Can anyone point me in the right direction?
I have had problems in the past with my Parking sensors but was able to fix them by replacing single sensors. I’ve also had a problem that was rectified by replacing the rear sounder but I knew it was failing because it was making an odd noise.
I suspected my issue was different to the normal parking sensor failure as my system gave a long error sound as soon as I turned the car on. In the past when it failed, it only gave the long error sound when I selected reverse.
Having replaced the pdc module in the rear, removing the rear bumper to check the wiring, replacing the rear sensors (with one new one- one at a time) the problem persists.
I have had it plugged into a diagnostic reader and the errors are B1B57 and B1B58.
I’m looking for advice on where to go next. I have heard of some people turning off the front sensors on CCF to determine if fault is in rear or front. How exactly is this done?
Has anyone else had a similar problem that they were able to get to the bottom of?
I’ve also read that it could be still a sensor shorting out but was looking for direction rather than replacing them all! Thanks in advance

To select only reverse sensors, this is done with a GAP IID (£405) (in CCF settings)
However, remove the drivers headiight, unplug the colourful park sensor plug.
Clear the fault codes
Select Reverse
It will now complain about 4 front sensors missing (and maybe front open circuit), but the key question is, has the short failure gone? If yes, its one of the front sensors or front loom. >>>
purchase a new sensor,
remove front bumper
unplug all sensors.
reconnect loom by headlight
reconnect 1 sensor at a time.
select reverse
and see if short circuit comes back. (you maybe able to tell by the error tone) REPEAT (connect next sensor). when it does, you found the faulty sensor. replace.
Otherwise the loom could have chaffed on front bumper metal work
