I have a 2005 LR3 with 175,000 miles and all is working well. I might add that I spend about $6,000 a year in maintenance so I suppose that should not be a surprise. You did right in getting your 3 towed as replacing Jaguar engines in not quite the same as installing a junkyard 350 into a Chev.
The attached link below is to my album within which are three sections related to the air suspension. I might suggest you spend a week or so reviewing and printing out the wiring drawings etc. Once you understand the air system, resolving the problem will just be a matter of time.
In the meantime you might refer to the section regarding fuse F35P located in the fusebox behind the passenger side lower glovebox; also F26E, in the engine compartment fuse box. Removal of either of the fuses, (F26E is the easiest), will at least keep your 3 from dropping while you research the problem and the solution.
Incidentally, in the tradition of "throw parts at the problem", the first thing to do is replace the brake switch. I say that as while it is probably not the fix for this problem or more likely, problems, you have to eliminate the obvious sources of problems prior to even attempting to fix the real concern.
The other cheap first attempt is to purchase four factory tail light/brake light bulbs, (P21/5), from your LR dealer, (or from a Mercedes or Audi dealer), and replace all four bulbs behind the red rear lenses.
Also it is rare that any display trouble code actually indicates the problem. The odds are you have a corroded wire in the air system front suspension cables. There are no codes for that so what you see for codes, (or not), is just an addled computer attempting to provide an answer for which there is no software code in its listing.
If you have the 4x4 display page on your NAV, (which you allude to), that can provide a hint as to if a wheel sensor is getting information or not, or "bouncy" intermittent information as would be characteristic of defective wheel suspension wiring.
One of the files in the album below contains the Land Rover Technical Service Bulletin where they allude to the suspension cable corrosion problem. I use the word "allude", as in the tradition of "never say you are sorry" or that a design is less than perfect, the TSBs tend to be a bit vague as to the problem; the solution is spend money and buy parts, in this case foot long replacement wiring harness section - of which I have a couple installed.
