Im looking for ISTA or INPA Software. Need some advise.

Which of these solutions would you recommend for diagnosing and resolving an air suspension issue on a 2006 4.8is with dual axle air? I have a Foxwell NT510 Elite and I have been able to raise and lower the suspension despite the "Suspension Inactive" message. The suspension is now non responsive, even the lights on the indicator for the driver are off. I checked the fuses and all seem fine. NT510 reads as no error codes for the suspension, the inactive message still appears.

I can test the compressor and it is holding at 12.2 bar. When I call for raising the axle or one corner at a tie, the compressor turns on for a moment then shuts down. Suspension is currently down all the way so I'm avoiding driving at all.

Someone mentioned "Line mode" earlier - what is that and how can I adjust? Could I have set it in error?

PS I have PA SOFT BMW Scanner that seems to read the codes but I haven't figured out how to get the suspension to react.

Thanks in advance.



UPDATE:
Still interested in a more powerful diagnostic and maintenance solution but I was able to "reactivate" the air supension.

Using the Foxwell NT510, I entered the Suspension module under Special functions. It allowed me to enter the current measurements in mm for each corner of the car. They were all out of spec. Once finished the compressor kicked on and raised the car properly at all 4 corners. There was a message that the Assembly Line function was now disabled. I still have the suspension inactive message but the green indicator lights are back on and the car is drivable once again. May have to tweak the final ride height but back in the game.

Any recommendations on how to properly diagnose the system appreciated - at this point since the system is holding air I'm guessing the control module.
