved by an electric motor wich operates a hydraulic pump which moves two pistons which move the top.
The "oil" thet you see is probably hydraulic fluid leaking from the drain hole in the car near the tire.
You have a leak in the hydraulic system.
You need to start at the motor/pump/reservoir unit behind the seat and find the leak.
Most commonly, it is a bad line. Second in popularity is a bad cylinder(s). Third on the list is the motor/pump/reservoir.
If you replace a line, do them all. If you replace a cylinder, replace them both.

This symptom almost always points to a mechanical issue, not an electrical one. The SLK hardtop is notorious for needing to be lubricated every couple of years. Here is a link with directions and photos:

Sticking joints are the most common culprit to intermittent raising and lowering problems. Once those have been lubricated and that has been checked off the list, then consider looking into electrical issues.

The moisture from the rain may be helping to lubricate these joints and that might be why it works fine in the rain...

1999 slk Mercedes Hydralic leak


The pumps rarely need replacing.

SLK top leaks are almost always caused by one (or more) of three hydraulic cylinders in a system of five cylinders. These three are the small latch cylinder located under the headliner, and the two larger cylinders that raise and lower the top located just behind both seats. The rod seals in all three are made using a proprietary material that is designed to break down over time. The other two cylinders in the system that raise and lower the trunk almost never go bad. This is because they are designed using the time tested Nitrile rubber O-rings, not the Novathan material that are in the other three.

Also, the SLK hardtop mechanical pivot points are notorious for needing to be greased every couple of years. When they stick, it seams as the pump does not have enough power to raise the top. Some times the pump gets blamed for symptoms that pertain to other problems.
