Technical Service Bulletin
The adhesive strength of the
parking aid bracket is not sufficient.
Over time, one or more of the
sensor mounts may separate from
the rear apron.

Figure 1: The parking aid mount has come loose.
It is possible for the parking aid
sensor(s) to issue false warnings
when the mounts start to separate.
For a customer concern relating to
false detection of obstacles it is
important to check each of the
sensors on the rear apron for
correct installation.

Production Solution
Optimized process during production.

Service
If one or more of the sensor brackets has come loose from the rear bumper, use the steps below to re-attach the
mounts.
Note: If the mount is missing or damaged the rear apron will need to be replaced.
Prep work:
• Remove the rear bumper cover according to the repair manual.
Note: If multiple brackets are loose, ensure each bracket stays in the same position. Each mount needs
to be re-bonded in the same position and orientation to the rear apron.
• Remove the old adhesive tape from bonding surfaces of the rear apron and affected brackets.
• Lightly sand/scuff the bonding surfaces of the apron and mount(s).
• Clean the rear apron and mount(s) thoroughly with plastic cleaner D 009 401 04 or equivalent (isopropyl
alcohol) and allow to dry for 5 minutes.
• Apply a thin coating of primer for plastic components D 822 150 A1 to rear apron and bracket, allow to dry for
10 minutes.
• Prepare all affected brackets up to this step prior to bonding.

Bonding the mount(s):
Apply plastic adhesive D 180 KU2 A1 to
areas marked by arrows between the
parking aid bracket and rear apron (Figure
5).
• The first 3-5 cm of adhesive from the
mixing nozzle may not be properly mixed
and must therefore be discarded.

Figure 5: Arrows mark location for adhesive.
• Tighten knurled nut -3-.
• This results in clamp -2- pushing tabs of
bracket -4- flat onto rear apron/spoiler -5.
• Perform this step for all affected
brackets.

Figure 6: Mounts compressed to spoiler.
• Allow a minimum drying time of 30 minutes before removing the jig.
• The rear apron must be left undisturbed during this period and must not be moved.
• Re-Install the rear bumper cover and confirm system operation.
