Corrosion in Fusebox

Hi

Had an issue with the RCZ recently (they seem to be adding up lately), it had a throttle body position spring error, cleared but immediately came back.

While investigating we took the centre plug out of the fuse box right side of engine bay and there was a small amount of green (ie copper) residue in there and in the plug.

No obvious moisture, cleaned it carefully and wd40 and took it for a couple of runs last night and it seems OK

Mechanic thinks is could be an issue with windscreen or headlight washer leaking into the connector when used and capillary action drawing water up the loom.

Has anyone ever come across this or heard of it?? I found there was a similar issue on the 207 temp sensor

Anyone have ideas?

Thanks

There have been some reports of owners having spurious faults and having thrown everything at the problem only a replacement fuse box sorted it. So could be an issue🤔
