W251 Reversing Sensors issue

[ldare]

Hi

Are there any common fixes for the reversing sensors?

Ive 2 issues which I am sure are seperate, rear not working and front every now and again goes mental thinking something is right in front of my front right side.

I assume I need to replace the front right sensor, not sure how easy that is?

With the rear what should I start to check? any common issues?

Have you read any faults? - Parktronic is self-diagnostic, so it should tell you which sensor is playing-up.
