It does sound like that. A wiring fault or some electrical problems.

Check the BSI isn't wet and check also the BSM module under the bonnet that has the fuses in it.

Some times the covers are missing and water gets it to the BSM.

Water has also been known to get into the BSI, but I don't know how, but worth checking.

Your faults look like they come from more that one place, so it could be a wiring loom problem?

Time to trade it in?

The haynes manual for the C3 (here on amazon) has good diagrams for the C3. But if the fault is with the COM2000 your relay won't help you :cry: :x
