Rhythmic clicking noise from the WABCO box

Perfect! PO had replaced air with springs, so hopefully that explains it all.
I also get an intermittent sensor light (the one that looks like the tailgate is being lifted) whenever I fill the tank, hit a bump, load kids in the trunk, etc. I assume that is related too. I'll look into disconnecting the air line and update.

The best approach to addressing the fact that the air springs were replaced with coils is to change the setting in the self-leveling, antilock braking system (SLABS) computer from air to coils. That shuts down all the air springs circuitry, etc. Leaving the SLABS set for air springs can also result in a parasitic draw on the battery as the system continues to try to work even though the air spring bladders are gone.
It takes an ABS-capable scan tool to change the setting. Perhaps there's someone near you that has one, although I don't recall any other active forum members in or near Kansas City. The dealer or a Rover specialty shop would also be able to do it but would probably bill you a diagnostic charge.

Still working on this, having trouble!
I've been trying to figure this one out, but don't have access to a scanner or the ability to change the computer. Curious if there are any ways to hack it so the compressor stops trying to engage, it keeps draining the battery. My goal here is to detach the compressor in a way so the SLS light does not turn on and the beeping doesn't happen while I'm driving over 20mph.
Here is what I've tried:
Unplug the compressor - this stops the compressor from attempting to work, but it turns on the SLS alert light, and the car beeps uninterrupted when I drive over 20 mph.
While the compressor was unplugged, I also tried to unplug the ride height sensor and the fuse, still no difference to the light and the beeping.
With the compressor plugged in I unplugged the ride height sensor (thought it was fixed for a few days, I was wrong), the SLS light is still on, compressor still tries to engage.
Haven't found any other threads on this specific issue, and ideas?

Under driver seat ?
The Wabco box for anti-lock brakes under the hood does have a 'rhythmic clicking noise' I measured and all Discos show :

With no way to find explanation or data from anything Wabco.

Dlueck, you're right. I too worked through all the alternatives you describe but with no successful outcome.
