Ben - If you have de-activated the RLS both on the MIB and the stalk and the wipers still sweep automatically, - it very much sounds like a real fault. I guess the tricky part about the dealer's diagnostic search for the fault will be the intermittent nature of the problem!!
Nevertheless, I don't believe that this is a matter that can (or, should be) tackled as a DIY fix

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.
