Hi, my wife's 2010 Golf 118TSI has developed an electrical issue. Wipers don't work, horn sounds weird (possibly only one of two tones?) and activates itself when high beam is used. I have checked the fuse box as best I can with the limited information that VW provide and the help of older posts on here and nothing seems obviously amiss. Everything else is working fine. Thinking that I need an auto electrician but thought I'd put it out there first in case there's an easy fix.
