Installing control module - AZ54.65-P-0001-04T

Depending on the vehicle version, the PTS control module (N62) is either:
1. Clipped onto the existing control module bracket (16) in the left side of the trunk, if this bracket is fitted.
2. Screwed onto the left D-pillar with 2 sheet metal screws (4 mm dia.) in vehicles without bracket.
  In case B , position the control module as shown in the diagram, mark the hole pattern and drill the holes. Prime the drilled holes.
