Make sure that the repair work is performed carefully. Otherwise, renewed leaks may occur.

In the event of damage to compressed-air terminals (1a) and pressure lines (4) a compressed-air connector (3) or a repair screwed connection (1) can be mounted.

Remove compressed-air line connection (1a) using the socket from the affected component (e.g. suspension strut).
Cut pressure line (4) using an isolating blade to a suitable length.
Special care must be taken to ensure that the cut is exactly at right angles to the pressure line (4). Otherwise the pressure line (4) may suffer more leaks.
Plug pressure line (4) all way on up to end stop or at least 19.5 mm into the pressure line connector (3).
Pull back pressure line (4) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the pressure line (4).
Cut repair line (2) so that the original length and form (straight end or 90° curved section) of the pressure line (4) to be repaired is reached again.
When cutting off the repair line (2) take into account the insertion depths in the repair screwed connection (1) and pressure line connector (3). Leaks can occur otherwise.

Special care must be taken to ensure that the cut is exactly at right angles to the repair line (2). Otherwise, renewed leaks may occur.

Do not kink pressure line (4) and repair line (2). Otherwise, the pressure line (4) and the repair line may be damaged (2).

The Replacement Parts Unit supplies a repair line (2) with a straight and a curved section.
Plug repair line (2) all way on up to end stop or insert at least 19.5 mm into the pressure line connector (3).
Pull back repair line (2) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the repair line (2).
Screw repair connection (1) into the affected component.

Pull plastic guard (1c) out of repair connection (1).
Insert the repair line (2) into the repair bolted connection (1) up to the end stop or insert at least to 19.5 mm into the repair threaded connection.
Pull back repair line (2) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the repair line (2).
Route pressure line (4) on vehicle.
When pulling in or routing the pressure line (4) on the vehicle make sure that the pressure line (4) cannot be twisted once fastened.

A twisted pressure line (4) can be damaged and consequently be leaky.

Leak test after filling AIRmatic
Check repair point using leakage spray for leaktightness.
Wait for approximately 10 to 15 minutes after spraying the leakage detection spray. This allows smaller leaks to be detected (bubbles form). Larger leaks are visible immediately.

In the event of leaks:

Check whether the pressure line (4) or the repair line (2) is plugged in up to the end stop.

If, despite a properly mounted pressure line (4) or repair line (2) bubbles continue to form, then the pressure line connector (3) or the repair threaded connection (1) may be faulty. In this case:

Replace pressure line connector (3) or repair threaded connection (1).
Fasten pressure line connector (3) in place using cable tie.
Fasten pressure line connector (3) using cable tie to suitable position on the vehicle.

Otherwise, the pressure line (4) may be damaged by chafing or a loose pressure line connector (3) may generate noise when driving.
