@LIVIU1995 Is the new compressor working? Did you delete all DTCs after installing the new parts, and did they all disapear? As long as you just changed the compressor, there shouldn't be any calibration needed. If you didn't damage the leveling sensors, you should simply start the car, enable air suspension and drive a little bit.
If Vdash doesn't show advanced options for specific ECUs, those functions are either not implemented jet, or your account isn't unlocked to access them. "sponsored" accounts for example, don't have full access to all functions. You could also try a mobile phone app called V-Tool https://v-tool.app/ in combination with a vLinker MC+adapter. This app is similar to Vdash in terms of diagnostics and service functions, but seems to support more functions on some cars.
