Refitting

- Deactivate the self-levelling suspension control system by simultaneously pressing the two adjustment buttons in the dashboard (for at least 5 secs.) and the LEDs in the buttons should both come on constantly.

- Position the vehicle on the lift.

1. Slightly undo the connector (1a) for the compressed air pipe on the reservoir (1b) until the pressure in the circuit is completely discharged then undo the connector completely.

- Remove the control unit / compressor module guard.

1. Undo the connector (1a) for the black compressed air supply pipe (1b) to the air reservoir from the control unit/compressor module.

1. Release the pipe (1a) from the clips fastening it to the chassis, then remove it.

1. Remove the inner tapered seal (1b) from the air pipe (1a), then release the rapid connector (1c) (at both ends of the pipe).

The connector is ruined during the removal so it cannot be kept but must be replaced with a new one.

Removing

- Check that the pipe is not damaged, otherwise it must be replaced.

1. Tighten a new rapid connector (1a) with a tapered inner seal (1b) on the control unit/compressor module.

During this operation take great care to fit the connector properly on the thread to prevent possible damage to the control unit/compressor module.

1. Tighten a new rapid connector (1a) on the compressor air reservoir with a tapered internal seal (1b).

1. There are two reference lines (1b) and (1c) at the ends of the air pipe (1a); insert the air pipe about 20 mm into the rapid connector (1d) for the control unit/compressor module or at least sufficiently to leave only one line (1c) showing.

Once the pipe is fitted it cannot be removed without replacing the actual connector.

1. Secure the pipe (1a) to the clips fastening it to the chassis.

1. There are two reference lines (1b) and (1c) at the ends of the air pipe (1a); insert the air pipe about 20 mm into the rapid connector (1d) for the compressed air reservoir or as far as necessary to leave just the one line (1c) showing.

Once the pipe is fitted it cannot be removed without replacing the actual connector.

- Position the control unit / compressor module guard.
