Default C70 Park Assist "just not working"

Good afternoon,

As the title suggests, the park assist is not functioning and I need some suggestions. Here is where I am at:
  • None of the sensors are active (ie. no noise from them)
  • The reversing lights function correctly upon engaging reverse gear
  • When engaging reverse, the infotainment system says the system is active
  • If the fuse is removed, the infotainment system does not indicate system is active
  • No codes have been stored in the park assist module
  • Park assist was not manually disabled - it just stopped functioning
The removal of the fuse and subsequent loss of the message about park assist being active suggests that the module is basically communicating with the bus, so I'm thinking possible faulty module.

Whatever it is, you can imagine my surprise when I reversed into my garage and the "auxiliary reverse sensor", also known as the tow ball, activated first!

Any thoughts or suggestions appreciated.

Need to connect to Vida to find out what sensors are not working and replace. Only needs one to not work to stop the whole thing to not work

As mrfixer said.

I couldn't hear any sounds from mine but Vida flagged up sensor 4 faulty.
New one for 10 from the bay and all was good.

Unfortunately, the PAM is not showing any error codes, which is a VIDA readout.
