Ah cool, a solution found!
Yeah that is really bizarre coding it out doesn't work, but disconnecting it does! It must need coding out at a deeper level then, similar to when engine sensors are coded out.
I went through a spell of broken windscreens. 3 in 6 months. Each and every time the fitter f'cked up the sensor pad that sticks to the glass, so my wipers have never been right since. This is a good fix!
Does it take out the night sensor as well? Not that I ever use that function, because erm, I was born with the gift of sight and know when it's dark!!
