Lots of us are experiencing it. On the minimum intermittent setting the wipers go at double speed? Then they don't self park properly? Have a look around the forum, the sensors within your wiper motor are faulty, if still in warranty get it booked in, if not be prepared for a bill of about £300.My wipers are set on the lowest sensitivity but have moments where they go crazy, although its hardly raining!
Anyone else experience this?
