Washer Bottle Blocked
335i E92 purchsed from main dealer Dec 2006. 11k miles. Recently screen wash wipe failed i.e. no water getting to screen though I could hear the little motor whirring. Main dealer advised some "crystallisation" was evident in the pick up/filter area in the washer bottle and advised not a warranty item. Cost me £100. I have only filled the bottle twice maybe three times since new. BMW UK wont pay under warranty and are refusing to budge. their position is that its not a manufacture issue. Car is garaged every night. The wash/wipe is now stronger than ever, though previously I had no reason to believe there was any problem. They have failed to reply to this point and dont want to enter into further dialogue. Anyone had similar experiences and do I have a point? Thanks.
