Audi maintenance, tips, etc.Windshield wipers / washersI had a 2002 A8L and I remember the sensor in the washer tank went bad. The dealership wanted to blame it on the windshield washer fluid used. So with my "new" 2014, I decided to only use the fluid recommended in the manual. It is part number G 052 164 M2 washer solvent with anti freeze. Cool, but looks like it has some alcohol in it. Makes sense since the manual references solvent so the nozzles don't plug up. Great, but wait, you cannot get it in California any more, and I had to order from another dealership out of state. It's getting scarce, and be careful, the first place I went wanted $60 shipping because of "hazmat".
