Anyone know?
Even better: any illustrations of the system available?

I'm having the issue of no 'lift' light on in the dash, and lift won't go down. Hoping for the sensors as pump is way to expensive a fix. Hence would like to know placement and figure how to get to all parts of the system to check out.

Thanks!

Second, would love to know this as well.

I recently had the same issue and it turned out to be one of the pump membranes not holding pressure. The pump assembly is replaced as a single piece and it costs about $9800 with an invoice price of about $7000.

When I was looking for mine, a shop in Los Angeles had a slightly used one for $2500 if you need to replace it. Really sucked.

This is all the parts, except for the dampers themselves. pump is located in the center tunnel area just behind steering rack.

14,15, 21 are pressure switches. the individual parts numbers should be available as replacements.

there is a computer somewhere too, a couple relays, and the switch. that's about it.

i believe this works based on pressure, not location, possible replacing a switch might do it.

Thanks!
Im not going to throw 7000$ after it, but would like to check if I can do anything myself.
Is it hard to get to after removing plastic covers?

First, I'm going to reset ECUs by disconnecting battery. Having not done this in this car before, will any settings be reset (PCM and so) by this?

Has to be fixable - does this unit exist on any other car? Ideally VW or Audi? Often you can find the sister part and way cheaper prices and also find individual components

Shops theory is fact the coolant pipes run right next to it the heat messes these things up.
Probably fixable pull codes and see what it is. If switches can be fixed.
Access is easy but hard if on your back on jack stands. Lift makes it way easier.
Unless you need it pull it.
