Sounds like an installation issue.... did they follow the procedure correctly during install? Vehicle’s weight needs to be supported with fully depressurized system after installing new bags and connection instruction from arnotts (do not unscrew new fasteners from new bag to reuse old connectors) must be followed to prevent leaky hose lines.

I have driven on fully deflated bags to get home to my scan tool but I wouldn’t recommend it for longevity of new bags and compressor if you are able to troubleshoot it your self at home.

Edit: I’d drive it back but don’t tell the shop it happened last night - tell them it happened on the way there (to prevent any “you shouldnt have driven it” claims for warranty)
