Ok, that is the correct procedure. To fill the bags, for most, the X has to be lifted a bit for the computer to compensate.

Now Arnott are good bags but sometimes the band collar that secures the rubber bag to the strut is clamped on incorrectly and allows air to escape. But it doesn't sound like that in your case. Now some have also complained that after a R&R with Arrnot, their system needed to be reinitialized in order for the ride hight to be correct. Let someone else chime in to see if they concur.

Most of the time this happens when someone changes 1 spring but keeps the original. After getting everything back in place, one side is higher than the other. Normally the higher side was the original bag.
