My washers froze this morning with neat screenwash that said it was good down to -30ºc!
Just the nozzle, pipe popped off the back, and typically on my side as well.
The OBC was reading -9ºc and I guess with wind speed of 60mph it may have dropped to -30ºc?? I have no idea.
But I had to pull over and repair it as I couldn't see a thing. Luckily I had a Torx 20 in the glove box to get the trim off.
Managed to get through another 5 litres today alone, it is costing me nearly as much in windscreen wash as fuel at the moment.
