Hi, I have a 2013 E550 with 60k km and I've noticed that the right side sits about 5cm lower than the left side, both the front and back do this. When driving it's not as bad maybe 2cm lower on the right side. I checked for leaks and didn't find any and when the car sits for days at a time the suspension does not sag, it just stays 5cm lower. Should I be concerned about this?

Thanks

 

This small sag is only the beginning of what's next.

Start maintaining your air suspension system is not a bad idea. Let your wallet have the final say

 

Beginning of what exactly? It doesn't seem to be sagging, it's more like the computer has it sitting lower for some reason. Finally what maintenance should I be doing to airmatic?

 

Compressed air involves compressed H2O. Loosing the trapped water is half the battle in freezing locales.

When the air circuit is sealed there is no new additional moisture being introduced and accumulating. So it boils down to: you don't want to ignore leaks to prevent rusting carbon steel valves.

The usual suspects include compressor, valves, lines, sensors and bags.

There are many mbworld specialists who know every bits of this system maintenance - I don't

 

If one side is effected both front and rear, it could also be the level sensor.
You will need a mid range scanner or better a Xentry to troubleshoot properly.

I don't know if iCarsoft MB v3.0 can read airmatic or not. This is the lowest cost MB ready scanner but no true bidirectional capability I think.

Being a 2013 model year, now near 9 years up is where $$ starts to flow out of your wallet when you own airmatic. It is given, super comfort has a price to pay. Even our regular dampers will go kapoot.
Rubber spring will tear or leak, system will have some rust from wet compressed air and etc etc.
It is part of wear and tear.

 

Nah is either one, or the other. Valve block, or bag. I am already gathering parts to convert to standard suspension with coding. And for the love of god if you get them replaced (bags) do not go with MB ones. Even though they are using parts by Continental (same as Arnott's), they fail really fast. At least with Arnott's you get a lifetime warranty.

 

Yes, you should be concerned about two-inch level difference between sides. Even the 20 mm, i.e. 3/4" difference is big.

 

You call 2" sag small?
