Any news? Btw I am installing arnotts on the front tomorrow. Now will have arnotts all around. Anyone know if I need to hookup star after? Or recalibrate the ride height? Or what do I ask them to to with star.

I went to my indy over the weekend - no codes but the suspension still drops randomly to about 23.5" (from 25.5") when I unlock the key. I think it may be a self-leveling issue. I had him raise the front struts to 26.5" so that when it settles down over a long period of time, it won't go down to 24". I'll have to track and see if this does anything for the rear.
You should definitely have your indy recalibrate after installing the new fronts.

agreed...the car itself doesn't care much about the strut. the sensor determines if the car is level along with other body sensors and airmatic computer adjusts accordingly.
i'd recommend further diagnosis with latest STAR system if you haven't already done so. for example, one of my body acceleration sensors was faulty and my ELM did not work with no dash codes. i figured the ELM was junk. 1.5 years later my buddy does some work on my car and decides to use his new scanner to scan for all codes. found a bunch of past airmatic codes which he cleared. soon after i received a brief visit workshop dash item that went away. Had my buddy scan once again and only one fault appeared, for a body acceleration sensor. i replaced the sensor, and suddenly my ELM was working like a charm. mind you...factory lowering and suspension function was working this entire time.

My indy checked for all codes and found nothing. We're all at a loss.
After checking on the car about 10 times these past two weeks by simply unlocking the car without starting the engine, the rear dropped 3 times in those. It seems to be random when it wants to drop.
Twice I would unlock the car (but not start engine) and there would be air releasing. Before the rear sinks all the way down, I start the engine and hit the raise car button but that only seems to raise the front and the rear continues to sink. After shutting and restarting the car multiple times, the rear would still not raise. Sometimes though, restarting the engine multiple times does raise the rear. Other times after a few hours or waiting until the next day, I'd would start the engine and it would raise the rear back up.
Another time, I would finish driving for about 40 mins and shut the engine, I hear the air release and the rear goes down. Wait about 20 mins, started the engine and the rear raises back up.
It seems to not know when to self-level and when it does self-level, it doesn't self-level correctly. It seems to always want to drop the rear. And it does this randomly. Other times I can unlock the car, start engine and drive it no problem. No leaks or anything, car would stay up for weeks.
I really believe it's an electronic issue, just not sure which yet.
