I had some issues with my air suspension whereas the front dropped drastically.




The mechanic told me this was the air compressor.
Prior to the change the display would always come up vehicle rising but would not rise.

I have had the compressor change but is doing exactly as it was before. It did rise on one or two occasions but not after that, it is back to square one now.

What could this be?

Thanks people

The first thing that you need appears to be a good mechanic who has access to DAS. Guessing which part to replace is a really expensive way to maintain your W220.

You probably either have an air leak in the system, where the obvious approach is to find the leak and fix it, or you have a control problem, which is less likely. DAS will tell you what the problem is in either case...

You could always pour some water and soap on both of the top of your front suspension and press the "rise" button and see if there's any bubbles, that way you'll know that it's not the compressor but a leak from the C-RING on one or both of your front suspensions.

Replaced the compressor and all is fine however the affront still sits lower. Definitely no leaks. I'm going to open a thread if you can.calibrate height settings

Since you have several threads asking for help, it would help us a lot if you would add your location and model year to your user info. Several yearly differences, several world-wide market differences...
