Unbelievable the customer service you have given me. Emailing me at 10:30 at night helping me with no charge. I found this video and found the problem. You’re awesome man!!!!!!
Glad you were able to fix the problem - that's what we made the video for!
Hi, thanks for the awesome videos on fault finding and diagnosing faults and manual operation of the soft top
There is one part of the Open operation that you didn’t cover
I’ll run through the sequence for my 2005 CLK55 A209
1. Hit open
2. Windows go down
3. Windscreen lock release
STAGE 1: Cylinders 3 and 4 are activated to raise the compartment cover lid until switch S84/19 registers that the bow has released from the lid and switch S84/13 registers that the lid is no longer in the closed position.
STAGE 2: Cylinder 2 is activated to release the front latch. Switch S84/11 registers that the roof is no longer locked, and S84/18 registers that the roof is still in the catch position.
STAGE 3: Cylinders 5 and 6 are activated to raise the rear glass (bow).
Bow goes up fully upright. I am assuming Switch S84/15 has registered that the bow is now in the fully upright position. How do I test that.
6. That’s it, I can hear relays clicking but cylinders 3 &4 don’t run or raise the compartment lid at all
I’ve checked all of the physical parts and can’t see any broken limits or such
Would appreciate your advice
Thanks, keep up the good work in your tutorials
no idea what we would've done without the breadth of knowledge contributed by this channel! All the respect ❤
Top dog, thank you! I've just realised the fault with my soft top within 5 minutes of watching this.
You definitely know your stuff!
Amazing run through, mine had the lh micro switch fitted the wrong way round, you're walk through shows the direction of the fitted switch. And mine was incorrectly fitted thank you 😊
Thanks for letting us know and congrats on fixing the problem!
I’m not really the most mechanical guy, but I do follow along with TH-cam videos pretty well. So glad I found your channel. I’ll be needing the full kit of cylinders soon, and am actually excited to tackle this with a little help from a friend, and you, Klaus.
Hi all, I'm really stuck and hoping someone can give me some pointers? CLK280 2006. On openong the roof the fornt clamps released and roof opened 1/2 inch then stopped. was close enough for me to use the allen key to secure the roof again (thanks for that tip Klaus).
Current situation is that on trying to open the roof, windows go down, then nothing. If boot separator is open, the separator warning comes up. Clears when separator in place so I presume that is not the issue.
I have checked the fluid level and it's ok.
I have checked the 40A fuse and it's ok.
I sent it to a garage that couldn't find a solution. They provided me with 2 error codes;
B1928 -limit switch interlock of soft top compartment cover remains in switched condition
B1953 - limit switch interlock of soft top lock fails to switch
I've followed Klaus's helpful vidos on manually opening the roof and checking all the microswitches.
All seem to be clicking correctly. I alos took off the first relay on the pump and checked it. All OK. Haven't got to the 2nd relay yet - was fiddly to release so left it for now.
While I had the roof maually open and compartment cover was slightly open, I couldn't resist pressing the roof open/close button. Got very excited when the pump engaged and the roof started to move. Stopped after a second or two but perhaps enough to suggest its not pump failure perhaps? Note that the pressure relief valve was open at that point.
I've tried manually opening the roof fully, closing the relief valve and pressing the close button. Again no movment. Put it all back to where I started and its back ot where I started - windows open, then nothing.
I'm at a loss as to what to try next. I'd be happy to break into the wiring harness that goes to the pump to see what sigals the pump is getting if I knew wich lines to test.
Any help would be greatly appreciated!
Thanks, Mark
Thanks for that awesome video explanation and all the details!
I have a problem with my vehicle for quite a long time already and haven't been able to solve it, but now I know which Microswitch with a high probability is causing my issues. Thank you very much!!!!!!
Thank you for your simple yet thorough information 👌. Our new to us CLK500 all working well now.
Super video, I got a CLK 240 which has sticky microswitches sometimes and resulting error messages. Very clear explanation for self diagnosis and fixing (saving lots of money). Danke schön.
Great video - finally figured out why I kept seeing the partition open error.
Thank you very much for sharing your knowledge. An excellent video , one of the best informative videos on TH-cam.
Thank you so much!!! I have been fiddling around for days trying to figure out my warming to ‘lower boot separator/ski bag compartment’
I tried a folded napkin in that left hand side mechanism (that you pointed out) so that the arm could fully press on it & connect & it worked first pop!
Now that I understand where the problem is coming from I can do something about it if it happens again! Thank you :)
Thank you for that great detailed information for my mercedes convertible soft top. Your video's are great thank you again.
Your awesome**thank you so very much for this information I've been having this problem with my vehicle for quite a while 1999 Mercedes CLK soft top 320 I knew it had something to do with the fuses the relay or the hydraulic system but now with the knowledge of this video I can inspect and diagnose all three to determine which is the major problem I will start and begin first with the fuses then with the relays but as also as you said check the hydraulic system for any low fluid or no fluid at all because my hydraulic system might be empty and they may be a leak as well so I might have to get the whole system replaced but thank you so very much for the knowledge and please continue to make these awesome great video
You saved my roof! Thanks for the sound advice 🙌
Thanks for your feedback and glad to hear that the video helped you with fixing the top! What was wrong and how did you fix it?
I had a broken switch where the plastic on top of the spring was completely damaged. I could not even open the car to get to the switch because of that, however I also saw another one of your videos on how to open the soft top mechanism manually and combined with this video, I was able to get in and replace the switch. Thank you 🙏
WOW! Another GREAT tutorial! Thanks! Klaus is awesome!
Top Hydraulics is the best! Greetings from Houston, Texas.
Very clear and excellent explanation! It helped me solve my simple problem and saved me over $1000 that the shop was going to charge me! Thank you so much! Question please: what is the name of the strut that activates the limit switch located on the driver side of the trunk that indicates trunk partition is closed? Do you have a part number?
The gas strut is part number A2096900059. You can find aftermarket gas struts fairly cheap if you google the part number.
Great video BRILLIANT and very interesting and also very informative thank you very much from Canada 🇨🇦
Klaus, I have purchased your rebuilt cylinders before and I am very satisfied. These videos are the cat's meow!. But I found myself somewhat confused where you identified S84/22 near the forward storage compartment just ahead of the Tonn Cover, then later on identifying it as S84/11. You then stated that the same switch S84/11, is on the front header panel above the steering wheel. Also I am not as familiar w/ Mercedes, so when you performed the latch adjustment it was difficult to determine if you were in the front or rear of the vehicle due to the close up video shot. Thanks for the videos however.
P.
Hey Top Hydraulics - can you help me please, i'm going crazy!!!? My 2004 CLK320......top goes down as usual, then won't close, doesn't even try, just states "visit workshop" - First diagnosed a broken S84/22......so replaced, but still the same error??? I then replaced S84/15 as it seemed to be happy to close the roof again if it didn't open past about three quarters open. Changed the switch, again, no fix! I've checked fuses (but as pump operates, so not likely) and I have switched around the yellow relays - still no change. Just to state have owned the car 1 year and roof has worked well. Fluid level correct in the reservoir, so no leaks. I've even taken the rear to bits to check S84/3.....which is undamaged and appears to work correctly. A recent scan on an Autel professional diagnostic tool saw no errors on the roof control module. I double checked S84/13 by jumping the wires as I could do this whilst trying to operate the hood and again, the switch tests good as no change. Been quoted £500 to diagnose by a company 3 hours drive away......car isn't worth fixing if thats my only option - can we save this lovely old 320CLK.....it only has 75k miles!
Great video BRILLIANT and very interesting and also very informative thank you very much from Sydney Australia
That is one of the best videos I have ever seen. Thank you so much. I have a code B1962 the power closing limit switch fails to switch. Please, can you or anybody else tell me where this switch is located?
Hopefully, we can figure out together which switch your code reader is referring to. What are the exact symptoms?
First of all, thank you so much for your help and your interest. It's a 2005 Mercedes Benz 209 CLK class 1.8l SFI. When I pull the opening switch (CAN controlled) the convertible top doesn't move. After this the scan tool reads the following codes: B1870 the output stage or servomotor of rear lock is defective. B1962 The power closing limit switch fails to switch or has a short to circuit 30. At the trunk lid latch, i measured two micro switches, one goes to rear SAM 10/2 and the second to the convertible roof module N52. Both switches are pulling a voltage of 3.6 V coming from the modules to a ground. When i move the roof manually i cannot open the trunk, so everything works fine. I don't understand why the car doesn't notice this. Now I think I made a mistake and measured on the wrong part, perhaps I misunderstood the fault codes. @@TopHydraulics
12:58 Mercedes WIS states 87mm +/- 0.5mm for the w209 according to document P77.33-21 10-06. Mine came out 86.5mm and seems to work fine. But thank you for your hard work.
Brilliant and clearly a very knowledgeable person.
This is a very professional explanation, thanks for it!
Thank you very much, I can sleep easy now and resolve the issue in the morning now :-)
Excellent information video. Thanks
Great Video! Can you tell me the part number for the Bow Lock Limit Switch I don't think you mentioned it in the video. Thanks!
Thank you for the great video. My 2005 clk320 soft top closes fine, but when I opened it, the soft top went into the storage and the cover near the trunk didn't go down. Can you please tell me which switch to look into? Thank you.
Very Good Video, good explained.
Thanks Klaus excellent video
Hello Klaus, I believe I have a leak in my convertible clk200 from 2004. the top opens and closes well in 23 seconds. the point is that after 5 or 6 openings the oil level drops to a minimum. I think I must have an oil leak. I already looked for the oil leak in the trunk of the car and I didn't see anything. I would like to know if I can open the top only halfway to try to find the leak. Is there any inconvenience in stopping the opening process halfway through?
It i s okay to stop the opening or closing process part way. Hard to find leaks are usually from the main lift cylinders, as the fluid collects under the rear seat or in the rocker panels before it drips to the ground. The main lift cylinders typically leak first from the bottom, through the bottom mounting hole.
@@TopHydraulics thank you very mych for your answer I will check it and let you know. Thanks
Good video, I have a w209 my problem of late is when i’am closing the top the very last closure operation when the rear lid suppose to go down flat and the rear window locks down into position, you can hear the motors working but it won’t do the complete closure. But when I open the roof I have no problem with the rear lid locking back down. Any advice would be appreciated.
Thanks for asking. Please give us a little more detail about the closing sequence:
Does the tonneau cover move forward exactly to the position where it would be able to receive the rear bow (rear section of the soft top)?
Does the rear bow come down? If so, how far?
Has someone recently replaced the top lock cylinder, or has any other work been done to the top system lately?
Very helpful. Quick question, I operated my roof yesterday with no problem. Today, nothing. On operating today, my dashboar says roof in operation, but nothing is moving. Where is the fuse or relay for this?
Thanks for asking. You are probably on the right track, as nothing moving on the top and no warning about the skibag (luggage divider) in the instrument cluster normally indicates a blown fuse. It could be a bad relay, but that is rare.
There are two yellow relays next to the pump, attached to the pump's mounting frame. It would be smart to check the fuse first. The fuse is mounted in a small black enclosure (junction box) behind the driver side rear wheel well, practically in front of the pump. There are two fat wires going from the pump's wiring harness to this junction box. These are the red power wire and the black ground wire. The fuse is a flat 40A fuse going to the red power wire. It is not always easy to see whether the fuse is blown or not, which is why I find it easier to use a multimeter. Set your multimeter to DC Volts, have one probe go to ground (for example, the pump's mounting frame) and have the other probe go to the post that the red power wire is bolted to in this junction box. If there is no voltage on that post, then your fuse is blown. A blown fuse is a sure sign of a bad pump motor. Top Hydraulics rebuilds the pumps (their part numbers are A2098000548 or A2098000648, and the numbers printed on the pump are 2098000030, 2098000130 or 2098000330).
The following link shows the location of the junction & fuse box for the pump's power and ground connection: th-cam.com/video/c6WQQG_s-jQ/w-d-xo.html. It is min 0:26 of our pump removal video. If you pause the video right there, then you see the pump in the middle and a threaded post with power wires on it a little higher up and forward of the pump, just before the carpeted panel covers the right side of the image. The threaded post is one of the two posts in the junction bow I referred to, and the fuse is bolted to it.
Thanks for your reply, came across your response by accident as I am still researching the problem. The thing is, this also happened to me last year. One day, the roof working the next day not, I get dashboard message the roof in operation, all the windows opened but that was it, this is why I think it's either a fuse or the relay again.
I took it to a MB specialist who charged me £198 for apparently tracing and replacing a faulty 'resistor fuse' on the pump? So was assuming they meant a relay. Could you confirm the existence of e resistor fuse?
@@chrisdaviesguitar "Resistor fuse" is not a proper term. The only fuse for the pump is the one I pointed out in my earlier response, and I am copying that portion of my response again:
"The following link shows the location of the junction & fuse box for the pump's power and ground connection: th-cam.com/video/c6WQQG_s-jQ/w-d-xo.html. It is min 0:26 of our pump removal video.

The threaded post is one of the two posts in the junction bow I referred to, and the fuse is bolted to it."
If you had a blown fuse a year ago, then it was bound to blow again, because the root cause lies in your pump's electric motor being bad. The fuse does not blow on a good pump motor.
If you had a bad relay instead, that would likely have been caused by a bad pump motor drawing too much current and damaging the relay. Chances are higher that you had a bad fuse, though.
P.S. The fuse is a MIDI 40A fuse.
This guy is simply brilliant….
Mine starts to open, then the top sets back down and the claws close down while the back is partially open. The top doesn't move past just popping open.
It goes until it seems to get stuck. I hear the pump still trying to pump, until I let off the switch. Then it won't continue again, unless I start to close it then try to open it again. I guess you can say, mine gets stuck when the back window is straight up. The cover behind it is only up about 2 to 3 inches.
Mine starts to lift that section behind the window and stops. So it gets a little further than where you had the window up and the back section was down. Mine is up at the back, but the front of the section behind the window is loose, but doesn't go up.
Good video. Is there a way to maintain these 2 switches from dust because I have the chrome door is stuck down
That’s an unusual question, as these switches are not normally sensitive to dust or exposed to much dust. The best dust protection may be to make the chromed cover functional again, as designed.
Hi, Great Video! I have an issue where when my top on my 2009 CLK550 is closing the rear hard partition will not completely cover the convertible top. It is as if the convertible top will not go all the way down into the rear part of the trunk. It than sound like it is breaking and the rear hatch partition isn't fully closed. Thanks in advance!
There are some plastic arms suspended under the bottom rear of the tonneau cover that push down on the soft top as the cover closes, which in turn makes enough room for the cover to close. Take a close look under the cover as it close to see what might be askew there...
Great video.Thank you! I have question.I have a 2008 Mercedes Benz clk 350 cabriolet. The left rear side window does not roll down. Will that interfere with the convertible top operation? Thank you!
Yes, a malfunctioning window regulator will disable the top. Fortunately, our video on replacing the main lift cylinders already shows you most of the steps needed to get at the rear window regulator.
Thank you so much Klaus and co! Can you help me a little? I am able to open the roof but not close, is this a micro switch issue?
Are these videos still commented on?
I have the same car but I’m getting nothing at all when I press the roof button.
No errors.
No noises
No blownfuses.
How about the button for top operation - does it light up or blink when you pull or push it?
Thanks for the video Klaus!! I was hoping to see my E350 issue. When trying to open, I can hear the hydraulic pump running for a few seconds but nothing happens after that. Any idea on that one?
I figured it out. When I received the pump back from Top Hydraulics I didn't realize that the pressure valve was open a little bit. I tightened it up and the top opened. Thanks for providing such a great service. The dealership wanted to charge me $4k for the repair and you all fixed my pump for about $600!! Now that's a win win!
@@_bear_bull Glad to hear that all is well. So you have an E350 A207 chassis, which is very similar to the CLk A209 chassis. From what I am gathering here, we have rebuilt your convertible top pump Mercedes p/n 2078000048. The major difference between this pump and the CLK pump 2098000548 is that the reservoir is in the horizontal position in the E-Class and vertical in the CLK.
Hi there, loving these videos 👍🏻😎 Is there a similar video for troubleshooting A208 micro switch issues?! I have the issue where roof was working fine then the only thing that happens now is the windows go down and that is it!
The roof switch slowly flashes and the headrest switch doesn’t work at all or light up in anyway. Found a blown 15A blue fuse in the boot fuse box and replaced it but this has made no difference. The only thing was the very first time I tried to operate the roof the case cover latch made a noise as if it was trying to release but couldn’t, could that have blown the motor, relay or a different fuse?! Hoping someone can help, thanks in advance 😖
I am not aware of any comprehensive videos for A208 micro switch troubleshooting. However, here is a very extensive thread on BenzWorld.org's A208 CLK forum that gives you all the information you could ever need: mbworld.org/forums/clk-class-w208/519324-clk-convertible-top-problem-solving-common-electrical-hydraulic-system-failures.html
Thank you for the video. My A207 has the problem of bow not raising after the lid unlocks and go to the catch position. I would have to manually raise the bow and the trunk lid up then I can continue in auto.
During Closing, it is also the bow not being able to raise up and kicks out the sequence.
The weird thing is that the bow is pressurized during the closing but not during the raising/extending. Do you think it would be a bad cylinder or bad valve?
I checked the resistance on the solenoids, all read good resistance.
The soft top and windows of our 1999 clk 320 work intermittently. When the windows don't work, neither does the top. Often times, after a 20 - 30 minute drive, the light on the console panel goes off and everything is operational. We think it is a wiring problem in the console. What is you opinion on our problem. Thank you so much for offering such complete information.
Thanks for asking. You actually have an A208 chassis CLK, which is different from the one shown in this video. The windows won't work if the computer things the top is not fully open or fully closed. If you have a light on in the console while you are driving, then it is more likely that the computer reads the top is not fully latched. Do you get this problem also when driving with the top down? If so, then we can likely isolate the problem fairly quickly.
Verry good inform.
Klaus thank you
My 2007 CLK 550's top has always worked until a few days ago when I picked up the car from a transmission repair shop. They told me that they never touched the convertible top. I am getting the message that the partition must be closed but I cannot move the partition one way or the other... I have actually never moved it in the 5 years that I have owned this car. It just won't budge from the closed position. The only thing to note is that after I try to open the top and I get the message, I then press on the button downward as to close the top and I hear something moving in the back and then it stops. The Hydraulic pump liquid is a little bit over the minimum limit (I checked). Please let me know, what I may check next... Much appreciate.
Thanks for asking. The movement of the partition is not intuitive. The first time I tried to move it, I pushed in the wrong direction. It hinges on top, and the bottom part flips forward. It is normal for the struts on the partition to have loast their charge at this age, regrdless of whether they have been used or not. I would try one more time to open and close the partition, so that you can verify the operation of the micro switch.
Superb, thanks
Amazing videos Mr. Klaus! I've had my 06 W209 for 2 years without issue, but now the top only opens to the position at 8:00, and won't even move when I try to pull/open it manually. Sound like a switch 84/11 problem?
That's very helpful
Hi there , wonder if you can help me, I have a w208 2002, the roof isn’t working properly, the red switch blinks when I drive suggesting the car thinks the roof hasn’t been close properly, at the same time am having another two issues which might be related. The boot won’t open with the remote and the rear window defrosting is not working. I checked all wires that run on the boot area and seemed ok. If I manually open the roof it will close and work with the hydraulics and everything works until I move the car a few meters then all the problems start again, any suggestions? Thank you.
Thank you you save the day
Thanks for the interesting video and I have a question? With my CLK W209 I can't remove the roof, just lower the windows and unlock the locks above the windshield. This happens every time after the winter. Nevite goes could be a problem? He constantly writes errors P 1928 and P1923. Thanks Tom.
Nevite? I’m drawing a blank as to what the spelling checker has butchered here.
Also, do you get any narrative for what codes 1928 and 1923 mean?
You are legendary good sir
great video!!
Unique problem with my bow limit switch. The plastic hook comes off the peg in two positions when lowering. Just pop back on and continue. Is fine when raising. Any recommendations?
Thank you . This helped me a lot .
Curious did you show switch s84/3 in this video? Is this a switch that commonly breaks ? Would this cause a problem of the compartment cover going down to finish the opening sequence? Thanks for taking your time out your day. My top opens and stops at the point where compartment cover has to go down… when closing the top goes up 1/4 of the way and then stops. So my next step I manually pull the rest of the top closed until it gets to the windshield. Right after I go back and press the tops operating switch and it locks the lid close as well as finishes the closing sequence. sorry if I’m not clear. Clk 2004
Hi Klaus
This is so helpful. Are the switches in the trunk just as important. Is there a switch in the rear left side panel, next to the rear passenger seat, as MB info says there is on late 2006 a209.
Many thanks.
Paul
United Kingdom.
Hello Paul, every switch in the top system is important and the top will not function without every switch functioning. I am not sure which switch you are referring to. Are they giving you a part number?
@@TopHydraulics s84/3 roof open & s84/4 pawl rotary tumbler switch.
Thank you so much for your kind attention
Paul.
Thanks good info
Hello, you are very knowledgeable. I have a 2002 CLK320. My soft top was working perfectly fine all of sudden stopped working. Is there a way to get a hold of you? Email or a number? I really need help!
Try info@tophydraulics.com
Hey... I have following problem, maybe you can tell me where to look first?!
Everything worked fine, roof is closed.
Next day: no message at display, windows move, hydraulic starts working... thats it. No movements.
Works in both directions (close and open) even though the top is closed. I would really appreciate your hint.
What about the S84/22 or S84/23 catch position limit switches. Would these keep the Compartment cover lid slightly out instead of engaging the Cylinders to pull the final movement to full close?
Would you mind describing the symptoms in more detail?
My Autel says 225 limit switch soft top bow in catch position NO, whether it's up or down. 224 and 226 shows up or down, but it doesn't activate the catch position either way. It seems to stop here. Should it activate for the next step? And where would that catch position be? The windiw goes up and down, no more.
Well, after turning off the key and the pressure releases, then I push the rear section closed, the soft top bow catch position reads YES. I have to close it manually.
Okay, final edit, I hope. Now it works. I tried the windows reset, then it opened all the way again. Then when closing it, it paused a while, but I kept the button forward, then it started going closed. Untill the back cover was straight up and didn't go down. It was stuck there. I got out and pushed it forward a bit, then got back in the car to push the button forward and it finished closing. So I tried it again, to get it to the stuck point again, to take a picture of where I think the problem is, but it continued all the way closed. LOL
I did decide to take the manual straps off the rear hinges, just to see if that helped. Not sure if it did, but that's when it decided to work. I alsow replaced the right rear hinge, as the plastick center piece broke when trying to manually open it. But I guess everything was just getting all stuck. The first time trying to manually open it was very difficult and became easier as I kept working on it. I guess I need to keep everything well lubed up.
Now that it works, my wife will be happy. Now I have to put all the black stuff back in the sides of the trunk. She was getting upset and wanted to sell the car and buy another convertible that works. LOL
Well, had to get out a few times to move the rear cover forward a little at a time, untill it finished going closed. So maybe it's that switch on the rear left cylinder?
B1926, B1928, B1953, B1933, B1930.
Do these codes help, where am I looking for this limit switch?
Please help! My top goes down like nothing is wrong. But doesnt come up. Nothing happens. Sometimes i can get it closed after first closing it manually one time but next day same issue. Tryed to read fault codes with my scanner but it couldnt read it. Do you have any suggestions on where to look?
When you are experiencing the fault, do you get a blinking light on the soft top switch, or an indication in the dashboard that the top is in operation? Does the motor run?
thanks Klaus, good to know.
Hello, great video on the switches. At 8 minutes, mine is in this position when trying to open. Any suggestions?
Thanks for asking. If I understand your question correctly, then your tonneau cover opens a couple of inches but the rear bow does not lift up during the open cycle. Is that correct?
@@TopHydraulics Yes sir. Exactly as it shows at 8 minutes of your video. Thanks for the assistance.
@@leodano2947 Check out switch 84/11 first, as shown here in the video: th-cam.com/video/ZLIdoiw_KTY/w-d-xo.html
@@TopHydraulics Yes, I remember replacing both sides of these switches a couple years back. It's been a project car and had it working at one time, then let it sit. Trying to resurrect it. I know both of those shocks or maybe one since I keep getting that partition open message. Would it be bad to just zip tie that one switch for now, while I check your suggestion?
@@leodano2947 I believe you are asking me whether it is okay to zip tie the micro switch in the left rear of the trunk, which indicates to the controller that the partition is closed. That's okay as long as you don't have any obstruction in the trunk and you don't forget in the future... ;-)
Hey klaus so i was opening my top and the process stopped at the end where I think you call it the tonneau cover it won’t go back down it stops…. It originally opened up to let the top go in but once the top was went inside the back the cover won’t go back down its just stuck up in the air. You know what can cause this? Do you think it’s because of not enough fluid?
Hello, we communicated back and forth yesterday below. I was able to verify that the microswitch clicks when the rear bow is lowered. If the wires are ok where they flex when the cover moves, and the microswitch clicks when the rear bow is lowered, is there another spot in this area I should be checking?
Hiya . Need help summer coming close boot separator keeps showing. Last week I put my daughter suitcase in the car think that did it..
Hiya, thanks for asking. Very likely, the only problem is that the two gas struts that push the luggage divider against the partition switch have lost their charge and need to be replaced. See th-cam.com/video/ZLIdoiw_KTY/w-d-xo.html. The Mercedes part number is 2096900059. You can get aftermarket replacements quite cheaply.
Great video, many thanks for publishing. My CLK500 when opening top, seems to stick when about halfway open just when the glass is going into the trunk and doesn't want to keep pulling to bring the top all the way down. Its intermittent, but more times it happens than it doesn't. The top is up in the air about halfway, and have to push button so moves forward again a little then pull button back and sometimes that does it it completes the soft top folding into the trunk. Any ideas?
Thanks for asking. Is this happening pretty much exactly when the top is in the highest position? When the top is in the highest position and gets retracted some more, the load on the pump changes. At first, the pump had to work hard to pull the top off the windshield. Then it becomes very easy to pull back the top as it almost falls by itself. In that particular position, a valve inside the pump can be responsible for the problem. However, before spending a bunch of money on a pump exchange, you may want to double check the micro switches shown in this video just to make sure they don't create an illogical readout which tells the controller to stop moving the top.
@@TopHydraulics Yes pretty much exactly when top is in highest position. It will pull it to that position and it just freezez, the pump is still making noise but nothing happens.
Hello Klaus, i just replaced the pump with one of your pumps but its still just opening to when the top is in the highest position. It just doesn't want to go past that position, its almost like its not releasing something to pull it back. Any suggestions??
@@btcruiser31 Sorry to hear that. Is the top twisting a little when this happens? Has anyone worked on the main lift cylinders lately?
@@TopHydraulics I don't notice any twisting? The top goes up just fine, entire cycle no issues. But it stops about halfway and won't go all the way down. Windows go down, back window goes up, tonneau flips up, pulls off windshield just fine and right when window start going into boot and top is almost halfway it just stops. I changed my youtube account pic to an example of where its stopping, its not my car its just an example I found and took a pic of it so you can see where its stopping.
I manually closed my trunk piece to far. How can I get in the trunk to open.
Hey Klaus I was hoping you could help me out because I heard you are the expert and have affordable cylinders. So I’m able to open my clk209 with no problem but when it’s time to close it problem is it won’t move at all .. I have icarsoft and I have a CODE B1951 the state of limit switch in Catch position is unreasonable. You Know what the problem could be?
Most likely, this switch is compromised: th-cam.com/video/ZLIdoiw_KTY/w-d-xo.html
Currently the window lifts and it stops :-(
Brilliant!!!
Hi Klaus. I have an intermitent malfunction in my 2008 clk. When I try to open the top the 4 windows go completely down, I have the message Top in Operation and nothing happens, no sound. I said that in an intermitent malfunction because it happened 1 year ago, it didn't work for a few months and then sarted to work again. I have the common problem of the cables in the back window, does it cause humidity that can originate this problem? Thanks in advance.
I just saw in the comment section that this might be a fuse or relay problem next to the main pump, i’m going to see it is this. Anyway, if the problem persists i’m sending you the pump to repair.
Many thanks for your very wise advises. I’ll give you feedback. Manuel
Could be either the pump motor drawing too much current and blowing the 40A fuse or could be the relays on the pump motor. Check the 40A fuse behind the left rear wheel well first, see th-cam.com/video/08R8E3Sc0oQ/w-d-xo.html&pp=gAQBiAQB If the fuse is blown, then the pump motor is burnt out or the pistons in the pump are frozen, making the motor draw too much current. If the fuse is good, then you might be lucky enough to have a bad relay at the pump. Only one relay fails at a time (and the contacts only fail in activated mode), but there are two identical ones. One relay makes the pump motor turn clockwise when activated, the other one makes it turn counterclockwise. Thus, the cheap test in this case would be to swap the two relays for each other and see if the pump starts turning. Both relays need to be in place for this test, but you swap one for another. Again, the latter will only work if the 40A is not blown.
@@TopHydraulics
Dear Klaus,
I couldn’t find today an electrician so I tried myself to swap the yellow relays (i didn’t measure the fuse but i thought, maybe wrongly and with some risk of damaging that if the fuse was broken i woudn’t damage any electric parts).
When I switched it 1) windows down 2) the tonneau made the movement 3) the back window went up and 4) the tonneau fully opened. No more. And then when I tried to close it obviously didn’t do anything so with an openned tonneu I tried to reach those relays and swap them again, which I managed, 30 celsius, under the sun, fortunately I have very long arms. It was a nightmare. I called Mercedes parts and tomorrow morning i will have 2 new relays. The million dollar question is if with te teo new relays (i know one would be enough, anyway) my top will do the full motion it is supposed to do. I’m praying for that because in Portugal Mercedes told me that the problem was two sensors, 800€ and they wouldn’t give any warranty.
Tomorrow I will tell you good news, I hope.
Many thanks for your time and your experteese
@@manuelpedrosd Excellent, I'm looking forward to your confirmation tomorrow that everything works after you have replaced both relays!
@@TopHydraulics Dear Klaus,
I put the 2 new relays and the roof does it’s magic how it’s supposed to do.
Many thanks for being such an amazing expert and a good samaritan.
You rule (and Top Hydraulics)
:) :) :)
@@manuelpedrosd Congrats on your success!
Fantastic video . Best on u tube
hi klaus
thanks for these great videos.i got though a problem with my CLK200 2005.
When i am trying to open my softtop ,when the window goes down , and the top must start opening (front latch totaly disaganged) it doesnt start the movement.could you give me an idea wich microswitch could it be?thank in advance.
You wrote in a follow-on post that your front lock cylinder is leaking. Is the fluid level in the pump's reservor still above minimum?
Hi Klaus, thanks so much for the great video. I have a 2005 clk 320 and i am getting the "top in operation" message when casually driving with the top closed. It does not depend on the top beinf recently open or not. The top closes and opens without problems. Its just that message that appears when driving with top closed.
Can you give any suggestions? :)
Thanks for asking. Has any work been done on the top recently, such as changing the front lock cylinder or even cycling the top manually?
@@TopHydraulics I just got the car a week ago. The previous owner mentioned that the hydraulic fluid and the pump had been recently replaced. And he also mentioned that something in the front had been replaced, but I can happen to recall what it was, maybe it was the front lock Cylinder. I did not ask him if the "Top in operation" message was already there before this service. I am not aware of the top being manually operated.
Thanks so much!
Hi Klaus, i just wanted to follow up I'm here, still having the same problem. Should the front switches?
Good video. I hooked up my scanner and got codes b1900 and b1903. Top will not go down. Says it is opening but nothing happens. Please help.
Thanks for asking. I do not have the scanner codes memorized - what is the desciption of codes b1900 and b1903?
Does the pump motor run while the display is saying the top is opening? If the pump is not running, then you want to check the 40A fuse behind the rear wheel well where the pump's power supply wires are hooked up.
Rear headrest needed to be reset. Took me awhile to figure it out. Thanks for your help.
@@soberlife1264 Congrats on fixing it! Since the comments on this video are turning into a bit of a DIY repair thread, could you help out fellow CLK owners by describing how you figured out that the problem was the headrest, and what you had to do in order to reset it?
great vid thanks
Any idea what cause close trunk lid when operating w209 top? Trunk opens and closes fine and fuses are good.
I'm not sure what's going on. But how would I know if the rear bow cylinders are bad? They still have tension when trying to raise or lower manually. (I Have to wait until pressure is relieved). But during the convertible process the rear bow window is not moving at all. I replaced part number 207 820 79 10. And still no movement. It stops right before the rear bow is suppose to leave the tonneau cover when letting the top down. First all the windows will roll down, then the tonneau cover slightly lifts and then nothing after that. Any idea besides that 207 820 79 10 part that it could be?
Hi sir, I love the metallic paint color on the CLK..can you share the code and name of the paint?
Black opal i have the 550 in this one
Great info, well presented. I've just had my roof replaced & microswitch 2098201910 looks suspect. The "top in operation" warning is continually coming on with the beep warning going off frequently. Does this sound like the right culprit?
Does the top go through the full opening and closing cycle and does it latch properly?
@@TopHydraulics Yes it does, but the final 10mm movement of the rear windows doesnt occur when putting the roof up. The warning goes off when the roof is up or down. All evidence suggests that it has done everything it should, other than the final window seal at the end of the cycle.
@@daveplumpton729 This would be indicative of the limit switch on the right side not getting the "closed" signal to the controller, i.e. the switch that gets triggered when the storage cover is closed. I don't have the part number at hand - it is printed in tiny font on the switch assembly.
Hi, since yesterday the convertible top of my CLK does not work anymore. I had pushed a laundry basket probably too far in the trunk. Now the flap stands vertically in the air on the trunk. Do you have any idea how I can solve the problem? Because you can hear the click of the electronics, but nothing moves anymore.
Maybe I can help you if you can give a more detailed description. Which part are you referring to by the "flap"? Did the top move at all before it stopped working? If so, then please clarify exactly which portions of the to or the storage cover have moved.
@@TopHydraulics As I drove off, I noticed the cold wind and stopped to close the top. The flap (cover) in the back went up, the top went up and stopped. I was irritated by this and pressed the button for the top again, but nothing happened. Friends then manually pulled the top forward so I could slowly drive home while the flap/cover in the back continued to go up vertically. Today, unfortunately, my husband manually pushed down the top in the back again and tried to push the lid/cover/flap lower with a little force. Now nothing works at all. Also no longer goes to pull the top forward, because the lid prevents that. Now the car is completely open outside. I have then visited a workshop. They could not find the error with a Hella-Gutmann diagnostic device. The technician only said that a cable break could be the cause, but he was not sure. I thought that such a device always shows the exact weak point. The cover that closes everything at the end is stuck at about 45 degrees. The red light on the button for the top is on or blinking constantly. In the front of the display it says the top is lowering even though my husband pushed it in manually. Since reading with the diagnostic device, the rear two windows do not go up. They are down and no longer move. Further, the small upright knob above the longer one for seat height is no longer working. No idea what this knob is for (headrests?). This all happened because after a birthday party a guest wanted to help me carry a heavy basket of dirty dishes into the car, which he pushed too far under the ski bag? Are the limit switches S849 not working due to a collision with something in the trunk that touched the cover compartment? Do I have to go to the repair shop or can I fix the problem myself. Unfortunately, my husband has two left hands (German saying). Thanks for your help in advance and best regards from Germany.
Hello, keep doing such a great work, when i try go open the top it sais top in operation but nothing happens, although when i press the button down i can hear the pump for a few seconds. Do you a possible solution for this one?
Thanks for asking. Start out with swapping the two relays on the pump. If that changes the symptoms, then you know you have one bad relay.
I swapped the two relays but it keeps doing the same things, when i used a multimeter the 40 amp fuse doesn't seem to get any electricity because neither the left or the right pole shows something on the multimeter
@@ioannisrinakis9672 In your original question, you wrote "when i press the button down i can hear the pump for a few seconds". In your second question, you wrote "I swapped the two relays but it keeps doing the same things". If you can hear the pump running, then there is power at the 40A fuse.
Yes you are right, my mistake, the fuse is ok. Although i swaped the relays but i still have the same problem, when i press up the button top in operation is shown and when I press it down i can hear the pump for a few seconds.
same issue for me
Hi there, got a 2003 clk320, I saw in the comments that someone had a similar problem that you replied to but they never got back to you so the problem didn't get resolved here.
Almost 12 months since I last opened the roof, opened fine, tried to close it, nothing! no pump noise, light blinks red on the switch, message, visit workshop, found your vids, got it closed manually.
Tentatively tried to open it again and seems to want to, didn't let it though, getting late. I did notice that where you put the straps through to manually open that compartment, one of the plastic levers on the right hand hinge is broken, (UK spec) does this operate a switch? and could that be the fault? or is to that everything is so tight/seized, because that compartment cover seemed hellish stiff to move.
Anyway great vids, hopefully I'm not to late to the party :)
What are the last six numbers of your VIN?
@@TopHydraulics Thank you very much for the reply, honestly I didn't hold out much hope as the video is some years old now. You Are the MAN!
012106
@@rustynail6363 The VIN confirms that you have the newer style case cover cylinders with the release buttons on the bottom, so that eliminates the concern that you might have an early production version with the obsolete case cover cylinders that seize.
The plastic lever in the hinge does not operate any switch. It is very hard to move the compartment cover manually in the first place. When the cover moves unevenly, maybe caused by a plastic piece getting stuck on one side, that increases the chances that the micro switches get damaged which indicate ‘compartment cover in catch position’ and ‘compartment cover closed’. They would be my first suspects - check them out!
@@TopHydraulics Thanks for that will look into them.
Kind regards
Rusty
Thank you Klaus! My A2098201910 Limit Switch, Left, keeps breaking, (casing cracks). Any idea why? The Limit Switch is properly seated and the torx screw is tight.
It would appear that your case cover is not moving evenly. The most common reason is air in the system from a leaking actuator, or it could be something binding in the case cover's linkage (check the hinges), or it could be one of the case cover lift cylinders having a lot more internal friction than the other one. Check the fluid level in the pump first, then check the linkage and hinges, then observe whether the case cover comes down a little tilted to one side.
The "top in operation" warning is on but everything looks closed, they only thing I noticed is the front windows are not fully up.
Can you share more details, so that we can help you better? For example, did the problem start while you were opening the top, or did it start while you were closing the top, what work has been done to the system lately, can you hear the pump running in the trunk when you pull or push the button?
@@TopHydraulics the pump comes on and the top opens and closes the front two windows don’t go the extra inch at the end and the dash say “top in operation”. This all started after it snowed. There has been no work done on the top.
Is there a good website to get the s8522 switch from that you can recommend
@@bookertsmithjr That should be part number A2098201910. Best google who has it available and pick your best option.
El mío cambie el cilindro principal el que tiene 3 latiguillos y ahora no abre,si le obligó o ayudó abre y luego cierra perfectamente que puede ser?
What’s the part number for struts in the compartment cover. Do you have a link where I can purchase it?
The part number for the gas struts is printed on the struts. It is 2096900059. We don't sell them, but there are plenty of aftermarket suppliers if you don't want to buy directly from Mercedes. Simply google the part number.
hi there i have a clk 200 kompressor the top opens and closes great but it says top in opperation on the dash, also the side windows wont go into there final possition i.e full locked car, do you have any idea what could cause this.
Most likely, the "compartment cover closed" micro switch on the right side of the storage compartment is not giving the signal that the cover is closed all the way, see th-cam.com/video/ZLIdoiw_KTY/w-d-xo.html This could be because the switch is broken, or it could be because something is in the way of it getting triggered. Check it out while the cover is open...

Habe auch problem mit hinteren rechten scheibe, und zwar wird die um einege cm geöfnet und stopt, ist wieleicht dass die ursache. Danke.
Can the cylinders for the rear bow leak from the inside and I not be able to see it physically coming out?
I believe you are referring to an internal bypass or "blowby" inside the rear bow tension cylinder A2098000972. While this is possible, it is very rare.
Hi, question. My rear right quarter window stay stuck up position, and my convertible starts to open when operated but stops pretty much straight away. Is the problem with my roof linked to the rear window not operating? Thanks in advance
Indeed, the window regulator needs to be fixed or replaced before the top can operate properly.
Thanks for Your videos. I ve got the problem - when I try to close the top, it moves normally, but when it hit the front, it stops. When I strong push the roof manually and move right, left it continue to work. What can be the reason ??
Start by checking switch S84/18 "limit switch in catch position", see th-cam.com/video/ZLIdoiw_KTY/w-d-xo.html
@@TopHydraulics I ve just regulate the middle lock mechanizm as You suggest in the video. Now the top closed properly hovewer now in the next step the rear flap dont want to close.
But it works, because when I want to open the top, it normally closes.
I can't close it when the top is on.
@@TopHydraulics many thanks, i’ll do tomorrow the test and i will let you know. Hopefully i messaged you and found someone that really knows a lot about the subject :)😊
