Front Air Shocks Hyper Extension Help

Front Air Shocks Hyper Extension Help
It happened two days ago while my wife driving. Front air shocks "only" raised the the maximum height. Distance from tire the wheel fender is around 4 inches. Suspension fault light came on. The hyper-extension front shocks did not leveled to normal level after parked overnight. Rear shocks were at normal height.
I used Icarsoft reader and code C2302 leveling plausible error.
Live stream shown "Firm error"???
I relieved the air from the front shocks and started the car. Air compressor came on and raised the front as normal. However, the compressor kept running and hyper extended the front shocks again. I appeared that the compressor did not sensed the front shock height and kept running. There are no leaks from shocks since the shocked stayed extended.
C2303 reservoir plausible error came on since compressor kept inflating the front shocks (passed 25 to 30 seconds) even the car was higher than normal height. Compressor error reset itself each time I turned off engine; and turn on again and kept inflating the front shocks when I started car.
I rebuilt air compressor with new ring a week ago. One front shock was replaced with a good condition three days before hyperextended shock occurred. My wife drove the Jaguar for three days straight after one of the front shock was replaced with no issue with compressor or shocks.
I Google searched as well search in this forum and cannot find anyone else had the similar issue.

Sounds like the front height sensor is not registering with the ASM. It may be stuck at zero or some low height value, the car thinks it's too low and tries to raise it up (hence the compressor running). It isn't seeing the change expected at the front height sensor and keeps adding air.
Sounds like you have SDD or similar, what is the data for the front height sensor indicating? If you remove the link to the sensor and move it manually, does the data point respond?

I found the problem. One front right height sensor came loose. I probably weaken the end link of the height sensor earlier when I extended the lower arm to change out the front shock. Lesson learned, remove height sensor before remove and install shock. The end link metal rod is weakly adhere to the metal rod and can easily be damaged.
My one question. Do I order new sensor or just reconnect end link steel rod to rubber end? For now, I actually cleaned the steel rod and rubber end with acetone, applied a thick heavy layer of silicon.
I will replace it if Guru here advices me to get replacement sensor.

Try a repair, should be ok.
