RE: You know that's not the answer he is looking for...... HAHAHA....
Had he read and followed the advice of many who put that information together, he would use the search or advanced search function to find threads and posts that mentioned the #1 failure mode of the WABCO Electronically Controlled Air Suspension (ECAS) compressor which, as you mentioned that I have pointed out in several threads; one or both magnets separate from the interior of the motor shell and can be reattached using JB Weld.

DUB2DY4,
You either have a leak causing the compressor to run extended periods of time, which in turn is burning out said compressor, or you may have what was wrong on one of my A8L's, I drove it up to NJ from South Miami with the same lights and actions you state, I had no leaks of any kind, it was just a worn out compressor motor, it would run at a much lower rate of speed as compared to the others, it would also run shaky, like on/off very quickly, I purchased a used unit off EBay for $120.00 and all was right, after that I read on here by Mr. Bally or Misha, can not remember which, but he stated that the magnets inside the compressor motor would fall off, and the he re affixed them by using J-B Weld, so I disassembled my old one and that was the case, besides all the debris in there also, I used some J-B Weld and now I have a nice spare, and no it's not for sale LOL.
As far as the relay, that is not your problem right now as you state the compressor is running, you should however replace it when and if you replace the compressor, as the relay has been working overtime and heating up, and you would not want it to get stuck on after you replace or repair the compressor.
Here are some on EBay

Hi guys I have a 06 a8 with 140k was driving fine for 3 months in the last few day I've noticed the front is on the floor every morning. After I start it it's go up and it's fine today it decided it doesn't want to go up so I've been reading all ur posts and changed the relay and it works again but can't find no leaks in the air bags what else can it be ? Any one

Unfortunately it can't be anything else. At least I've never heard first hand that it was.
Try engaging Jacking Mode from the Car Menu and lift one front side at the time. If you hear air venting it is that strut for sure. Also check which side is going down first. It is not likely that both struts are busted at the same time. Buy refurbished strut.

To directly answer your questions:
Possible? Yes.
Y is it not going up? The sensor could be bad. That's why. Is it bad? I don't know. A wire going to it could be broken. The linkage between the sensor and the body/frame could be broken/missing. As the sticky says, you need vcds interface and software to test. Use standard troubleshooting techniques to visibly look for broken parts and wires. As far as which sensor, there are four. Vcds scan would tell you which one if a sensor is the problem.
