Bonjour Bonjour J'ai un souci avec mon toit ouvrant de Mercedes SLK quand j'appuie sur interrupteur pour ouvrir mon toit ça clignote mais le toit ne marche pas si j'appuie deux fois les vitres se baisse j'appuie pour le refaire mais j'attends le moteur de la pompe hydraulique oui des fois c'est le contraire quel est replié dans le coffre je peux plus le refermer et le lendemain des fois ça marche
Here is how your message translates into English: "Hello Hello I have a problem with my sunroof Mercedes SLK when I press switch to open my roof it blinks but the roof does not work if I press twice the windows down I press to redo it but I wait for the engine of the hydraulic pump yes sometimes it is the opposite which is folded in the trunk I can no longer close it and the next day it works" If I understand you correctly, then sometimes the pump motor will run, and sometimes it will not. This can happen with the top up or with the top down. If the switch blinks, which it does for you, then you have an electrical problem. My first guess is the luggage divider in the trunk. Have you checked to make sure the micro switch on the right side of the luggage divider is working properly?

I performed this test and no fluid leaks out of #33. I am getting 25 amps off the pump but the lid does not open at all. I push the button back and the pump's pitch goes from lower to higher. If I push the button forward, the pump sounds has a lower pitch. I would appreciate any help on this very much. Thank you.
If the pitch goes from lower to higher while the pump is running, then you have an internal bypass in the pump. (Unless you are low on fluid, of course) What fluid has been used?
@@TopHydraulics Thank you for your reply. The sound pitch fluctuates only when the button is pushed back. When the button is pushed forward, I hear the lower pitch sound on the pump and can see the lid tighten. The fluid is thin with a yellowish tint. It looks like brake fluid. Also I noticed that one of the quarter windows is stuck in the down position and the red button does not light up at all.
@@benchiburashka3778 Brake fluid would explain the symptoms. It would have ruined the solenoids in the pump. Also, brake fluid will make all cylinders leak. Brake fluid is not compatible with the seals in the system, not even with our superior seals. Break fluid is clear, Mercedes fluid 0009899103 is yellowish. Disconnect one of the hoses for the front lock cylinder, collect a few drops of fluid and see if it mixes with oil. Brake fluid beads off of oil.
@@TopHydraulics Thank you. It is yellowish but will do the test. I will also refill it again with Mercedes fluid. Can the solenoids be replaced or need a new pump?
Thanks for asking. On an R171 chassis SLK, this would be hose # 10 for top lock cylinder A171 800 00 72. The R171 pump A171 800 01 48 or 1708000030 is mounted in the center behind the seats. Note that the R171 pump motor turns in two different directions, depending on what it is supposed to move. That's why it has two relays. One relay gets activated to make the motor turn clockwise, the other one gets activated to make the motor turn counterclockwise. If you want to make the motor turn, bridge pins 30 and 87 in the connector that one of the relays goes into and experiment with which motor rotation you actually need.

is hose #33 the same for the R171, in other words can I do the same test on a 2007 slk 280?
