Skoda Fabia Parking Assistant Issue

That sounds frustrating! Have you checked the connections to the ultrasonic sensors themselves? Sometimes a loose plug can cause that error. Is the rearview camera also affected?

Where exactly are those ultrasonic sensors located? And could faulty wiring also affect the blind spot sensors, or are those on a separate system?

The ultrasonic sensors are usually located in the bumpers. And yes, faulty wiring is very often the culprit. However, the blind spot sensors are usually a separate system. My suggestion would be to take it to a workshop to have them check the wiring.

It was indeed a faulty wire to one of the parking sensors. 95€ later and it's working again. Thanks for the advice!
