Defective Sensor

As with dirt and dust obstructions, improper sensor operation can result in mechanical damage.

Naturally, it is also possible for a sensor to fail.

Excessive amounts of dirt and dust can distort the signal from ultrasonic sensors and disable the system. Occasionally, this will also happen after washing the car as dirt particles gather up at the sensor’s edge. Usually, cleaning the sensor with a clean cloth solves the problem.

Software Issues

In some cases, a software issue can cause problems with parking assistance. As a result, the system will malfunction only in specific situations, such as parking in a tight space. This can be solved with software updates as BMW continuously develops software solutions.

Control Module

On almost all BMW cars, the control module is installed in the trunk next to the battery. If, for any reason, water floods the boot, it will also fill in this compartment. As a result, corrosion and other buildups can occur within the control module. One solution is to open the module and clean all traces of corrosion.
