hi
its looking like i may have at least one parking sensor faulty (not sure if front or rear at the mo) and was wondering if it necessary to remove bumpers or can they be changed with out doing that ????
thanks will

I think you’ll struggle to replace them without removing the bumper(s) Got - 2017 SDV8 Autobiography in Loire Blue
Had- 2008 TDV8 Vogue SE in Java black
Had - 2007 S/C in Stornoway Grey

i was thinking that but was hoping someone had a little tip/trick to remove them ..never mind

getting this error code with gap tool B1B57-11 (2F) would this be a sensor or the wiring do you think ?
thanks

It could be faulty sensor or/and faulty wiring.
Its actually Front sensors power circuit - General electrical failure - circuit short to ground
Try first to give them a blast with WD40 it might displace any moisture etc 2018 SE SDV8 4.4 Byron Blue

thanks kot yea ill try wd40 fingers crossed it sorts it if not then bumper off and see where that leads it

tried wd40 no luck...how ever after replacing the park assist module and re-flashing it i now get a flashing orange light on the parking sensor button(didn't get anything before ) so some progress i did try going around to the sensors but couldn't hear anything from them

ok parking sensor module replaced correct firmware confirmed (patrick gap tool )..i now have no error codes no error tone when starting the car and no flashing parking sensor button but still parking sensors don't work ......anybody with more experience think of something i haven't ?
thanks
