It seems like this option would be a quick shortcut at no risk of burning anything up. (my relay WAS badly worn and seemed not to conduct when checked with a meter so I cleaned the points, got it working fine.. still no air pump activation)
Seems like a worthy experiment..(I did notice an overheated wiring smell about a week ago plus, then it cleared up and that was that)

If you're already getting to foxwell just wait till you have it in hand. It's just so easy to remove the suspension up and down and test everything out. Yes I agree you can probably Hotwire the relay and run the pump.
By the way if you're screwing around with the foxwelk with the ignition on you're probably in the garage running a suspension up and down Etc. Have the battery hooked up to a charger cuz you will run down the battery.
From what I've read you can also get a rebuild kit for the pump because the point of failure is actually the seals on little piston that goes up and down inside the compressor.
Also the E320 as far as I know is not airmatic it's just self-leveling. The difference is that you don't have the up-and-down switch next to shifter and you don't have the Adaptive shock absorbers. That's a good thing in my opinion cuz the shocks and airbags are hell of a lot cheaper than airmatic shock absorbers like on the E500 wagon.
Originally I really wanted an E500 wagon but the mandatory 4matic and airmatic kind of scared me away. I'll live with less power for the sake of simplicity.
BTW if you don't have this already, you might find this service manual useful.

Donation pop up is annoying but dig into it. I found a lot of useful info here.
