I have a 2008/58 BMW 320d with pop-up washer jets. While washing the screen and lights on the M62 during a January snowfall both jets popped up a little too far and came out completely, last seen in lane 1 of the M62. My BMW dealer said I was the third person that day to report the same problem, but went on to add "clearly it isn't covered under warranty because of the weather", before estimating £200 for the parts, plus labour, to replace them. Is adverse weather really a valid reason to void warranty claims? Surely washer jets are there to be used when weather is bad or they wouldn't be needed? It wasn't even snowing, I was just washing the road muck off the screen and the light washers come on automatically. If my door handle dropped off on the motorway I'd expect a warranty fix (which Audi once did for me) so I don't really see the difference. But I'd appreciate your views and what steps I can take to argue the case if you think it's fair to do so.
