XC90 – Completely deflate and refill air suspension with OrBit?

[BOSS89]

Hi everyone,

I have a 2017 Volvo XC90 with air suspension and I need to replace the air suspension compressor.

Before replacing the compressor, I would like to completely deflate the air suspension system, including both air reservoirs and all four air struts.

After installing the new compressor, I need to refill the system with an external nitrogen supply and would like to do the following:

Completely deflate both reservoirs and all four air struts.
Connect the external nitrogen supply.
Fill the air struts individually.
Fill the reservoirs afterwards.
Perform the air suspension calibration.

Volvo VIDA has a diagnostic procedure for deflating and filling the air springs and reservoir, but I would like to know whether the complete procedure can also be performed with OrBit.

I saw that newer OrBit versions mention an “Air Suspension Fill/Deflate” function, but I cannot find it or figure out how to access it.

Can anyone tell me where this function is located and whether OrBit allows me to individually control/deflate/fill all four air struts and both reservoirs?
If possible, I would really appreciate a short step-by-step explanation.

Thanks a lot!
