What type of brake fluid does volkswagen passat 2006 model use?

lost my owner manual and just wonder what type of brake fluid does the 2006 volkswagen passat use. thanks.|||DOT 3 or 4 ( either will do) and either OEM VW, Valvoline Synthetic or Castrol LMA|||DOT 4. The previous writer discussed Castrol LMA, its an excellent choice and has a minimum wet boiling point of 311 degrees F, far exceeding the standard DOT 3 of 284 F. I personally, use the Castrol LMA in my own cars.|||you can't mix synthetic DOT 5 brake fluid with DOT 3 or 4 fluid go to your local VW dealer give them your vin number and they will sell you the right fluid
