Sorry to butt in on the repellent thread but with no posts am not allowed to start one just yet.
Does anyone suffer dripping condensation on their windscreen? Any suggestions as to where it might be coming from? This is on a 14 reg B180 when it is warm and humid, cold or raining. Dealer cannot find any signs of water ingress. All windows suddenly mist out, front one frequently ends up dripping wet and I can't see!
