If you are parked at the gate, the VDGS module is turned off. This is normal at Lanzarote Airport. The VDGS will turn on by itself if you drive up to it from outside of the gate area. If you want to check if the VDGS module is working, you can spawn your plane at another gate or the runway and taxi to a gate with a VDGS (Gate T1 to T6).
Please check you didn’t accidentally remove the folder ‘noolaero-module-VDGS’ from your community folder. If the folder is missing, please run the installer again.
It’s possible you might have overwritten the ‘Noolaero-module-vdgs’ folder with an older version of the module. Please run the installer again.
