What are these and where do they go?!?! Please and thank you.

 

To your air/dynamic shocks that have been removed, from the look of things.

 

+1 Airshocks have been removed and replaced with coil overs.
This is what air suspension looks like from same vintage point:

 

They don't go anywhere any more. The failed air suspension system has been replaced with steel coils, which is a Goode Thing.

 

Awesome, understood. Thank you very much

 

Wrap them with isolator and leave like it is , just to keep the possibilety to mount airsuspension struts again later on yourself or someone else.
air compressor is at the front left side behind bumper , 4mm nylon hose going from there to the boot from below car into Valvebody at tank inside boot below the sparewheel and styrofoam protection. And from Valvebody with 6mm nylon hoses to front struts and 4 mm hoses to rear struts.
then there is a Wabco Airsuspension module behind the rear back seat .
Total weight probably 12 kg so just not worth the effort .
Airstruts are lighter than coilovers
