Outstanding! Great diagnostic approach. Possibly too time consuming for the repair shop, but great for the confident and creative DIY. I really appreciate the break-down of the pin connections and valve operation. I am surprised that the pin 1-3 combination opens both valves. I would have expected one pin to each solenoid and a common ground on pin 2. I really like the approach to test each air spring. Oddly, it did not occur to me until I saw this video that they could be tested without removal. It would be interesting to see what the valve block looks like inside.
complimenti! professionale illustrazione. Una domanda..Il difetto che riscontro e' che il mio w212 si abbassa il posteriore sotto gli 8/10 gradi e di conseguenza sento spesso il compressore che carica durante la marcia; mentre oltre i 15 gradi l'auto resta "alzata" oltre 48ore. Possiamo associarlo agli air spring? Grazie per l'aiuto :)
ciao se il sistema garantisce adeguata tenuta dell' aria in pressione l' auto non dovrebbe presentare un abbassamento significativo nel corso di piu' giorni.. se dopo appena 48 ore si nota un abassamento di livello e' plausibile credere vi sia una perdita.. da verificare tenuta soffietti, tubazioni e raccordi..il fatto poi la perdita sia piu' pronunciata con temperature rigide farebbe pensare sia legata a qualche tenuta in gomma che indurendosi perde ulteriormente la flessibilita' dei materiali necessaria per garantire tenuta..
My main airline to the compressor keeps popping out when I try to do a level calibration. I just replaced the level sensors . I was wondering if I need to buy a new fitting for the back of the compressor
Thanks for the video. I have a W212 but mine is sedan with four bags. During cold days the car looses air at night and in the morning is flat. It takes a while to go up of course. I have replaced the main valve but it still does the same. The only mode where it doesn't loose air is when I leave the car in high, like for snow. If I don't loose air on that mode I know the bags are ok but in any other mode, comfort of sport, I loose air. Any thoughts?
Probably means you need new air springs. The Arnott ones aren't incredibly expensive ($200/ea), although full Airmatic on all four wheels may be different (I have a wagon with just rear self-leveling).
plastic rigid tube (Rilsan) external diameter is 4mm and 8mm... go to the home dipo and ask for air fast fitting for Rilsan tube as the diameters above.. gauges and other hardware is 1/8...
@@diycarmechanic587 Great video but I am having the same problem in locating the parts to do this. I do not want to take the connectors off the tubing so knowing what the threads are would help a lot in getting a couplers etc that I can screw the tubes into. The tubes on my E250 2012 are OD 4.2mm and 6.3mm.
black plastic circular piece with eletric connector on the opposite of cylinder in the compressor.. open it and check for internal corrosion..is a solenoid valvle so you can use a tester for checking continuity and a 12 volt source for testing proper functioning..
Hi my w212 wagon e250cdi 2011 open air matic not.every time somtime 1 week somtime 4 day sommetime when i drive writing failure i didnt understand what si real problem plz tzl me man .thank from istanbul

Perfect video I’m have the same issues
2010 E550 bags grate video
very interesting, especially with the answers below, thank you
Love your technical videos, keep making them!
thanks for your support end compliments for your channel..bye
Thanks for the video, very interesting!
A question: where did you jack up the car in the middle back? Is it on the differential? T
well done presentation 👍
very god explaining!

change all VOSS brass fittings with new ones...
Good video! I have problems with that same part. Do you know the reference?

@@BruceLudwick thanks Bruce
@@BruceLudwick in fact, they are more expensive. Each front is about 600 and the rear ones about 400. I have to shell a good 2k to fix it.
Hi again. What are the thread to fitments as I want to get the same setup as you to test my system please. Thanks very much

Haben Sie airmatic dc?

Hi where is the relief valve located please
black plastic circular piece with eletric connector on the opposite of cylinder in the compressor.. open it and check for internal corrosion..is a solenoid valvle so you can use a tester for checking continuity and a 12 volt source for testing proper functioning..
also be sure eletrical cable is in good order without damage due to scrabbing against metal brackets....
