You're great, man! Thank you. We rarely can see something as good, easy-to-understand, professional material as this video of yours. Congrats! My W220 already loves you
I had an exact problem you addressed. My brother is a mechanic but Mercedes is not his specialty. I showed him this video. He changed the fuse and PSE pump and it worked. I god my car fixed last night and I am super happy. Thanks!
Glad to help 😊❤️ but keep in mind if the fuse blew you will need a new pse. It will happen again. Most likely due to an air leak and the pump running extra .
Yes, it's another EZ fix I would try spraying soapy water first on air hose leading to the strut under the hood, 2. the relay in the fuse box right side maybe bad, finally yes sometimes the hose on the pump can leak also I would buy another hose that's attached to the pump, shelf life with rubber is only 5 yrs. if that's leak most of the Mercedes problems are a EZ fix Mercedes likes to hide and tuck stuff it all a process of elemi nation car, a EZ fix.
I've had a 01 s430 for about 15 yrs and thought I watched ALL the videos on fixing and diagnosing the S class, after Watching this video, this guy is on point. Not only does he get to the specifics. He gives you the options and recaps. What you need to do, you are the man and Utilizing his checklist, it actually fixed my problem with my remote. Keep up the good work and look forward to more videos.
Thanks for prompt response. I forgot to state the day this door stopped functioning occurred at a car wash. i had just closed the door partly and then i witnessed it suction itself to close tight. Since then, i have not been able to get it to open. I will try banking from inside as you have suggested and hopefully it opens. Greatly appreciate the help.
This is awesome! You explained with depth and detail in a clear cohesive manner. I wish you could repair my S350. I am so tired of having it repaired by "hit or miss" claiming to be experts at servicing Mercedes Benz automobiles. I will continue to watch you for my own level of knowledge about my vehicle. You are a rarity.
I went through this with my 95 R 129 Conv. top's 10 actuators, now this 03 SL500 has a whole new set of challenges. Getting the retractable top to operate is dependent on each feature in a sequence to operate flawlessly and although I can move top, my central locking pump is running but mechanisms are "not" moving, so your video has opened my eyes and I am most grateful, thanks
Great video, I had to replace all my pneumatic actuators on all four doors and trunk. After age the diaphragm will crack hot and cold weather will do it. Also bought a new PSE pump too. There are no way around it. W220 will all have this issue after a decade easy. Great diagnosis here, thanks for the video
Thanks for the video! I've got a 2000 s430 with only 40k miles. The car is practically spotless. It's been in storage for years. Of course the locks are defunct like a lot of other shit on this car. Found PSE fuse blown. Pulled PSE and opened for inspection. Looked like day 1 inside that thing. Whacked it a couple of times with 12volts and the pump came alive. Replaced the fuse and it's working, hope it stays that way! Now if I could just get the stupid air compressor to come alive when the car needs it, I might actually be able to drive this car. I swear it's the nicest POS you have ever seen. Total time capsule.

Thats a great idea. I hear there are some rent a rack businesses . That was an idea that I had as well as many people would love to do some things themselves but they dont have the rack or required tools.
Thanks for the video. I have a 2000 S500 central locking wouldn’t work, soft closed doors wouldn’t work, boot wouldn’t open with button or key fob. Fuse kept blowing on the old pump I purchased a second hand pump for £250 and everything has started working.
Mine started act weird, will work sometimes, sometimes no. But what I found is separate electronic components like parking mode dash cam power supply, led lights. This type of behavior was described in newer pickup trucks after installation of led backup lights.
Hey i think you just saved my day! Ive got a 2005 s500 and ive got some very disturbing issues. So lets start: Central locking works only front doors.Trunk works. Headrest falling works. Buttons on dash dont work. Soft close don't work. Everything work except the buttons on the dash and the rear doors and the soft close .I hear a buzzing sound from the back if I press the buttons on the dash but nothing happens. I think the previous owner switched the PSE from a CL. Thats the only thing i could believe.....?
What an awesome job, hopefully, you can help with my 2004 S430 W220. 2 issues, the trunk won't open, and based on this video, it sounds like it is the PSE that is leaking; the close function works great. Second issue and what I really need help with: My Head unit has the following message: "Flash drive system will be formatted. All user data lost. It could take up to 5 minutes. Please do not switch off!" How can I get the radio to work again.
If memory serves there might be a software update that the dealer needs to do or the radio will need to be replaced. The issue is the internal processor is corrupted or something
Thanks Lou, Drivers side Soft isn’t working but all others are. My drivers seat isn’t so I am hoping this will fix it! Thanks excellent video short and to the point. Cheers
Once you pull and reinsert the fuse it will work again. Put your ear to the door handle and you will hear the leak and or in the door jamb area where the line flexes.
@@MasterTechLou It did just what you said, I heard the Hissing, is that where the leak is? I just have to take off the door panel and fix the leak? Thank you for the Help
Hey buddy nice video. I have a 2004 S55 my Doors Not Open everything is working inside softclose trunk. But i cant Open it with the key… what could it be ? Maybe door control Unit ? Keyless start is also working when i open car with key..
As for the pump - I saw a kit to rebuild a vacuum part of the assembly. It is graphite parts, there's plenty of videos on TH-cam on how to do, how to test with the pressure meter, because you regulate with bolts pressure of the assembly and as it's a graphite - you can destroy it...
Good to know! I want to help a friend with a 2001 S500 5.0 My friend doesn't have money, and he's 82yrs old, but a cool dude. I'm also taking the CD changer out of my 05 C240, and putting it the spot in his trunk where the existing changer stopped working, and he can't get the CD out of his dash. I won't ever use the changer because for the most part, I stream. But I saved your channel. 👍
FYI S”500” means 5.0 The badging is the engine size. Of course not all are consistent because they started to account for a turbo or supercharger so like a 1.8l could be labeled a 230. But all numbers on the back of a Mercedes are the engine size. Whether it be natural or forced.
@@MasterTechLou It's def a 5.0. But I'm sure the wiring is the same. He'll get my CD changer into his trunk. Gonna help him fix his keyless entry. Gonna do my homework and help his car be 100%.
DAMNIT. loli just ordered an entirely new PSE on my s600. Good news knowing I can just swap motors in the future.i have a couple softclose issues on mine.
#78 fuse (fnt passenger side) blows when I put a new one. My key will not turn, won't lock/unlock doors/trunk. The trunk unlocks from the rear & from inside the car. I've checked all the fuses under the rear seat & all were good. I'm STUCK! This video didn't address my SPECIFIC problem, but I LIKED & SUBSCRIBED anyway because I like the way you hold class. GREAT VIDEO. Any help on my specific issue? As a browse through your videos hoping to find the solution. THANK YOU
@@MasterTechLou Actually I followed other advice and disconnected the "Alarm Siren" which turned out to be a charm. I inserted the fuse, and it's working just fine.
Thanks for this video. I greatly appreciate you. I have a 2000 S500 and the left rear door will not open at all from inside or outside. The truck will not open with the remote but only with the key. Help!
Help, ok so , make sure the key slot is vertical not horizontal. Read the owners manual on “valet mode” and youll see why. That can be why. Or a leak. As for the door, latch is most likely rusty. Only fix is pull both door handles and whoever is on the inside just keep banging on door. I have seen sticking latches and I have seen sticking door seals. Crazy how a door seal can keep a door from opening. Best of luck
Liked and Subscribed. I just purchased a 2006 S430 with 45k miles knowing the PSE was bad. My new pump came today and it took about 5 minutes to install. Nothing works. I can hear the pump whirring when I push the lock or unlock buttons but the locks don't move. I've tried pulling the (perfectly good) fuse. Still nothing but the whirring. Any suggestions?
Awesome video! Very detailed and informative. Thank you so much. But check this out , I checked mine and found a 20 amp fuse still perfect? I pray once I change it that’ll fix my problem.
Fix your problem? Probably not. But the video explains it will reset the pump and allow it to work until fault codes trip again. A good fuse does not mean a good pump. Just means a good fuse 🤷🏼♂️. Best of luck 🤞🏻
Lou I have a 2004 s55 with 75000 miles engine running good but lately electrical problems trunk not unlocking via key or trunk button i was told i need new actuator ?? Additionally, my battery went dead had AAA put in new one and head lights will not shut off before this the radio would sometimes not work but then when driving for a while it comes back on is this a control module issue and if so can is it something a DIY could do
Anyone can diy with the right scanner, patience and access to how the systems work. Like I said in the video pull the fuse. Put it back in. If the trunk now works it’s because you do have a leak. As for lights, check your front left fuse box cover, hope its not loose and water didnt get in there. As for radio, they fail often. So may need a new one.
I'd be pretty reluctant to use a used' pump. You don't know the miles of the car it came off of, or how long it has been sitting. In my 95 f150, the Hvac used a vacuum system like this to actuate the vents-- and I always hated it. I'm shocked to see these cars use such an extensive vacuum system like this. There's just too many points of failure IMO.
Hey Lou, great video! I have inherited a mint 2003 S500 4matic with 29k on it that is having a issue with the trunk open and close. All of the soft close work on the whole car, including the trunk. How can I check was is causing the power assist not to open up or close down? Thanks
Need a scanner. Also open the trunk all the way, press and hold the close button until the car dings. Usually takes about 10 seconds. Then see if the trunk works. If not, it can be a number of things wrong.
Hey ty. One question. Three door was working except 1 with sucking system. When i ised this door it sounded like something broke inside. And then the door is locked now. The rest are working except this one . Need to change the pump?ty
Lou, thank you for all you do. I have a. 2002 S55. All of the buttons on dash don't work for some reason....including ABS, shades etc....could the ABS module be culprit or what do you think...?
The situation I'm having is that the keyfob works fine. The central locking via the button on the center console locks and unlocks all doors except the FL passenger door. If I use my scan too to do the same, it works fine.
I have my driver door lock and soft stop closing. everything else works. well passenger lock works sometimes but soft close works. my car is a 2003 cl55 amg . fuse is good but scan tool reading all the codes in the PSE so now based on your video im thinking the pump is bad thank you.
Thank you for this video! No joke this is one of the most clear and precise informative videos I've watched on the w220. Do you by chance happen to have a video or instructions on how to install the radio fin antenna cover?
Question, I hope someone who has an answer will respond to this. My car is a Mercedes-Benz S430, similar to this. The battery went out, then I charged it. After that, the right seat, the right mirror, the horn, and the right window went out. What is the reason? Or is there something separate or a fuse that needs to be replaced?
@@Hjaji0 this is most likely a coincidence. The problem lies in your door module. Either the wire in the door jamb is broken or the fuse to the module blew.
GUYS IF YOU CAN LOCK AND UNLOCK THE CAR FROM INSIDE BUTTONS ON THE DASH, BUT THE KEY IS NOT LOCKING AND UNLOCKING THE CAR IT CAN BE FUSE 60 7.5 amp.(located under rear right seat) FOR ANTENNA BOOSTER AND PROBALY IT IS, CHECK IT
I have an Italian electric car certificate and I recently purchased this car in Ukraine where I am trapped due to the war, after less than a week the local police stopped me and they literally kidnapped me with the intention of seizing this "super 5 liter car" from me "but I managed to escape and during the chase I broke two wheels and the internal bumper and also the lock of both the keys and the button inside no longer works, which is important for me so as not to get kidnapped by the local police again, I have already tested the fuses and they work now I will try to check the pump and thank you very much for this video
I’m gonna try the pump issue and the fuse. My locks/trunk/door suction not working. Also, my key won’t turn, I’ve been having issues with needing to jump my car so I purchased a new battery but it still periodically will need to be jumped. My key won’t turn but all my interior lights are on. My alarm button isn’t working but my unlock alarm button works. Help!,,,
Hi, I have a w220 2004 s500 4 Matic 5l v8 engine and my teleaid malfunction drive to the nearest dealer is on. how can I clear it and what obd code reader will clear it. thank you.
Hello, I have a problem with opening the MB W220 500S 4 Matic, when the temperature drops below zero, I replaced the batteries in the key, the battery is new, when the car warms up, it opens without any problems I DON'T KNOW WHAT TO DO HOW TO SOLVE THE PROBLEM, ANY HINT?
obviously temperature related. in this instance I use a heat gun to warm up whatever module I need to focus on. and or put a module in the freezer to get the issue to happen on purpose.
This symptom happens a lot after a car has suffered from a flat battery... I am going to guess that Jump starting the car blows the Locking fuse.? I don't have this model with the pneumaticx.
not in my experience no, jump starting the battery should have no effect on just the lock pump, that would be very odd that it would be the only fuse that blew. the only time that fuse blows is due to a bad motor. if it blew once it will definitely blow a second time. if the pump even works after installing the fuse.
My 01 s500 The only door that unlocks is the passenger side front. The trunk won't pop unless I use the key. Then I hear air hissing from around the Latch area when I do open it. None of the soft doors work except for the passenger sign and the postfeature doesn't work on any of my seats. U think this is the pse? The fuse was fine and the hoses are red not yellow
Most likely you have every element failed. Soft close will not work if locks wont work. Could also be pse not activating the solenoids for each branch. Will need more diagnostics done
Thank you for such a prompt response. The information was very helpful, but I replaced the old pump which had literally melted to the casing. I installed a used pump that runs but still have the same problem. I would be very grateful for any further information. Should I get a new or rebuilt model. Thank you so much
Our cars didnt start making a lock or unlock sound until certain models. And if they can, the setting is in the dash. Some if memory serves needed to be turned off with a scanner but the beeps didnt start until w211 and w203 chassis I think.
Why does my trunk do that what is wrong with the trunk latch ?.also my lock with my key only works from my door handle but far away it doesn't I replaced then rear headliner antenna for door lock it didn't fix problem because I think I need a new rear window because the pads touch the glass and the connection is around the glass are not that great is it just the glass??? Also when I use my air ride buttons they work and then when I go to use them again to change setting they just stay lite up red and don't allow me to change them smh.
Also A/c is hot on the half end of the car (co driver) & cold on the Driver side, my w220 is with climate control; whats the problem there pls? Is it a fan or a fuse? It aint the cooling gas level, thats ok…thank you!
When I switch the pump out and put another used one in it work for about two days deluxe inside the car and the trunk everything work after two days all I hear now is a whispering coming through trunk I pull a fuse out and put it back in to reset the system all I hear is up
@@joem.575 ok gotcha, if you mean NEW as in NEW from dealer, you can part warranty it. if you mean new as in used, you may have just gotten a bad pump. they dont burn out quickly, also once you replace it you can check every door with soft close and trunk soft close and locking and unlocking and listen for the leak its typically easy to find.
@@moemado8871 ok you most likely lost synchronization. Start the car. Pull the switch DOWN and hold it, it should move the glass closed and then it should open the vent. Once it does, pull it down again to close it and it should work 1 touch.
I have a 2005 S430. The truck won't open with the key fob, or from the driver side door latch (only with the key). Door locks do not work from key fob, or the dash buttons. However, from the fob, when I press lock, the alarm sets and if you open the doors the alarm goes off until you press unlock on the key fob. Also, the soft close doors do not work. I changed the fuse, but it didn't change anything. Help?
hoses tend to break where they bend, like in between doors, and trunk lid hinge. you can use a smoke machine, trick is cant put too much air pressure as if you test the wrong line it can blow the air element.
Have a question I have a 06 s430 and when I press trunk open on remote it tries to raise but the lock doesn't open. I changed puck, and same result. When I use key to unlock trunk then use trunk open inside the car, it raises but I had to manually open it. Any suggestions ?
The lock is operated by the air from the pse . If there was a leak at one time the pse will stop air to that circuit. Youll have to pull the fuse just like I mentioned in the video.
I have issue with my 2000 S500 my windows don’t work dash lights and front power seats don’t work what could be the issues someone told me it’s part called sam that control all that can any one point me in the right direction
only thing I can advise is getting a scanner and reading all the codes to see what the codes are and then finding out if all modules are communicating. However if you do not know all the modules that should be communicating then it will not help you. The right direction is to not assume what can control all the items, but to have someone with Mercedes specific knowledge scan the car and get an assessment of what's happened. I looked at the wiring and the only correlation between what's happening is the data communication system, not a fuse.
i have a 2008 E350 after i park my car it wont lock or open doors or trunk, and my car is not starting any more the key dosent open the ignition switch any more, any help where to check next will be apreciated i already check hood and trunk fusss they are ok thanks in advance
@@MasterTechLou thanks for ur reply, i think is the key that fail, cause i put a new batterie on the car and also the key. and the system works cause i can open the doors and trunk with the botoms inside the car so most like is gone be the key thanks for ur help 🙏🙏🙏
Hey sorry to hear. 😔 . There could be a number of reasons why this could happen. The most common Is a failed steering lock. But there can be so many reasons for this. All I can say from here is that theres nothing that can be done to force a mercedes to start. So its gonna have to be towed to a shop or mechanic with Mercedes capable scanners and experience.
Here's a interesting one : keys ok , all fueses and relays ok , battery very ok, nothing works just hazards flashing fast , no ignition life(as in ignition not releasing when key inserting) with either keys so impossible to use diags ....
You say interesting I say symptoms. When you insert the key the transmission is strictly between the key and ignition switch. So if it wont unlock the issue is either the key or ignition switch. If you try 2 keys and still No go, then its ignition switch failure provided that you confirm power and ground to the switch.
@@fernandoruiz2596 no you cannot they are vin coded. Youll have to have the dealer replace it. Or find someone that can overwrite a used one with your vin.
My key must be broke everything else cool but key do not unlock or lock at all. Everything else works . Key turns on car and all .. push to start on shifter does not work either.
Wellllll. I have discovered that it is a little more difficult to get out than your video shows when your motor has completely melted the plastic housing and the carpet padding that's around it hahaha

Thanks for this video. I greatly appreciate you. I have a 2000 S500 and the left rear door will not open at all from inside or outside. The truck will not open with the remote but only with the key. Help!
Help, ok so , make sure the key slot is vertical not horizontal. Read the owners manual on “valet mode” and youll see why. That can be why. Or a leak. As for the door, latch is most likely rusty. Only fix is pull both door handles and whoever is on the inside just keep banging on door. I have seen sticking latches and I have seen sticking door seals. Crazy how a door seal can keep a door from opening. Best of luck
Liked and Subscribed. I just purchased a 2006 S430 with 45k miles knowing the PSE was bad. My new pump came today and it took about 5 minutes to install. Nothing works. I can hear the pump whirring when I push the lock or unlock buttons but the locks don't move. I've tried pulling the (perfectly good) fuse. Still nothing but the whirring. Any suggestions?
Bad pump , clogged inlet line, or massive leaks everywhere. All answers are in the video
Awesome video! Very detailed and informative. Thank you so much. But check this out , I checked mine and found a 20 amp fuse still perfect? I pray once I change it that’ll fix my problem.
Fix your problem? Probably not. But the video explains it will reset the pump and allow it to work until fault codes trip again. A good fuse does not mean a good pump. Just means a good fuse 🤷🏼♂️. Best of luck 🤞🏻
Hi
Do you have any videos on mercedes diagram ?
On how to read them and what the symbols mean
Lou I have a 2004 s55 with 75000 miles engine running good but lately electrical problems trunk not unlocking via key or trunk button i was told i need new actuator ?? Additionally, my battery went dead had AAA put in new one and head lights will not shut off before this the radio would sometimes not work but then when driving for a while it comes back on is this a control module issue and if so can is it something a DIY could do
Anyone can diy with the right scanner, patience and access to how the systems work. Like I said in the video pull the fuse. Put it back in. If the trunk now works it’s because you do have a leak. As for lights, check your front left fuse box cover, hope its not loose and water didnt get in there. As for radio, they fail often. So may need a new one.
@@MasterTechLou
Thanks
I'd be pretty reluctant to use a used' pump. You don't know the miles of the car it came off of, or how long it has been sitting. In my 95 f150, the Hvac used a vacuum system like this to actuate the vents-- and I always hated it. I'm shocked to see these cars use such an extensive vacuum system like this. There's just too many points of failure IMO.
Hey Lou, great video! I have inherited a mint 2003 S500 4matic with 29k on it that is having a issue with the trunk open and close. All of the soft close work on the whole car, including the trunk. How can I check was is causing the power assist not to open up or close down? Thanks
Need a scanner. Also open the trunk all the way, press and hold the close button until the car dings. Usually takes about 10 seconds. Then see if the trunk works.
If not, it can be a number of things wrong.
I’ll give it a try. Thanks @@MasterTechLou
Hey ty. One question. Three door was working except 1 with sucking system. When i ised this door it sounded like something broke inside. And then the door is locked now. The rest are working except this one . Need to change the pump?ty
Lou, thank you for all you do. I have a. 2002 S55. All of the buttons on dash don't work for some reason....including ABS, shades etc....could the ABS module be culprit or what do you think...?
Its called an upper control panel. And fails often. All the buttons are part of one panel.
@@MasterTechLou OK. Thank you so much Lou!
The situation I'm having is that the keyfob works fine. The central locking via the button on the center console locks and unlocks all doors except the FL passenger door. If I use my scan too to do the same, it works fine.
Thank you for sharing this knowledge!
I have my driver door lock and soft stop closing. everything else works. well passenger lock works sometimes but soft close works. my car is a 2003 cl55 amg . fuse is good but scan tool reading all the codes in the PSE so now based on your video im thinking the pump is bad thank you.
Most likely line is cracked in the door jamb or the lock element is leaking.
But if you do have codes for every circuit then yes most likely weak pump
lou you might be right i do hear air leaking in the door jamb area an issing sound after i turn the car off @@MasterTechLou
when i clear the code with my autel scanner all 6 codes came back@@MasterTechLou
Thank you for this video! No joke this is one of the most clear and precise informative videos I've watched on the w220. Do you by chance happen to have a video or instructions on how to install the radio fin antenna cover?
Thank you 😊 and my apologies I do not have a video . If you find me on instagram I may be able to get instructions for the fin.
@@MasterTechLou your IG handle the same? Half these other folk explaining the how to confuse me! You never left a question in my head!
Question, I hope someone who has an answer will respond to this. My car is a Mercedes-Benz S430, similar to this. The battery went out, then I charged it. After that, the right seat, the right mirror, the horn, and the right window went out. What is the reason? Or is there something separate or a fuse that needs to be replaced?
@@Hjaji0 this is most likely a coincidence. The problem lies in your door module. Either the wire in the door jamb is broken or the fuse to the module blew.
GUYS IF YOU CAN LOCK AND UNLOCK THE CAR FROM INSIDE BUTTONS ON THE DASH, BUT THE KEY IS NOT LOCKING AND UNLOCKING THE CAR IT CAN BE FUSE 60 7.5 amp.(located under rear right seat) FOR ANTENNA BOOSTER AND PROBALY IT IS, CHECK IT
Thanks!
I have an Italian electric car certificate and I recently purchased this car in Ukraine where I am trapped due to the war, after less than a week the local police stopped me and they literally kidnapped me with the intention of seizing this "super 5 liter car" from me "but I managed to escape and during the chase I broke two wheels and the internal bumper and also the lock of both the keys and the button inside no longer works, which is important for me so as not to get kidnapped by the local police again, I have already tested the fuses and they work now I will try to check the pump and thank you very much for this video
You really escaped from the local Police? 😮
Bro thank you so much it’s been sitting here for months finally on and you said what I’d bad the pc something is bad I couldn’t hear
Pse
On my 2006 S500 the driver door wont lock or self close. Every other works fine, what could it be??
In W220, Battery's condition is very important, and weak will affect many functions
absolutely
You tell it perfect. I will try stap stap what you all saied. Thank u man👍🏼
I’m gonna try the pump issue and the fuse. My locks/trunk/door suction not working.
Also, my key won’t turn, I’ve been having issues with needing to jump my car so I purchased a new battery but it still periodically will need to be jumped. My key won’t turn but all my interior lights are on. My alarm button isn’t working but my unlock alarm button works. Help!,,,
Hi, I have a w220 2004 s500 4 Matic 5l v8 engine and my teleaid malfunction drive to the nearest dealer is on. how can I clear it and what obd code reader will clear it. thank you.
Hello, I have a problem with opening the MB W220 500S 4 Matic, when the temperature drops below zero, I replaced the batteries in the key, the battery is new, when the car warms up, it opens without any problems I DON'T KNOW WHAT TO DO HOW TO SOLVE THE PROBLEM, ANY HINT?
obviously temperature related. in this instance I use a heat gun to warm up whatever module I need to focus on. and or put a module in the freezer to get the issue to happen on purpose.
This symptom happens a lot after a car has suffered from a flat battery... I am going to guess that Jump starting the car blows the Locking fuse.?
I don't have this model with the pneumaticx.
not in my experience no, jump starting the battery should have no effect on just the lock pump, that would be very odd that it would be the only fuse that blew. the only time that fuse blows is due to a bad motor. if it blew once it will definitely blow a second time. if the pump even works after installing the fuse.
My 01 s500 The only door that unlocks is the passenger side front. The trunk won't pop unless I use the key. Then I hear air hissing from around the Latch area when I do open it. None of the soft doors work except for the passenger sign and the postfeature doesn't work on any of my seats. U think this is the pse? The fuse was fine and the hoses are red not yellow
Most likely you have every element failed. Soft close will not work if locks wont work. Could also be pse not activating the solenoids for each branch. Will need more diagnostics done
Wow, awesome vid, thank you!!
Thank you!
Great info.Thank you for all the tips, I hope that fix the issue on my s500, good bless you.
Did you tried that?
What if battery on key is good (new battery), doors lock from button on dash, fuses are good, but lights nor locks respond to the key?
Video shows everything. Bad key
Thank you for this video. Very helpful 👌
So Mastertech Lou where is the relay for the SRS on a06S 55 AMG?
SRS does not work off of relays.
@@MasterTechLou OK thank you.
Hello Master Tech
What is the issue if the pump continues to run, but doors still don't work
Pump cant build pressure or
Vacuum itself. Bad pump. Most likely culprit
Thank you for such a prompt response. The information was very helpful, but I replaced the old pump which had literally melted to the casing. I installed a used pump that runs but still have the same problem. I would be very grateful for any further information. Should I get a new or rebuilt model. Thank you so much
How to make it make noise when you hit lock button… any way to take it off from quiet mode?
Our cars didnt start making a lock or unlock sound until certain models. And if they can, the setting is in the dash. Some if memory serves needed to be turned off with a scanner but the beeps didnt start until w211 and w203 chassis I think.
Hi, I have 2007 Mercedes S550, I could not locate the PSE Central locking on the left of my trunk. Please help. Thank you in advance.
I don’t know how I can help when the video clearly shows the location? Thats the best help I can provide.
Well I can tell you if you have an S550 then its not this same car. So you don’t have the same system. This model didnt offer a 550.
What if the lights don't work when you press the key but the dash lock works?
Why does my trunk do that what is wrong with the trunk latch ?.also my lock with my key only works from my door handle but far away it doesn't I replaced then rear headliner antenna for door lock it didn't fix problem because I think I need a new rear window because the pads touch the glass and the connection is around the glass are not that great is it just the glass???
Also when I use my air ride buttons they work and then when I go to use them again to change setting they just stay lite up red and don't allow me to change them smh.
How did you PSE box to check the ground wire?
Small screwdrivers. The case just pops and snaps together.
Also A/c is hot on the half end of the car (co driver) & cold on the Driver side, my w220 is with climate control; whats the problem there pls? Is it a fan or a fuse? It aint the cooling gas level, thats ok…thank you!
When I switch the pump out and put another used one in it work for about two days deluxe inside the car and the trunk everything work after two days all I hear now is a whispering coming through trunk I pull a fuse out and put it back in to reset the system all I hear is up
My lights work when I use my key but now it won’t turn the ignition. I also don’t see the infa - red light on the end of the remote
I’ve had an issue where when I put a new pump in and the pump instantly burned out… I’ve checked fuses and wiring but no luck… suggestions?
new pump only? like replaced just the pump inside the pse housing?
@@MasterTechLou the whole unit. I’m suspecting maybe a leak in the hosing which maybe causes it to constantly run.
@@joem.575 ok gotcha, if you mean NEW as in NEW from dealer, you can part warranty it. if you mean new as in used, you may have just gotten a bad pump. they dont burn out quickly, also once you replace it you can check every door with soft close and trunk soft close and locking and unlocking and listen for the leak its typically easy to find.
hey i had blown fuze. i fixed the motor wire and the pump works now but still my locks and soft close doesnt work what do i do
Probably bad PSE. Cant build vacuum or pressure.
Can u please make a video on the roof doesn't open and close from the 1st click to the roof botton
You mean 1 button express open and close?
@@MasterTechLou yes
@@moemado8871 ok you most likely lost synchronization. Start the car. Pull the switch DOWN and hold it, it should move the glass closed and then it should open the vent. Once it does, pull it down again to close it and it should work 1 touch.
@@MasterTechLou
It worked 💪 thanksss
@@moemado8871 tech tip, it may even show that in the owners manual 😉
I have a 2005 S430. The truck won't open with the key fob, or from the driver side door latch (only with the key). Door locks do not work from key fob, or the dash buttons. However, from the fob, when I press lock, the alarm sets and if you open the doors the alarm goes off until you press unlock on the key fob. Also, the soft close doors do not work. I changed the fuse, but it didn't change anything. Help?
Would you say the problem is more than likely the Central Locking Pump in the trunk?
Forgive me. But the video clearly explains everything you just asked me. I hope it helps.
Thank you sir.
Is there an exact way to find the leak in the air hoses?
hoses tend to break where they bend, like in between doors, and trunk lid hinge.
you can use a smoke machine, trick is cant put too much air pressure as if you test the wrong line it can blow the air element.
Hey I’m having a issue with the key not turning in my 04 s500 4 matic Mercedes-Benz can’t start the car… what is this?
Hey, sorry to hear.
Car battery
Ignition switch
Blown ignition switch fuse
Bad key.
I hope it works out for you. Lou
Have a question I have a 06 s430 and when I press trunk open on remote it tries to raise but the lock doesn't open. I changed puck, and same result. When I use key to unlock trunk then use trunk open inside the car, it raises but I had to manually open it. Any suggestions ?
The lock is operated by the air from the pse . If there was a leak at one time the pse will stop air to that circuit. Youll have to pull the fuse just like I mentioned in the video.
Is there a length of time having fuse out ? Because I tried that and it didn't work. And thank you for quick response
@@tomkat2803 then you most likely have massive leak or assembly is rusted stuck
bro i literally love you rock
Have to buy me dinner before you drop the L word……. 😂😇 I hope this helped you.
Hi i have S55 2002 gauge's mileage doest work the screen become red any solution for this issue ...Regards
new cluster,. these were problematic . either find someone to repair or buy new/used.
@MasterTechLou Hi I changed the gauge & I transferred the old mileage to the new one. Thanks
I have issue with my 2000 S500 my windows don’t work dash lights and front power seats don’t work what could be the issues someone told me it’s part called sam that control all that can any one point me in the right direction
only thing I can advise is getting a scanner and reading all the codes to see what the codes are and then finding out if all modules are communicating. However if you do not know all the modules that should be communicating then it will not help you. The right direction is to not assume what can control all the items, but to have someone with Mercedes specific knowledge scan the car and get an assessment of what's happened. I looked at the wiring and the only correlation between what's happening is the data communication system, not a fuse.
Thank you

Hey currently experiencing my Mercedes Benz c300 locked in drive. I can’t drive or put it in park or neutral. It won’t start. Please help
Hey sorry to hear. 😔 . There could be a number of reasons why this could happen. The most common Is a failed steering lock. But there can be so many reasons for this. All I can say from here is that theres nothing that can be done to force a mercedes to start. So its gonna have to be towed to a shop or mechanic with Mercedes capable scanners and experience.
Does this translate to a Clk240?
I had a transmission conductor plate put on now my car not moving nor key unlock door help

hi my radio is locked how can i unlocked
Radio code cards should have been in glove box. If not we use either the vin or radio serial number to get
The codes at the dealer
Here's a interesting one : keys ok , all fueses and relays ok , battery very ok, nothing works just hazards flashing fast , no ignition life(as in ignition not releasing when key inserting) with either keys so impossible to use diags ....
You say interesting I say symptoms. When you insert the key the transmission is strictly between the key and ignition switch. So if it wont unlock the issue is either the key or ignition switch. If you try 2 keys and still
No go, then its ignition switch failure provided that you confirm power and ground to the switch.
@@MasterTechLou was EIS fuse ....just very hard to spot ....
@@freenergyterminator glad it was that easy!
However if it blew once it will
Blow again so keep that in mind
@@fernandoruiz2596 no you cannot they are vin coded. Youll have to have the dealer replace it. Or find someone that can overwrite a used one with your vin.

Man i wish you could just pull out the pse like you did, but nope it doesnt come out like that.
Not sure what you mean. Literally takes under 5 min to access and remove 🤷🏼♂️
@@MasterTechLou hmm okay maybe it just takes a little more finagling to get it out
@@2857steve you use a flatblade screw driver to pop each grey rail that holds all the yellow lines together. Gently. Then the pse slides out

Wellllll. I have discovered that it is a little more difficult to get out than your video shows when your motor has completely melted the plastic housing and the carpet padding that's around it hahaha
