X30/18 water damage

[MR.AMG]

Please help i had a no crank no start issue i traced the fault to the canbus x30/18 and x30/15 it had water damage on the wires. I have sorted the wiring but I still have the same issue the earth on canbus x30/18 was damaged too. The faults on my scanner are leading me back to x30/18 connector. "One or more messages are not available on the canbus. Please advise me
