The <strong>air</strong> springs<br />
The front <strong>air</strong> spring is a new design.<br />
As on the rear axle, the <strong>air</strong> springs are combined<br />
coaxially with the dampers as a <strong>suspension</strong> strut.<br />
The rear <strong>air</strong> springs are identical in design and<br />
function to those of the Audi A6 with self-<strong>level</strong>ling.<br />
Design<br />
While in the case of the rear <strong>suspension</strong> strut, the<br />
connection/seal from the <strong>air</strong> spring (piston) to the<br />
damper is made via a double-seal bayonet<br />
connection, on the front <strong>suspension</strong> strut it takes the<br />
form of a single-seal N17 connector.<br />
The differences in design require a different<br />
assembly.<br />
Front <strong>suspension</strong> strut<br />
The assembly of the front <strong>air</strong> spring with the damper<br />
is carried out without lubrication. The N17 connector<br />
and the O ring must be absolutely dry and free from<br />
grease.<br />
Before assembly of the <strong>air</strong> spring, the O-ring<br />
is placed onto the second shoulder of the damper,<br />
ensuring an even perimeter. The <strong>air</strong> spring (piston) is<br />
positioned onto the damper and pushed together<br />
with adequate force. The O-ring is forced onto<br />
shoulder 3 by the movement of the piston, where it<br />
supports and seals the <strong>air</strong> spring.<br />
