The system is self bleeding as long as there is enough fluid in the pump. The reason is, each hose on the cylinders serves either as supply line when moving the cylinder in one direction and then as return line when moving the cylinder in the other direction, or vice versa.
Hi, I thought I was almost an expert with the Vario roof having owned a R170 for 8 years I have rebuilt all 5 hydraulic rams, replaced the pump and diagnosed a broken wire in the wiring loom to the microswitches that was causing the quarter windows not to operate. It is used regularly and has been working perfectly for a couple of years and now I have a new issue which lead me to your video. I have no power to the pump motor, the relay is good but no power to the pump not even at the 40 amp fuse. There is power to the boot lamp fuse but none heated rear window fuse either. I have checked all the fuses in the engine compartment. All I get is door and quarter window going down when button pushed back and go up when button pushed forwards. Button turns red when operated but none of the flashing or annoying beeping that I have experienced with previous problem. Can you please advise what the try next.
If there is no power to the 40A fuse for the pump, then that is what you want to investigate. Ultimately, that power comes directly from the battery without any switches or modules in-between.
Hi, I performed the test listed and the pump pulled 30A when deadheading as shown in the video, and only about 20A when attempting to unlatch the front cylinder. As the front cylinder was dripping slightly anyways and attempting to unlatch but lacking the pressure to do so I went ahead and purchased the front cylinder from top hydraulics. With the new cylinder my problem persists and the pump still only pulls 20A but will pull 30A when jumpered and deadheaded. Would you recommend purchasing the entire pump at this point?
Thank you for this very informative video, there is an oil leaking in the rear passenger side. The leak is near the front of the rear tire, Do you have any idea for this issue?
That would most likely be a leak from the passenger side main lift cylinder A1708000672. Here is the video on replacing it: th-cam.com/video/9A2d4A3PyyE/w-d-xo.html You may also want to watch this introduction: th-cam.com/video/KwoKQhN4vhw/w-d-xo.html

Wow, that second sound where it's not working fully is exactly what mine sounds like! And I already had the front cylinder replaced when it failed. Is there any harm to leaving it? It's slow but it's not terrible. Actually, how fast is the R170 top supposed to take? I timed mine at 60 seconds.
Your top is moving at about half the original speed now. I don't have the number memorized for how long it normally takes an R170 top, probably around 30 seconds. The fastest late model hard tops take about 18 seconds, the R230 SL top takes 22-30 seconds and my old Mercedes R129 SL takes 35 seconds. There is not normally any direct harm with procrastinating on the pump replacement, except that you create more sludge in the fluid from extended pump operation (not a big deal since the pump is going out, anyway) and that in some rare cases the electric motor can overheat if it is running too long. I doubt that you are currently causing harm, but it will get worse and you might be stuck having to finish the opening or closing cycle manually at some point. The pump failure is inevitable and you may want to plan ahead for the best time to tackle the pump replacement.
Most likely, switches S69/7 or S69/8 are not indicating to the computer that the trunk lid is fully latched in the forward position. See th-cam.com/video/uXKSfLEPWgE/w-d-xo.html Try lubricating the latches first or see whether the weatherstripping on the trunk's rim is too tight.
Help!!! I purchased a 2004 SLK, was not told about the roof lock leaking... ran down the fluid until the last time it closed it took forever and the red button got HOT. I performed the cylinder rebuild as seen in other videos and now when I retract the top, it does unlock, but that's all. The trunk never opens and the pump just keeps going until i let go of the button. No flashing light on button or anything else. Any ideas? Pump? Switches? I was wondering if air in the system, although I'm reading about self bleeding... I don't understand why it's not working anymore

Mini R52 pumps are used in Mini R52's only. They do have internal valves that fail, or the piston assembly can wear out.

Hello Lloyd, thanks for asking. We sell only hydraulics - no weather seals. There are several options on how to tackle fixing your R170 SLK Vario roof hydraulic system. Pricing for all options is on our website's SLK section: www.tophydraulics.com/20-r170-slk Rebuilding a single cylinder that you send in first can be as low as $55 plus shipping, with standard return shipping within the US starting at $10. The most popular option is to replace and upgrade all five cylinders and the pump together, shipping from Top Hydraulics' inventory first and you subsequently ship back your cores (the original cylinders and pump) to recover the deposit. This would currently be US$805 plus $600 deposit plus shipping. Standard shipping within the US for the full set with pump is currently $20, International shipping via FedEx International Priority (which is extremely fast) for the full set of cylinders and pump together is currently $90.

Klaus, can you tell me how I can build an ammeter similar to what you are using in this video? I would like to test my hydraulic pump on my R170 before I send it out to Top Hydraulics. Thanks.
We happened to have this meter in the shop and it was easy to film that way. If you need to buy an ammeter, then you may want to go with an inductive one that does not need any wiring - simply put it over one of the leads going to the motor (not both, or they will cancel each other out).

Good to know 😊
Why does the system NOT require bleeding after installation of any new hardware?
The system is self bleeding as long as there is enough fluid in the pump. The reason is, each hose on the cylinders serves either as supply line when moving the cylinder in one direction and then as return line when moving the cylinder in the other direction, or vice versa.
