Excellent job, this really helped me save $$$ in labor cost

[@FaizAlshehri]

Nicely done! Excellent guide. To the point. Full of useful tips. Thank you.

[@taharishsynergy8870]

Thank you for this video is really help me on my Job

[@saintjohn316TV]

Would love to see how you got it out of that tight space.

[@tedlu008]

my 2007 GL450 with 110k miles is now on the 3rd set of front air bags and 2nd set of rear air bags. But still with original compressor and valve block. Seems not too bad in comparison.

[@kaibintech]

Nice video!

[@danaolson2871]

Change the air pump inlet filter and hose. If the valve block failed it can be due to dirt getting in there. Eventually the hose gets brittle and breaks off letting dirt in the compressor and valve block.

[@erincrawford4157]

Replaced my valve block and now I hear a clicking and the ride height never changes. And today the malfunction error appeared on the dash. Any advice?

[@user-jd4kp3lp9r]

Hi I am changing mine on 2010gl350.does it require calibration after it's done.i am getting one from Mercedes

[@batukilinch7754]

I have 2009 GL 450, rears shocks are locked on at a height. I am sure why. I changed rear shocks from Arnott last year. I’m not sure why I get malfunction message on dash.

[@uknowsj8686]

Link to where you purchased the new Control Valve? My 2014 GL450 just got the lift malfunction and there is a noticeable difference between the front and rear ride height. Great video!

[@Zionntrain]

This happened to my 2014 as well just last night, kmt I'm pissed! Looking for a buyer

[@bhirmiz]

My 2014 gl350 intermittently sags the rear when off. But when you enter the vehicle it raises up with out touching the ignition???? Anyone help.

[@johnq5307]

Hey Chip, another question; you said your GL is a 2015. Why didn’t you bring it in under warranty?

[@Chip6565]

It was bought at auction with 1k miles involved in a crash. MB voided the warranty as it was considered a total loss with 4K damage.. go figure.

[@johnq5307]

Chip6565 wow! What did you get it for?

[@khaledibnwaled]

Any link online for pumps please!?

[@firetaz39]

Chip6565- Did this valve block replacement completely resolve your issue and still holding? Did you say in beginning of video that front and rear were unequal front to rear? What about left and right? I have front pair much higher than rear that are sagging equally low... What diagnostic software did you use to tweak ride height later during airbag replacement?

[@Chip6565]

Since this video I have replaced the valve block a couple of times. It is a mechanical part that is prone to failure in my case.. I have also replaced a leaking airbag in the rear. That caused it to sag in the corner. Neither repair requires software to replace.

[@cooperdarly7738]

Did you replace the compressor filter?

[@mgolfgreat]

Great video and investigation, on my GL450 2011- I changed the valve body block, repaired the cracked compressor intake hose, replaced the intake filter, replaced the 40 amp fuse, replaced last year both front air springs but I still have the level malfunction? can you give me advice on whats going on, I dont want to pay the dealer $179 for diagnoses. I will check back later for your response

[@Chip6565]

You haven’t really explained what the problem is.

[@michealbrown1478]

Hi Al Abbasi, Did you manage fix yours? Mine Ml 350 is doing same thing. One side is higher then other and also have malfunction message coming on dash. Can you please tell me what was cause on yours. Thanks

[@Convex757]

How did you fix the first issue?

[@Convex757]

Did you get any codes

[@1stCme]

Hello. Hope you can help. I have the same exact vehicle. The malfunction symbol came up and on the rear passenger it’s low and my rear tires are wearing out in a matter of 3-4 weeks. Do you think because of the rear end being low is causing the tires 🛞 to be wearing fast?? Looking forward to your answer

[@Chip6565]

I’ve replaced my airmatic control valve three times now. It is likely the problem. I always keep one on the shelve and with me when I travel!

[@1stCme]

@@Chip6565 thanks a lot for the quick response. I appreciate it

[@22JSaucedo]

How did you calibrate the suspension system after you replaced the part

[@Chip6565]

I don’t believe that is necessary although I do have diagonostic software and do recall recalibrating while trying to troubleshoot a leaking airbag that I replaced several months later.. in either case I don’t believe it is necessary. Their are separate sensors at each wheel that control wheel height and that is a separate system.

[@stephenmichael3395]

I am glad you were safe.. This suspension is complete and total garbage..you will continue to have nothing but problems with this.. I am sorry to say..

[@zachariasvan3965]

You ain't know shit.

[@nlroel]

My 2013 GL 63 got the same malfuction on front right suspension. Suspension is on the lowest level. The other 3 air bags are ok. Is it also the valve block or a complete strut? I hear the air

[@Chip6565]

My valve block has failed a few times. It’s hard to say what has happened to your GL63 without looking at it. Good luck

[@nlroel]

@@Chip6565 i took some soap and spray it on the front strut because I hear hissing from that part in stead of the valve block…. And I see some bubbles😊. Pff will cost a minimum of 1800 each. So OE Mercedes or Arnott….

[@kaibintech]

cool

[@johnq5307]

Hey Chip, Did your suspension drop or remain the same? We’re you able to raise and lower with the switch in the middle console? Did you run diagnostics with diagnostic tool? My malfunction light came on yet everything still seems to be working fine. I purchased an icarsoft scan tool and it looks like I lost comm with the airmatics. Thanks!

[@Chip6565]

The suspension did not drop when I had the malfunction. I don’t recall trying the switch on the console.i had access to the Star Diagonostic tool but it wasn’t needed.

[@Chip6565]

I don’t know what you mean by stating lost communication with the airmatics. Nor what problem your experiencing. I’m no expert but have been successful fixing it myself a few times now.. twice I have replaced the left rear airbag which leaked. The first was a knockoff brand and didn’t last long. And have replaced the distribution block. No communication issues.

[@johnq5307]

Chip6565 Thanks for the reply. I’m having a similar problem and it seems to have corrected itself. The code i was getting from the scan tool was comm loss between the instrument cluster and esp. we’ll see if it comes back.

[@johnq5307]

Chip6565 the comm loss diagnostic read with the icarsoft tool is between the instrument cluster and esp module. I’m thinking (hoping) its the issue you experienced and because the message didn’t match the expected result, cured the error.

[@clabruno]

I have replaced compressor, valve block, all 4 airbags and I am still getting a leak somewhere? When I raise the car it causes my compressor over work and then give me error code of compressor cooling down. When I lower the car the front end is much lower than the back and Undrivable .. any idea?

[@Chip6565]

sounds like there is a leak in the system somewhere. most likely in the front if it’s dropping. I’d spray some soapy water around the fittings and airbags and look for bubbles once the system is charged up with air.

[@clabruno]

@@Chip6565 when raised the car stays up though. Only when I try to lower it does the front end drop to the ground. The rear part never lowers

[@Chip6565]

Perhaps the valve block is defective. It has selonoid valves and are common to fob as. I have a 2015 Gl and have gone thru two in 70k miles. Having a spare is a good idea!

[@clabruno]

@@Chip6565 valve block is 2 days old…

[@Chip6565]

Well if the original valve block did the same thing you have to look elsewhere. Not much to the system: four airbags, pipes and a compressor.. see if you can find a leak with soapy water when you have the front dropping.. good luck

[@YouTube.TOM.A]

If possible carry the vehicle to a shop and have them reset your shock height values. A lot of us with Mercedes are riding around with incorrect values on all four Air struts

[@mikimiki195]

Unnecessary values are already saved in brain of the car. Values do not change just because you had issue with suspension. 👍🏻

[@YouTube.TOM.A]

@@mikimiki195 Incorrect values do not change because of suspension problems but the correct values on all shocks gives proper articulation of the suspension components through all operational variables, ride height and stiffness selections.

[@mikimiki195]

@@KZbin.TOM.A I do know values do not change I’m saying no need to do anything with values when replacing bags. Values are stored in computer and don’t need to be changed unless desired. 👍🏻

[@YouTube.TOM.A]

@@mikimiki195 Thank you, if i have a scanner that can reset those values i do that, [ resetting back to factory setting ] I don't believe any innovation I can create would be better than the factory values, I like keeping the factory camber.

[@mikimiki195]

@@KZbin.TOM.A i do have MB Xentry and recently purchased TopDon

[@tedlu008]

Wonder if it’s still within warranty?

[@Chip6565]

Unfortunately it is not

[@ubuntungabantu6730]

Where is the relay and fuse for air ride suspension in the fuse box?

[@Chip6565]

check the fuse box under the rear seat. there is a fuse diagram there to locate the location of the various fuse boxes and related components.

[@Chip6565]

I purchased a generic Chinese part on eBay. They’re all made in China so why pay OEM price for exactly the same thing.. search Valve Block Air Suspension Mercedes Benz GL450 550 2123200358. Your part number on the original is likely the same. Just confirm the year and fitment with the seller if you have any doubt. I think this part is widely used for multiple vehicles. At the time they were about $75. Quality is the same as far as I can tell. Looks exactly the same as OEM without the part number. And LOTS less expensive.

[@aldinoaldinovic6282]

nope... you buying Chinese knock off. i did similar mistake in feature ending buy OEM because Chinese crap didnt work for long or correctly. Original MB part is Made in Germany.

[@PeterFlores323]

What do the colors mean???

[@Chip6565]

Colors are used to identify where the lines are routed from: airbags, tank or compressor. The block also has colors and codes like RR for right rear, etc.

[@maxagent86]

This was not a correct installation. There is a reason for the ferrules that were on each of the air lines. They prevent the line from coming off of the threaded fitting, which can happen under pressure. The ferrules have to be transferred from the old valve block to the new one, or new ferrules need be installed. Either way, this can only be done with the removal of the fitting, not by just pushing in the line, as done in the video. I recommend that you re-do this step in order to prevent a possible mishap. Viewers beware.

[@RENIELTUBE]

Stop talking about things you are not sure about :-) The ferrules ARE already in the connectors from factory.. And yes, it IS a simple push in and pull back gentle to seat the hoses correctly.. However the video is a little misguiding as you should NOT tighten the brass on the new valveblock at all.

[@stanjones8495]

@@RENIELTUBE about to do this repair and just want to be sure about the lines. Simply push them in and the ferrules keep them in place? I did the compressor and I concur about tightening, it specifically said not to tighten but I messed up the air line, local shop corrected it for me, said you need a special tool.

[@RENIELTUBE]

@@stanjones8495 You can do it yourself in the following way.. unscrew the compressionfitting,(even though the instructions says not to) pull off the white/black plastic plug (while taking care not to loose the fitting or the ferrule). Cut 5mm of the old hose with a stanley knife (the old ferrule will have mangled the hose a bit) Push fitting approx 10mm onto hose . Push ferrule approx 2mm onto hose (cone towards fitting). Push hose and ferrule into receiving hole until bottoming out (further pushing the ferrule onto the hose until the correct distance is reached) remove hose from hole and lightly pull fitting towards ferrule (without mowing the ferrule). Push hose and fitting in hole until bottoming out, lightly screw in fitting until seated and o ring is tight. lightly pull hose to check if compression ring fitting has bitten..
