Rear Air Suspension - what do I need to know?
I'm going to look at a 2000 D2 tomorrow and it has rear air suspension which I believe is also referred to as SLS.
I'm obviously new to the air sus, can you folks tell me how to test it and what to look for?
I assume the button on the dash will simply make the rear go up and down? Should I check for leaks, etc?
I have head you get a nice ride out of them but most articles on the web talk about replacing them with coils.
Any help is appreciated!

- is the air suspension really good? I assume it gives a nice ride, but would like to hear some feedback. Most I've seen have been converted.
- Can you lift suspension that has airbags? (I assume someone sells a lift block?)
thanks!

If it's in good working order I would keep it. Yes you can lift it with the airbags, I believe you can get slightly larger airbags plus I think Terrafirma makes a 2" lift block that works with the bags. I was going to go back to air on my green one but I got a great deal on some shocks and springs that I had not anticipated.

Note to self: When you press the dash button to raise or lower the rear SLS suspension, you need to hold it in for I believe 2 seconds. With all doors closed (will not work for example if you have the tail door open or the drivers door open). It will beep and the rear air (top right of instrument cluster) light blinks yellow as it goes up. Once it's all the way up, light remains steady yellow.
Mine takes about 13-14 seconds to fully raise. If it takes awhile (making this up but I'd say 30+ seconds) you may have a problem or a weak compressor/leak.
Then to lower the suspension, if you start driving and exceed a certain speed you'll hear beep-beep-beep and it lowers automatically. or you can again hold in the button and it'll deflate down, blinking until it's down, then the yellow warning lamp remains off.

I like the ride it provides as well. It’s way more smooth than my 04 with a medium duty EMU lift. I thought about lifting the 03 for a minute and I found blocks at Lucky 8. I’m just keeping it stock.
