Front right parking sensor fault

[DanPlumber]

Had a look on older threads but can’t find an answer
Van started playing up the other week
When selecting reverse long beep
(Park assist not working)
This also takes out all the parking sensors and the rear camera
Was happening Intermittently
Carista says front right sensor fault
Today took bumper off swapped sensor
Same fault
Swapped right and left sensors same fault (front right sensor)
Checked wiring and nothing obvious
Took out all blocks under passenger seat and behind bumper cleaned and put back together
Only thing I haven’t tried is the black and white connectors under the steering column
Has anyone any ideas before it goes back in garage (AGAIN!!!) and costs me even more money
Please

Check the wiring at the main plug that you disconnect when removing front bumper, you can access it easily by undoing bolts on drivers side wheel arch liner. I had the same thing , some of the wires are ultra thin and had broken very close to plug it was obvious to see.

I had took that apart and cleaned it before putting back together
May have another look tomorrow to be certain
Thanks

Hi Dan, Did you ever fix this issue, as I have the same on my T6?

Sorry for the late reply had a lot going on lately
It was a split wire to the sensor
All fixed now
