Condition
Customer states:
• After leaving a relatively cool garage compared to the outside temperature, the parking aid activates and
detects “ghost” objects around the vehicle for the first couple of minutes when driving.
Workshop findings:
• No relevant DTCs are stored in the vehicle.
Technical Background
The parking aid sensors are temperature compensated.
To suppress false or jittery temperature readings, the vehicle’s temperature sensor output is dampened.
Therefore, when transitioning from cool air (like in a cool garage) into hot air, it can take a couple of minutes for
the temperature sensor to catch up with the actual outside air temperature.
This means, that in those situations, the parking aid sensors are compensated to an incorrect temperature which in
certain cases can cause “ghost” warnings.
