Hi
You dealt with this problem because I have a similar one

[huwalsh]

Seen similar before was wnit mounted to battery box , it is a series of solid state relays and that was faulty. This was on a 2018 308 think c4 has similar setup

Carefully check the BPGA block. And an intelligent sensor on the minus.
