Are you getting BMW Parking Assist Malfunction, Auto PDC failure, and no parking assistance displaying on your iDrive screen? BMW PDC Parking Assist Malfunction means that the Park Distance Control system in the vehicle is not working properly, which can result in the system not providing audio and visual warnings when the vehicle is getting close to obstacles while parking. This could be caused by a variety of issues, such as malfunctioning sensors, damaged or corroded wiring, a faulty control module, or a software issue; it is recommended to have a professional mechanic diagnose the problem and suggest the appropriate solution.
BMW parking assistant uses ultrasonic sensors to measure parking spaces on both sides of the vehicle and incorporates the Park Distance Control system. Anytime the car speed is lower than 22 mph, it observes the potential parking spaces. It also takes over the steering, braking, and acceleration during parking.
What Causes BMW Parking Assist Error Message?
“BMW No Parking Assistance, please park unaided” may come on for one of the following reasons.
As with dirt and dust obstructions, improper sensor operation can result in mechanical damage. Although a slight impact on the bumper might not leave a visible trace, it could push the sensor out of its place. The result will be incorrect readings and possible system failure. 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.
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.
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.
Active Power Steering
The park assist system uses an Active power steering system to operate the steering wheel. Unlike traditional hydraulic systems, this one uses a powerful electric servo motor to aid the driver. Any issues with it will result in an inoperable park assist system.
