Awesome video! Thank you so much, I replaced all the air bags on my GL450 and was wondering where the filter on the pump was. This helped me. You know everything is a big secret at Mercedes, thank you again.
+Tom B I appreciate the feedback... definitely agree with you on the mercedes secrecy.... makes it hard to keep the car running perfectly if dealership doesn't share any info
Great video! I had the same problem! My compressor inlet hose also had broken at the elbow. The Dealer wanted to replace the air springs but that did not make any sense to me since it was not a consistent problem. The valve block caused the random "front down" / "rear down" / "all down" issue I was having. Thanks for posting!
That inlet port on the pump also acts as the exhaust port when it's blowing off excess pressure. If that hose is popped off, you'll notice the compressor is very loud both running and blowing off excess. You can always nip the end off the hose that connects to the pump, use an extension fitting, and just run a new portion of hose. The hose/filter combo runs about $150 so just replacing the broken bits is quite a bit cheaper. Buying a new filter and swapping that in (if you want) is also less than $10.
Is it possible to replace just the inlet hose? I had the same issue and I cut it back and reconnected but a few months later the end dried up and crumbled again. I replaced the filter and the rest looks fine so it seems silly to spend $150 on the whole assembly when I just need the hose replaced.
My Gl450 was in the same shape the hose was broken at the bend so I just cut that bit off, got a new filter on Amazon for $10 or whatever and put it all back. It's a shame Mercedes did not use a metal piece or hard plastic for the bend that seems to be a very weak point on so many videos.
Awesome video now I think I know why my front right is dropping because the same thing. All the airbags were replace the compressor was replaced. Because the same thing all the airbags were replace the compressor was replaced but I don't know about that filter filter deafly gonna start their definitely gonna start there
To remove the valve block, do you just remove the compressor and it comes with it? Is there enough slack to change the hoses while under the car or did you clip the lines to remove the old block first?
Exact same issue I have with my 2005 W220 s320cdi, every so often after not being driven for 2-3 days the drivers side front seems to sink, if left longer it comes up on dash, do not drive take to workshop etc. 2 specialists have give me 2 Separate issues, 1. Compressor, 2. Strut but both no don't know for sure and obviously there is an expense involved which I want to avoid. Should I suggest the Mann filter change first or valve change or clean ? I love my 18 year old car without the latest TV screens which I absolutely hate !! Thanks
So I just bought a used 2012 cls550 4matic. I noticed that my suspension is kind of rough rather than smooth air ride. When I hit a bump the rear wheel would shift awkwardly. And I also noticed the compressor hissing from the rear while I'm driving and when i park it in my garage. Please help
Thank you for the video. I need to change that on my GL450 so I was wondering after I leave please that valve does he need to go on the computer to do any adjustment
2010 gl 450 air suspension on all 4 sides are down...i check all fuses and relay are good...i change the pump also...the Benz wont let me communicate with the air suspension. When the past i used that scanner plenty of time to do work on the car...what should i be looking for
super video .. I have a Porsche Cayenne 2011 mod ... and I have problems :-) The car loses pressure on one wheel, sometimes on two, sometimes the rear wheels lift into the air and block everything ... sometimes everything is fine .. I bought that box with valves to change .. People tell me I can't do it alone because nitrogen is used in the system. How? when I also found a pipe that goes to the engine from the compressor .. which probably takes air ..
Boss! this is very very very very helpful!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! thank you so much.. I was dying to see something as helpful. I just have a question very similar to what you have: Immediately after turning off the car .. I hear hiss sound and the front drops by like an inch or a little more.. it looks ugly!!! it is symmetrical but ugly .. where do you think the origin of the issue is? should I just change the filter you had in your hand? if I put soap on the body of the strut and find no air.. does it exclude a bad bladder issue? how do you check for the rear ones.. thanks again
I have sort of similar issue when I park my car GL 550 2009, I hear the air releasing also when driving with open windows slow I can hear on every bump on the road or when I press breaks air releasing but my car stays same height but this makes compressor works, would replacing the filter resolve my issue if not can you guide me what should I do next
Is that really the air intake hose/to filter? I replaced mine yesterday, and while it was up in the air, I started the GL, the air compressor seemed to be pushing air OUT of the hose and into the filter. Again, with the hose DETACHED, it was pushing air OUT? I was so confused why it is pushing and into the filter and then out to atmosphere.
Another common problem on this system is wiring. Inspect your wiring. Mercedes ran it too taut, and with movement creates chafing which leads to shorts and open circuits. If I had a 💵 for every time a valve block was changed, and it was actually the wiring.
My car rides bumpy sometimes change the compressor valve block realy there is no leak from shocks and the delear saw no messages could it be the filter
I’m no expert in the field, but have had a ML280 and now a GL320. The compressor on the ML when I first got it started making awful noise .. I changed it as it was the stock one (same compressor for 13 years..!) and now with the GL I had no problems so far as most of the airmatic stuff has been changed. Now in your case it can sound like the filter.. if nothing leaks and everything else is fine; that meaning also airlines are ok and in good shape, possibly your filter. I’ve learned with airmatic that it’s ruling out stuff and checking what works and what doesn’t 👍🏻 Hope this helps dude. I’m on constant search for videos to learn more about airmatic as it’s v pricy (especially here in Norway) and to be on top of the game I find it important to learn as much as I can about it as I love my GL and how these cars are 👍🏻👍🏻
When you change the valve block, do you have to put the vehicle up on the lifter or jack stand? Reason I ask is I read some other info that it might lose the air along the tubing and decompress the air suspensions. Thanks!
good vid! Just replaced my front air suspension spring and strut 2009 gl550 and think I'll take a look at my compressor for some reason its very loud while inflating the springs.
@@neilhale8626 I just experienced this with 2 GLs. The pump is most likely worn and they become extremely loud. I replaced both pumps, filters, and relays. Both are barely audible now.
@@neilhale8626 If it’s noisy and loud and runs for too long, something is wrong with it for sure. My ML280 had this for a long time, and then the malfunction message game up on the display eventually. Had to change it and then it was fine after.
🙄 blind leading the blind. That is indeed the air intake hose. The filter at the top is the air filter for the compressor. The “exhaust” is the actual compressed air the compressor pumps into the system . It’s no different than an air compressor used to power tools and equipment. That port also serves as a system pressure relief for when the lowering command is issued. The same port is controlled by a solenoid. Power it one way and it lets air out, power it the opposite allows the compressor to intake air for compressing. Come on guys, this is not rocket science.
...I noticed you said that the cracked and dry rotted hose was an intake for the compressor.... if you check the direction of the filter air flow on the hose it indicates an Exhaust hose , not Intake.... Check it on the filter and let me know if I am icorrect please
+Positive Person I noticed the same thing on a couple of GLs, it is definitely an intake hose for the compressor, but I do not know why the factory installs the filters backwards, if might have to do with how the filter is more efficient, or so it never uses a by-pass in the filter... That's just a guess though
You did miss it my friend! He said with the broken intake hose dust will be sucked in the compressor and will end up your distribution valve causing damage to the seal resulting in losing air pressure to air springs (struts).
Is it possible to replace just the inlet hose? I had the same issue and I cut it back and reconnected but a few months later the end dried up and crumbled again. I replaced the filter and the rest looks fine so it seems silly to spend $150 on the whole assembly when I just need the hose replaced.
@TheFilthysoap I ended up taking the hose to a local parts store and had them measure the inner diameter and I bought fuel line hose that matched. Haven't had issues since. It's just rubber hose for air really. Anything you put will eventually dry and rot over a long period of time like the factory hose.
I notice that my hose broke in the same place, likely due to being bent there by the compressor vibration. I simply cut off an inch of hose and reconnected it.
I did the same. I was pulling off the front bumper to pull the headlights out and noticed the hose broke. I cut the hose and mine had a clamp on it. Hopefully its still on.
this is very confusing. the arrow points toward the short tube, not the long tube that goes into the compressor. what gives? is the air coming out of the compressor? that doesn't make any sense. why would they filter the exiting air?
i am not sure how to explain my issue. Dealing with it over a year, compressor always fails, start pumping and never stops. on dashboard it says that compressor fail. Change already all my struts, change pump like 5 times, change air block, it always fails and pumps until the pump burns. eeeeehhhh did any one ever experience it same issues?
I have similar issue except the compressor heats up and stop never runs for ever. I know overtime this will kill the compressor totally since the compressor has to run more often that it should. I know my compressor is working because sometimes the car reach normal height. I don't think a bad air intake filter cold cause the car to drop. That said, did you fix your car's issue?
@@old_channel1 hi, yes fixed. You will not believe what was the issue. Part cost $10.00 So after spending about 5k to replace all Basically front it was giving me same issue. Then I found a guy from Mercedes, who hook it up his computer and figure that one of my relays wasn't responding correctly. After all, change relay $10 and all went back to normal
Relay sticks. If you buy a good quality compressor (Arnott or OEM) it tells you to replace the relay otherwise warranty is void. Arnott include a relay with the compressor.
Why would u replace the pump more than one time without replacing the control components for the pump if it was pumping just not shutting off? And ok, so u didn't test the original pump to see if it was bad or was it not shutting off so u figured ud just replace it? And ok either way, at least after replacing it then one would think there's no way ur next step wouldn't be to move on and start replacing the other parts in the circuit like sensors and relays that turn the pump on and off...not replace the pump a 2nd time...or 3, 4, 5 times. And replaced all ur struts/shocks, the most expensive parts first all the way around the vehicle for a pump that was just not shutting off? Like holy shit. I wouldn't recommend ever working on ur car urself again without practicing basic troubleshooting on a cheaper to repair electrictronically controlled piece of equipment of any kind or just a cheaper car maybe
100% wrong. This filter is used as a fuel filter in some cars. The only reason for the directionality is to visually be able to see if the filter is getting dirty. THATS IT. It’s NOT a one way check valve.or a diode.
adam No it does not exhaust. The exhaust is the actual compressed air the compressor “pumps” out. The port is the air intake, for compressing, and the pressure relief for lowering the vehicle.
