Mercedes Soft Close Trunk / Boot Fuse Reset + Secret Tip!
HTML-код
- Опубликовано: 13 сен 2024
- Here I show you the infamous 20A fuse that you need to pull for 15 secs to reset the trunk or boot pneumatic actuator. This is typically required if you have trouble getting your trunk to soft close due to air leaking from the pneumatic actuator which can develop cracks and leaks.
I have made a separate video here on how to determine and fix a leaking actuator:

5 minute success fix on the other side of the globe...Thank You!
Excellent! thanks if you chose to follow me
You couldn't make a better vidéo ! VERY PERFECT AND HELPFUL!!! Thank you so much. Every one else talk about the pump and accessories but never say to check the fuse first. You are the best, really !!!
Such kind words! Thanks so much, give us a thumb !
Great fuse removal tip, it always drove me nuts trying to remove the fuse even with a fuse puller tool. *****
You're welcome! thanks for considering subscribing to me !
You are the employee of the year, thank you for your help
Glad you got it working, I did another video on how to permanently fix the actuator with epoxy
Amazing tip that allowed me to have the roof down whilst mid two week road trip! You saved us!!!
Lovely, you may need to keep an eye on your actuator, I've done another video on how you can fix it, it's easy to get to and they usually get small cracks. Appreciated if you decide to give a super thanks 🙏
Great video. Didn't want to go try other 15 minutes videos.
Thank you so much!
nothing worse than bloated videos !
excellent quick and short tip. Much appreciated.
Thank you for this video, it was a great help and it solved my issue instantly. Cheers 👍
Glad it helped, did you get it fixed
@@GrooveOn Well I thought it was, but then after a few closes it stopped working again. I pulled the fuse out, out it in again. It worked a few times but then stopped. Any ideas what I should do next, maybe take it to the mechanic? Thanks.
Thanks, was getting boot not closed warning light and fuse reset have solved it (at least until I built up the courage to epoxy the actuator!
Superb! Solved my problem instantly. Good tip on the fuse.
This has worked perfectly for me. Thank you!
So nice to hear it when I have helped! Thanks for the 👍
Thank you dear for your good information, it’s fixed in just one minute 🙏🙏🙏🙏🙏
Fantastic you're welcome
Greetings from Florida!
thanks for the video. I'm having an issue where my cls 63 amg trunks been opening randomly, it can happen every 3 hours or every 2 days.
I hope it can be related to the fuse, as recently, my hood warning been coming on saying that the latch is open when its not, and i hear they share the same fuse.
a really helpfull video!! Thanks!
My idea for a next movie is how to check a leak from the hoses ? By the way, good video 👍
Thanks for the kind words!
brilliant !!!! thank you so much
Glad it helped you! If you find time to subscribe it all helps my little channel! Thanks
Many thanks its really handy..... well soft close door system for doors, can we disable it?
This is a great video - and I feel like it’s the exact same brakes as a 2003 SL500 r230 - also, did you grease the pins before putting them in?
The pins were easy to remove on brakes, so I just left them with no additional grease
Excellent !
Great video! Worked for me! How long until I have to replace the actuator? Or is this all I need to do?
I recall doing this for about 6 months then the old actuator gave up. You should check out the other video I did which shows all the areas that leak to help you.

Or you can buy another used one. Good luck!
Fantastic, Thanks so much!
Welcome mate
Great Tip and video Al ;-)
Thanks very much, give me a thumbs up👍
Thanks for the video. Informative. Question please; I can open the front facing panel of the compartment housing the fuse box. However I can't open the top cover as the silver button doesnt work, how do i remove this panel so I can acess the fuse? Cheers
The top panel are security locked by the vacuum system. You may have a damaged air line or pump. Check my other video on accessing the air pump in boot is under the roof pump. Does the other side open
@@GrooveOn hi, thanks so much for the reply and apologies for the delay. I managed to get my wife (who can actually fit into the space behind the seat) to pull out the fuse with a set of pliers. Pump reset and boot unlocked.
Since then have:
1. Aired the car
2. Silica gel in boot and behind drivers seat
3. Watched your 8x drains video and followed it
Car seems to work as normal. Roof functioning and central locking (with auto fold mirrors) seems to be working as before.
Next steps, remove some moulding on plastic trim that fold into the boot and the green mould from the bottom of the windows. Ideas most welcome please!
Then...maybe sell just before convertible season.
Thanks so much again!
Hi mate….what do you do if the compartment is locked and you do t have the zip tie? Do you just have to break the lock?
@@Azimkourah you can reach in from front with long nose pliers, try that
@@GrooveOnto remove the fuse or unlock the compartment?Thanks again
@@Azimkourah the front cover just pulls off it's just pushed in if you pull the fuse wait a couple of seconds and put it back in again. You can also unplug the pump at the back and plug it back in again if you can get in the trunk. If you look at my videos I explain about checking the electrical connection to make sure the contacts are clean
great video thanks - my trunk lid is stuck halfway open and halfway closed and the key does not turn the catch release - my door boot release has had problems and stopped working and my cubby is also locked so possibly the central locking is broken - any ideas how to get the cubby open without breaking the lock ? Do you think the fuse is the problem or will it be the pneumatic actuator ? many thanks for your help
If you lift the armrest there's two screws at the back remove these and the central peace between your cubbies can be removed. Underneath you will see the familiar yellow airlines just find the one that goes to your cubby and you might be able to force some air with an aerosol can down the tube
You can also remove the front panel of the cubbies and get to the fuse as I showed in the video with long nose pliers. One time my trunk was stuck half open half closed as I went over a pothole. I managed to resolve it by ensuring that the two flaps were fully up
@@GrooveOn Many Thanks for both suggestions , I have finally managed to open the trunk after 4 months and found the actuator pump now sitting in 2 inches of water following boot seal fail ( South UK is not supposed to have this much rain!!) I have dried it out and taken the pump assembly box to pieces to drain out the half cupful of water inside it - the motor is still whirring but it doesnt seem to have got the central locking working upon refitting the dried module (part of the circuit board looked as if it had been wet for a while and the 12 pin contact plug had blue copper sulfated on it which I scrubbed off)- I did manage to open the flap and suggested and check fuse which was ok. Any ideas what might still be at fault? not sure how I would test the PCB or hydraulic side of the pump assembly?
Having a similar problem, it's much better to remove the designated fuse rather than disconnect the battery - thanks for indicating the right fuse! What I find strange is that my problem is intermittent - it all works fine for a few operations then decides it isn't going to soft-close requiring a reset. I've had the lock mechanism out and detected no leaks - so what could the problem be?
If it works for a while and then stops you may find that the leak is very hard to see can you check it in situ? How long does the pump?
I have 2019 e300 any tips?
Thank You
Welcome
@@GrooveOn hi, thanks for your tip.i did a silly thing i pulled the fuse,but put it back in on the epmty space next door.what a wally..any tips on how to reset the roof and the starter motor.i paid over a thousand pounds for a rear sam unit.the car worked fine.the only thing that didnt work was the cd changer.so i started pulling out fuses ,and now the roof wont close and the car wont start..can you help me pleses???
Great video. Shall I do it with engine on or off?
Engine off, turn key so dash lights are on position 2, pull fuse wait for 15 secs, put back. Good luck let me know. 👍
Brilliant 👍
Thanks, I have just done a comprehensive video on how to remove actuator and fix you may like. ruclips.net/video/dPhSTnUtCdY/видео.htmlsi=strEdKoRDd3g1_sc
Those damn rear cubbies and the center console won't open on mine, blast!
I've had this happen, check 2 thing's, there is a electrical plug going into your PSU in the boot, make sure the pins are clean. If you can check the air pipes for kinks and holes. If you can lift the rear part of the trim between the storage harches you can access the pipes there also, there is a joint that you can undo and ouch air into. Watch my amplifier video I show how.
@@GrooveOn Thank you very much, I appreciate it.
My cls w219 opens with remote and manual, but when I lock the car the doors are locked but the trunk I still can open it manual so it's not locking
Check your actuator for leaks, airlines to it and where it exits the pump for leaks. ruclips.net/video/u21n8rccEZ4/видео.html. ruclips.net/video/dPhSTnUtCdY/видео.html
Is this something that can work multiple times?
Yes, it work multiple times, but you shouldn't have to, I would check for a leak in actuator, I created a video to show how
@@GrooveOn I just went to work on it but realized I didn't have the right epoxy, so i will have to try again in a few days. Just had to close the trunk in the mean time it seems pulling the fuse does the trick. Thank you for your helpful video
@@charliesilveria1998 there are a few places the actuator can leak, have a look at this video I show how to remove and fix. Let me know how it goes! ruclips.net/video/dPhSTnUtCdY/видео.html
should I disconnect the battery before pulling any fuses? would doing that make it adjust better with the system computer
No need to disconnect battery, just pull fuse wait 10 secs and put back mate
I can hear the hatchback trying to open, but it doesn't. Will this fix work for my problem?
Give it a try, there is no chance of harm
Can’t open my rear drivers side back passenger door 2:53 it’s stuck can you please help
Thanks
What car is that you have, the video is for Mercedes SL that are only 2 door.
Did you cut the bottom out of your storage compartment? Mine is all one piece and the only way to get it out is to unscrew the crews when you pull off that front trim piece.
Oh must be different to mine, there is a gap fortunately for me
@@GrooveOn Never mind I did figure where the seam was by popping the "floor" of the storage bin from the bottom. Thanks.
My top is down i open the trunk the top is suppose raise up but it want ehat wrong
Hi my switch inside the car doesn't work open the boot but it works off the key fob. I have a C CLASS 220D thanks
So if your remote works it works suggest your boot actuator is good, focus on switch, try spraying behind at contacts with WD40, might be dirty contacts,
Also check wire pin connection on boot lock are not dirty
I left my car key in trunk last night on slk 250 tried remove all fuses in engine compartment but nothing happened. I think my second fuse box is in the locked trunk 🤪
how can I disable the boot lid sensor which keeps coming up on the dashboard despite the boot being closed? car was involved in an accident in the past and had the boot door refitted before I bought it, i cannot afford to get the door replaced as its not worth it but need for this to go in order to go on a driving test. please help?
If you are referring to the internal compartment luggage cover, then just check the sensor at the right side, sometimes the wire connector is loose, see underneath. I wouldn't by pass the sensor as if you have something in the boot and lower the roof it could cause damage
@@GrooveOn sorry, I should have mentioned my car, its merc b class 2009 UK
@@mssz91 it's tricky to know mate, I do not have as much experience with B class. However what I would do is try MB world forum or Benz world.org
Will that work on a 2012 ML350? Please advise. Thank you 🙏
Hi there, if the ml has the same soft close set up, so long as you know the fuse I would very much hope so.
Hi, I've got a CLS 500 W219 do you believe that it will work? My trunk is stuck (opens only with key) Thanks
if it has the pneumatic set up then yes. The fuse may be different on yours, but the principle remains.
Hi Thank you for your video, I can not get into my two back storage compartments and my center consul is locked, all my central locking works etc, Please can you help?
Can you open the trunk? If so you may want to check the airlines going into the PSU pump. It sits under the power roof motor, which you can lift up on the frame by removing four 13mm nuts. The PSU pump sits beneath in a foam cover and lifts out. Check the air lines for leaks or kinks, I found one of my air lines was bent and prevented are flow to the rear hatches. Let me know how you get on.
@@GrooveOn Hi Thanks for your reply. I have only just purchased the car, I could open the boot but I decided to take out the Yellow 20 amp fuse you were talking about (which mine had a blue 15amp in?) but thinking it might reset it or at least unlock the compartments but it didnt and as it did not trying to put that fuse back in that way is a nightmare (well to me) i ended up dropping the two i had aaaahhhh!!! lol, I will get some more fuses and try to get one in then I can open the boot again. How fast should the door locks come up when you press your key fob? Mine seem quite slow against my other car? Could it be that the pump is not pumping enough air?
@@andrewlockyer1278 the doors should lock when you press the button in one second. You could have Leak in one of the airlines of it takes longer
@@andrewlockyer1278 @Giuseppe this is a classic tell tell sign you have cracks that are leaking are in your lock mechanism. I have another video that explains what to do.

@@GrooveOn Hi Thank you for all your help, I managed to get the fuse back in and the soft close boot worked for about 4 times now it does not work again and the rear compartments and center console are still locked? Like you say there must be a leak in the air lines somewhere? I am guessing its not the soft close boot bit other wise it would not have worked (even though it was only 4 times) I do not hear any air leaking anywhere? I guess I will have to take it to the Merc garage
I have a situation where I can't start my car after changing the battery, I think I blew out a fuse not sure where the fuse is ,nothing comes on please advise Thanks
Does the car turn over and crank? yes you may have inadvertently shorted a fuse when removing the cables, check under the hood fuse box too
Where can I find that fuse on a 2001 CLK430 ????
Hi There, I used to have a CLK W208 but not the convertible, loved it !.. Have you tried the main fuse box in engine?
I have an issue with a C220d AMG saloon, 2017, I drove the car 50 yards with boot open fully and now none of the boot opening device lift the boot lid fully and more annoyingly none close it at all. The internal switch will lift the lid about 4” as will the key or kicking under the bumper. What could be the issue here? Does it just require a reset?
It does sound like something has got confused, I would look into how to perform a reset. Do you have diagnostic device? Are there codes
@@GrooveOn sorry, don’t have diagnostics so no codes. Was hoping to find how to reset it when I stumbled onto your video.
@@TheSnowplough you could try unplugging battery, but you'll probably need to reset windows etc
How to do this on a W212 facelift?
Hi there, I believe your car is motorised not vacuum so the fuse reset will not help. Most likely you need to strip your tailgate lining and replace motor module.
don't like the idea of having the air locks so I unplugged both sides and put a screw in the hoses.
Mine isn't closing all the way
Then its likely you trunk actuator, very common fault, you can repair or replace, heres a video to help. ruclips.net/video/dPhSTnUtCdY/видео.html
