My RRS (2013MY Red Edition L320) had a front inner sensor DTC (B1B42) thrown so I bought a 'set' from eBay and thought I'll just replace the 4 because if one had gone you can bet the others will also go soon after. So Removed the bumper and replaced all 4 , gave it a good clean up behind the headlamps and radiator area getting rid of all the bugs and crap usually congregating there. Got it ALL back together nice and tidy and after a re read and clear started the car and presto...ALL was great. Camera working as expected, no beeps or switches flashing. Sensors appeared to be working as I was close to the wall. Happy days!!!

Tidied everything up, put tools away and went back to the car. Started it up and 'horlicks'...lots of beeping and no reverse camera again! This time read codes and it is throwing B1B57 and B1B58 which says a power issue, short to ground. Never threw THAT before so have I got some dodgy sensors?

Disconnected everything and reconnected, cleared codes numerous times. Still no use.

I know this is probably a fix on here somewhere so if SOMEONE could point me a link in that direction I would be eternally grateful. Ready to buy a replacement PAM but hoping someone here has an answer. Thanks in advance
