Airmatic Suspension Control Valve Block Replacement
I have a 2007 S550 W221.
I have had the Airmatic Suspension error light (Car with Arrow pointing Up) in my dash ever since I bought it. Since the car looked level and goes up and down as it should, I never bothered with it. I finally took it into my indy shop to diagnose an unrelated issue and the mechanic diagnosed this light as well. After going through some STAR computer screens, he declared that the ARIMATIC Suspension Control Valve Block (Part No. 212-320-03-58) was defective and needed to be replaced. I am now looking to DIY the replacement and have the following questions:
1. Should I access this valve from the bottom of the car, from the front right wheel well, or the front bumper? What would be the easiest approach?
2. Does the compressor needs to be removed to access this valve?
3. How critical is this part in terms of Original Mercedes vs. non-OE parts (eBay)? eBay prices range from $125 to $250 for non-OE and $350+ for Genuine Mercedes.
Thanks for all the help.

1. Should I access this valve from the bottom of the car, from the front right wheel well, or the front bumper? What would be the easiest approach?
- When I replaced mine last year I removed the right front wheel and fender liner and was able to get at all the fasteners and connections. The only thing that would have made it easier would have been to remove the bumper, but I didn't need to
2. Does the compressor needs to be removed to access this valve?
- No
3. How critical is this part in terms of Original Mercedes vs. non-OE parts (eBay)? eBay prices range from $125 to $250 for non-OE and $350+ for Genuine Mercedes.
- No experience here, I bought the Mercedes Part because I found a deal, which has since evaporated. I bought mine for $249 for the Mercedes-branded new part, it is now $350 from the same supplier.

I meant to write "I am NOW looking to DIY". My lazy fingers betray me every now and then!

Just to clarify, you stated you are not looking to DIY, assuming you meant you are looking to, yes?

I mean like raise all the wheels , how to refill the system with air, etc.?
I am trying to do mine and trying to figure it out if I just raise the front at the middle is enough and is it as simple as disconnect air hoses reconnect, reassemble everything and turn on car?
