Installing Wing Fastening Rail

Information 

In the case of the Cayenne Turbo, the undersealing in the area of the outer lower side member is painted in the colour of the vehicle. This means that after priming the repair area on these vehicles, undersealing must also be applied to this area.

1. Prepare repair part.
   1. 1.1. Cut off the top part of the new wing fastening rail. Ensure that the repair part in the area of the cut overlaps by -W-  → Overlap: 50 mm  over the remaining part of the vehicle.

2. Clean welding and sealing areas.
   1. 2.1. Grind both sides of the connecting flange of the new part in the marked areas until bare using a rotary brush.
3. Drill holes for plug welding using inert gas.
   1. 3.1. On the fastening flange in area -N-  , drill holes with ø = 7 mm or punch them with a hole punch. Maintain spacing as on the old part.
