Mercedes A209 CLK - How To Troubleshoot the Microswitches

[@BradsAdventures]

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!!!!!!

[@TopHydraulics]

Glad you were able to fix the problem - that's what we made the video for!

[@terryflynn2825]

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

[@TheCarusoGroup]

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

[@markbatt-rawden1318]

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

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!

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

[@TopHydraulics]

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 kzbin.info/www/bejne/Zmm1aXhpiMhjpbM&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.

[@manuelpedrosd]

@@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

[@TopHydraulics]

[@pedroferreira2781]

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?

[@TopHydraulics]

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]

Hopefully, we can figure out together which switch your code reader is referring to. What are the exact symptoms?

[@juttaschierge3659]

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

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.

[@fadiabdo9976]

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

[@TopHydraulics]

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.

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.

[@KimMichaelTasker]

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?

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

I would really appreciate your hint.

[@cookie135]

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.

[@TopHydraulics]

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?

[@weegirdy]

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.

[@TopHydraulics]

How about the button for top operation - does it light up or blink when you pull or push it?

[@malakwinnson428]

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?

[@shark70007000]

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?

[@KO-yh5pl]

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

[@after6tuning]

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.

[@shark70007000]

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.

[@xstichat]

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.

[@TopHydraulics]

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?

[@chrisdaviesguitar]

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?

[@TopHydraulics]

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: kzbin.info/www/bejne/mWe6goR9lNhgoLM. 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.

[@chrisdaviesguitar]

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?

[@TopHydraulics]

@@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: kzbin.info/www/bejne/mWe6goR9lNhgoLM. 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." 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.

[@TopHydraulics]

P.S. The fuse is a MIDI 40A fuse.

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!

[@TopHydraulics]

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...

[@ATMRecords704]

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

[@kojakman2]

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.

[@malakwinnson428]

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

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.

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.

[@TopHydraulics]

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.

[@newpart6625]

@@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.

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.

[@TopHydraulics]

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 kzbin.info/www/bejne/kH2slaKfrMR-irs 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...

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?

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.

[@TopHydraulics]

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.

[@raphaelserfaty2179]

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.

[@TopHydraulics]

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.

Obviously, you have a leak somewhere. If you don't find any fluid on the trunk floor, then the most likely source of the leak is one or both main lift cylinders.

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.

Are you referring to the gas struts that keep the trunk divider closed?

The Drivers side (uk rhd) is for decoration and to hold the roller. I have taken mine out hoping to be able to swap either side round , but unfortunately this is not possible as although the mounting plates are the same , the spring loaded doors (oval part) are mounted in opposite polarity. I have no idea why they designed them this way . The part numbers are A2097500625 which is for the UK passenger side, which contains the switch, and ending 525 for the uk drivers side which does not contain a switch. I guess for a left hand drive vehicle the opposite may apply, but I cant say. Both part numbers are printed on the part, and a blue dot is highlighted to indicate which part it isn't... just to confuse things further. I have been told my several ebay sellers as soon as they list the side that contains the switch they are immediately sold as this is a very common problem on uk cars.

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 kzbin.info/www/bejne/kH2slaKfrMR-irs

@@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.
