rear parking sensor [again]

[stopper]

Good Morning,

Stype 2006 3ltre,  I have an anomaly with my rear parking sensor,[new/used module worked perfectly for over a year] now it is very intermmitant i.e.when the battery is fully charged with my Ctec {green light} or when I have driven a longish distance. No other faults just rear parking .  Anybody got any thoughts? I did think of the fuse but the they either work or don't work.

Thank you

Hi, I've had the same, it could be moisture ingress in the sensor head itself. I've had to have one replaced in the past for this reason.
