I took the loom off the rear to check for splits and all looks good. Each Brown and red cable was giving around 14v so I’m a bit stumped.

Probably need 2 new sensors if that’s what the fault code says

If you have a gap iid
Read live values and see which sensor is reading short distance

Don't buy those cheap Chinese sensors. They are rubbish.

A cheaper icarsoft code reader will be able to tell you the distances the computer thinks are there.

I had similar problem. Rear buzz going off like crazy. I thought and tested all the rear sensors, module, loom... etc.. finally got a code reader which told me "power circuit fault rear and front" it turned out a front sensor was short-circuited and brought everything to stop.
Code reader is definitely a worthy investment.

Good luck.
