Washer Bottle Cover for VAG applications polished Productomschrijving These alloy Windscreen Washer Reservoir caps are a real treat. Made from billet alloy, they are designed to replace the original plastic cap ( shown below ) as found on most Volkswagen, Audi, Seat, Skoda models. This will notfit the MK1 or Mk2 Audi TT though. If you wish to check compatability before ordering, the lip on the neck of the washer reservoir needs to be approximately 51 - 54 mm in diameter. We can supply our alloy caps in either polished or finished in anodised black. Simply select your prefered choice in the options below.
