Inside the bumper covering are four cross-wire or circle markings to permit mounting of the sensors. The drilling
positions are the centre points of these crosses or circles.
Center punch the drilling positions on the bumper covering and drill by using a ∅ 2 mm bit.
−
Use a ∅ 20 mm Forstner bit to drill the holes -A- from the outside.
−
To prevent rotating of the sensors, an upward-pointing notch -arrow- about 1 mm deep is needed in the holes.
File an upward-pointing notch -arrow- with a small triangular file in all four holes.
−
Remove the swarf from the holes for the sensors in the bumper covering.

Note
If a wire and wiring grommet are already fitted (e.g. for vehiclew with trailer equipment) rather than a plug -arrow-,
remove the wiring grommet from the supplied sensor harness. Make an extra hole in the existing grommet and route
the sensor harness through this into the vehicle interior. Seal the extra hole in the grommet with a suitable sealant.
A4 Avant and A4 allroad quattro only:
Page 3 - figure 4
Remove the original plug -arrow-.
