Complaint:
In vehicles with AMG Styling Package (SA code 772), warnings are issued without obvious cause (visual and acoustic) by the front parking sensors, mainly on the left-hand side.
Cause:
Possibly SCN coding in parking system control unit "N62" relating to sensor sensitivity.
The reasons stated below may lead to problems that must be noted:
1. Accessories license plate number frame mounted to front bumper.
2. Front license plate number incorrectly aligned.
3. Furthermore, removable accessories that are located in the range of the PARKTRONIC sensors.
4. Reduced vehicle driving height, which results in echoes from the ground.
5. Snow, slush, hailstones, sleet, heavy rain.
6. A gush of water that runs over the vehicle hood and down the parking sensors when braking.
7. Sensors badly soiled.
8. External ultrasonic sources such as air brake systems, compressed-air hammer, brake squeals from a vehicle in
the immediate vicinity, etc.
9. In underground electric induction loops, at traffic lights or in parking garages.
10. Waste heat from overheated engines (exhaust) form in front of vehicle when it is at a standstill.
