Preliminary Work

  1. Remove cover for rear underbody → 519419 REMOVING AND INSTALLING COVER FOR REAR UNDERBODY .

    Information 

    Before starting to work on the PDCC system, always clean the underbody or at least clean the system components you will be working on. Ensure absolute cleanliness at all times. In other words:

    • Clean the system components to be removed using a power washer, for example. Ensure that the high-pressure spray is at least 50 cm away from the component (risk of damage to electric lines, connectors and contacts). 
    • Before loosening the hydraulic connections, the areas around the connections must also be cleaned carefully (e.g. using a brush and/or a lint-free cloth). 
    • If you intend to use the component again, the openings must be closed off immediately using suitable stoppers. 
    • If you are using new components, the stoppers must only be removed immediately before fitting.
