Figured I should start a thread about my current project. I'm going to retrofit the air suspension in my 2015 ExecLine R-Line. I will document as much of the retrofit as I can here. I'll try to includes as many pics as possible, as well as part numbers and wiring diagrams. I currently have everything except the air strut assemblies (on order), the body acceleration sensors (on order) and the load sill lower switch/trunk trim.
The latest Cayenne (958 ) comes with the air suspension in North America, so that makes it easy to get everything required except for the two dash switches. I thought about purchasing a wrecked Cayenne, but the cheapest I could find was around $9000 CAD. I acquired everything for under $3000 CAD.
I'm no stranger to turning a wrench. I'm a heavy duty mechanic, have owned over 30 Volkswagens and Audis, and have done some pretty neat swaps (16v G60 swap in my '81 Rabbit S, 1.8T K04 syncro swap in my '92 Passat wagon, VR6 swap in an '84 GTI, several MK2 1.8T swaps, etc). Overall it's not a terribly involved retrofit per se. You need:
compressor assembly and air lines
air tank
air trut assemblies
computer module
dash switches (2 of them)
FR and RR height sensors
body acceleration sensors (2 of them)
random mounting hardware (brackets, bolts, nuts, grommets, etc)
Load sill switch and right trunk trim panel (allows you to lower just the rear axle for ease of loading/unloading things)
lots of wires
Pictured below is the air compressor assembly complete with air lines and grommets, air tank, levelling module, and some pigtail harnesses.

I'll post more pics later when all the parts have arrived. I hope to start the install within the next three weeks.
I'm also retrofitting a Webasto parking heater as well, just waiting on a few last pieces to arrive. I'll create a separate thread for that, of course. Also planning on retrofitting a complete 4Xmotion system too (transfer case, rear diff).
