Sorry all, can I just ask about the ecu suggestion please? I had it confirmed that one of the drain holes on the passenger side plenum had been blocked so we cleared it and there was signs that there had been water in some time. Sorry, I must have been too cold and wet to hear / notice.

However, the wiring from the wiper motor doesn't go into the ecu, it disappears behind the dashboard. If this is the case, why would the ecu be potentially the cause of the fault?

As yours is a diesel, a common cause of wipers having a mind of their own is the glowplug relay has got wet. It is next to the ECU.
Water shorting out the pins will backfeed a signal into the ecu via the Kbus which will in turn send spurious electrical signals all over the place, the wipers suffering more than most.

What would you suggest as a remedy or does the process you describe have the end result of damaging the ecu?
Thanks for your help.
