IMPORTANT: Risk of damage!
Extreme cleanliness must be ensured in the connection area of the vent lines during removal and installation. Even the smallest of dirt particles can cause leakage in the air spring system.

Disconnect quick-connect couplings (1, 3).

Seal connections of air supply unit supply line and upper vent line with sealing plugs.

Unclip lower vent line (2) and feed out.
