Floor Mats Soaking,
I just had this today and the reason is a design fault.
BMW in there wisdom have put a joint between the front and the rear, ie. washer bottle and rear washer jet under the carpet.
Right then your going to have remove drivers seat and lift the carpets, as the "washer pipe joint" is between the hand brake and the drivers seat under centre console under the carpet.
I would think it's the pressure that blows the joint, either the cold weather or dirty / blocked rear washer jet.
Here's the question: Who in there wisdom would put a joint under the carpet inside the car. BMW.....
