Thanks for the kind words. It is smart to be proactive on the cylinders if you plan to hang on to the car, so that the preventative maintenance is done on your terms, as opposed to an emergency repair.

Any modern convertible top will fail at some point unless the car gets wrecked prematurely. The failure is predictable, depending on age, use and climate. It is completely preventable with preventative maintenance, at age 10-15 years, which entails replacing the five cylinders and the pump. See tophydraulics.com/40-r171-slk-class-04-11

Filling the pump with fluid is covered here: kzfaq.info/get/bejne/opyKjcVju6muY3U.html

@@TopHydraulics Excellent!! THank you very much!! 👍

Correct, it’s the same thing more or less in reverse. Don’t forget to lower the windows first.

We don't have a video on manually opening the top - the process is easier than manual closing it. Lower the windows, close the trunk divider, open the pressure relief valve on the pump, open the trunk lid as shown in the video on manually closing the top, unlatch the front with a 6-mm Allen wrench, manually retract the top. Please contact us directly about shipping parts to Argentina once you know what you need.

The quarter windows should close with the push of your top button after you have fully locked the top and the switch on the right trunk lid cylinder is giving the signal that the trunk lid is secured. We are going over the three ways to secure the trunk lid starting here in the video: kzfaq.info/get/bejne/psmBoJR0vbSvaJc.html

double tap down and hold on the same button for putting the convertible down. it will lower both side windows and the rear windows

@TopHydraulics i had to install xentry on my laptop some russian helped me out and then i can control my little windows

you can do it without that. for the R171 SLK (at least 2006 and up) its built into the car. You just can't control one at a time.@@plank5370

Thanks for your comment, I agree that the chance of failure exists and that quarters are very tight down by the trunk lid. I'm not sure that I understand the comment correctly, though. I have separated the sensor from the cylinder repeatedly in the car and it didn't break. Of course, one has to be careful and of course, plastic can break easily. However, no new plastic was used in the video - it was all from the car in the video. Klaus

@@TopHydraulics The plastic sensor that you showed being removed from the hydraulic cylinder and the cylinder itself was from that car? I’m not trying to be negative here. I would have never known this switch even existed before watching your video. It at least guided me in the right direction. However I can say that my sensor plastic was way more brittle than this. My car probably lived a different life than the one in this video. I’ve owned it for 17 years. Either way thanks for the video. I was just trying to tell people that the area in the trunk is VERY tight and mistakes can happen easily in such cramped quarters and just to be careful.

@@TopHydraulics One last thing. Can you provide the name and part number of that sensor? I can’t seem to find it anywhere.

​@@fitfogey If your switch was brittle, then it was a good thing this happened while you were working on it, as opposed to having a top malfunction due to a faulty switch at some random point. The part number is printed on the switch: A1718207610.

@@TopHydraulics Thank you.

Reverse the steps, but first roll down the rear windows with the console button (if it does not work, fix that electrical issue and test the roof again). Open the valve in the center console, and the roof locks near the rearview mirror. Put the trunk lid in the described position...and open the roof using most force on the c pillars.
