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!!!!!!

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!!!!!!

no idea what we would've done without the breadth of knowledge contributed by this channel! All the respect ❤

Thank you for your simple yet thorough information 👌. Our new to us CLK500 all working well now.

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!

Thank you very much for sharing your knowledge. An excellent video , one of the best informative videos on KZfaq.

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.

Thank you for that great detailed information for my mercedes convertible soft top. Your video's are great thank you again.

Top Hydraulics is the best! Greetings from Houston, Texas.

This is a very professional explanation, thanks for it!

I’m not really the most mechanical guy, but I do follow along with KZfaq 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.

Brilliant and clearly a very knowledgeable person.

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 :)

Great video BRILLIANT and very interesting and also very informative thank you very much from Sydney Australia

Great video BRILLIANT and very interesting and also very informative thank you very much from Canada 🇨🇦

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

Great video - finally figured out why I kept seeing the partition open error.

Thanks Klaus excellent video

Very Good Video, good explained.

You saved my roof! Thanks for the sound advice 🙌

Thank you very much, I can sleep easy now and resolve the issue in the morning now :-)

Excellent information video. Thanks

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 😊

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.

great video!!

WOW! Another GREAT tutorial! Thanks! Klaus is awesome!

Fantastic video . Best on u tube

Superb, thanks

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!

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

Klaus thank you

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?

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?

This guy is simply brilliant….

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?

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.

Thank you you save the day

Verry good inform.

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?

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!

Any idea what cause close trunk lid when operating w209 top? Trunk opens and closes fine and fuses are good.

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

You are legendary good sir

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?

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.

Thanks good info

great vid 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.

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.

Brilliant!!!

Hallo Klaus, Ich habe ein zwischenproblem der nicht in der video ehrwähnt wurde und zwar; Hate den hinteren linken mikroschalter gewächselt da der gebrochen war und jetzt, wenn die hintere scheibe wieder auf geht, pumpe läuft, aber hebt die verdeckklappe nicht. Habe bemmerkt das in den selben moment wen die hintere scheibe auf geht, wird die forderseite aus und wieder eingeglemmt. Habe auch problem mit hinteren rechten scheibe, und zwar wird die um einege cm geöfnet und stopt, ist wieleicht dass die ursache. Danke.

Does anyone know which one is the power closing limit switch?

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.

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.

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.

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.

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?

Thank you . This helped me a lot .

Klaus, do you know the part number for the bow limit switch S8415 by chance? Since I'm replacing all the cylinders with your new parts I'm going to replace that switch also and 2098201810 while I'm at 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?

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

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?

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!

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?

Hello, i have a clk320 2005 and the pump is stuck like in the video but when opening any suggestion?

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?

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.

What’s the part number for struts in the compartment cover. Do you have a link where I can purchase it?

I manually closed my trunk piece to far. How can I get in the trunk to open.

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!

Good video. Is there a way to maintain these 2 switches from dust because I have the chrome door is stuck down

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.

Hiya . Need help summer coming close boot separator keeps showing. Last week I put my daughter suitcase in the car think that did it..

Can a limit switch still be broken even if it clicks? Like a malfunction with the switch itself?

Can the cylinders for the rear bow leak from the inside and I not be able to see it physically coming out?

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?

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.

Hello. What would cause the rear glass not to move? When I try to open my top the back lid comes to a tilt right before the rear glass is suppose to lift. But the rear glass isnt moving. When I manually do it, I can tell the struts still has some tension but wondering if that could still be the problem. Or is there a switch somewhere?

Hi sir, I love the metallic paint color on the CLK..can you share the code and name of the paint?

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?

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.

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 😖

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 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 ??

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?

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? :)

Hi do you know the correct part number for the "Bow locking limit switch" cover? as the part number for the switch is not mentioned in the video? the metal faceplates on mine on the passenger side have sheared off. The switch itself is fine , but the metal part needs replacement. Because its not there, the bow rollers dont make contact with the switch. Also, do you know if the metal part on the drivers side is the same? if so i can swap them round at no cost. I understand they both have two different numbers , but they are both printed on them ? Mercedes quoted me £150 but they say the original part was superseded with a replacement part number. if they are the same , ebay is the way

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.

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.

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?

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?

hello klaus, I have the 04 clk 500 I changed the s84/20 (left and right) checked the continuity on both switches, with meter, and changed the soft top control Module in your video at 3:41 is my problem the lid compartment wont wait for the rear glass to fall in place to lock when I am closing the top, what should I go after next? when its closed I hit and hold actuation switch windows drop it says top in operating but nothing is happening, please help with your superior education on this issue. bless

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.

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?

Hi Dear, I am facing a problem with my Mercedes 230 CLK , When I am driving if the car goes in the road bump shutters are opening automatically. Long time onwards back seat headrests are up positioned permanently. Please guide me how to solve this issue.

Currently the window lifts and it stops :-(

thanks Klaus, good to know.

The limit-switch at 9m 24s, does anyone know the Mercedes part number for it? I have the A208 soft top..

I made the mistake of closing the storage cover all the way before stopping and lowering the rear window in place. how do i open the storage cover with the rear window still up? it seems locked in place. thank you for the help
