That way at least your suspension would not run when you put a load in the car, or under heavy braking. You might be able to scribe sensor arm position, remove sensor, then JB weld the sensor in the right position, pin, bolt, whatever works, then reinstall sensor in stock location without arm hooked to control arm."
So, for the slow kids in the back of the class room, what you are saying is keep the sensors in the stock location but relocate the sensor brackets (how they are attached) so it does not move w/the control arm?

I can't imagine that those sensors are anything but potentiometers, i.e. rotary variable resistors (like those found behind volume control knobs).
By determining the resistance at a specific point, you can wire up a resistor, and put that where the sensor used to be. It's not rocket surgery - just put a multimeter on the arm when it's loaded at the point you want, and then put a little "deadbug", potted resistor pack on that circuit as appopriate. Bonus points if you can find the right connector so you don't end up splicing or hacking into the stock wiring.
Seriously - sensor deletion is easy, especially when it's probably just an Ohmage measurement you're looking for.
By the way, I'm not sure what the end goal is here (unfamiliar with the parent topic).
Just an idea,
real goal to basically turn off the suspension. That is why I have not done this nor "locked" the sensors to date. These are tricks to make the suspension think it is at the right level regardless of condition. I would prefer to be able to have the car forget that it ever had a pneumatic suspension. This would allow me to completely remove all the air components.
Since I have not been able to figure out what I want to do I might have to revisit this as an alternative.
Then figure out a way to hold them so they don't vibrate out of the "right" spot so that the car thinks the suspension is at teh "right" height all the time.

coilovers, or even the idea of doing coilovers in the near future. I know there has to be a way to get rid of extra suspension components, and have the car work correctly, we just need to get the right person working on it, or stumbling into the conversation.

As I come up w/ideas (I'll have an engineer friend or two under my allroad next week) , I will bounce them off the list to come up w/the best solution.
Honestly I only have a problem when I load the rear of the car and even then the only problem is the susp warning light which doesn't do anything except negate the ability to disengage ESP. And when I am hauling crap I am usually not hauling ass so it doesn't really matter too much.
I've wondered about an A6 ECU, about sending false speed signals to the suspension, about installing little bladders in the coils as helper springs (not really serious of course) and etc. etc.

hooking speed signal for headlights, and suspension to spare sensor. I unhooked speed signal to headlight controller under rear left panel, and unhooked speed signal to suspension controller at right kick panel, but the suspension still dropped from level 4 at 20mph which means there was another wire somewhere sending a signal for speed to suspension controller. I gave up at that point for lack of not wanting to rip more of my allroad apart.
I was trying to make manual mode true manual mode on my 01.
I guess the whole point of this post is that I have a spare speed signal sensor if someone wanted to play with it. : )
