The third time they replaced a sensor (which is what I suspected the problem was all along).

Also found this thread which seems to explain the cause of the issue quite clearly:

It describes my problem exactly, but NOT how my dealer fixed it. My dealer replaced two circuit boards after blaming the roof drains being clogged, and then a sensor the third time. Mine still leaks a bit and this antenna issue would appear to be the likely cause.
