Default V50 - more woes

So the car has been stable for about 200 miles. Today wife tried to start it and had various warning lines. Quick scan with DiCE this evening gives:

BCM-0100
BCM-0115
BCM-E003

Only obvious thing is that we had heavy rain here last night for the first time in about a month. Before Christmas I'd tried my best to unblock the ends of the sunroof drains in the engine bay but had put off replacing the tubing with hose (to remove the weak spots at the joins). Could this just be the result of another soaking of the CEM?

Have you checked the usual culprit, which is the plugs becoming loose on the BCM? It's the white box with fuses in the passenger footwell, the plugs come loose and throw all sorts of lights, codes and electrical issues.

The white box in the passenger footwell is the CEM isn’t it?

Where about is the BCM?

BrakeControlModule - in the engine compartment, thats where all rigid brake pipes are coming out of (that area).
martin93 probably meant CEM though, yes thats the one in passengers footwell and thats the part that can cause a lot of issues if connectors are worn/loose.

Thanks.

Any idea of a possible root cause of those error codes and the steps I should be taking to rectify?

I have had lots of codes, even BCM related once. When replaced the pollen filter & removed the CEM and gave a good deep clean (to all connectors, checked all fuses by multimeter) all codes are gone....
Its been a few good months since and all good!
