Well done, jkspoff! :D Do you feel that sense of a job well done as well as saving a few quid? :D Its not meant to come apart. VW sell the plug/washer togother for 90p. But to be honest, I've never found a great need to change the old one... Well, if youre a pedantic/perfectionist, then yes, but any more than 2/3rd full and it makes a mess screwing it back on.. Not sure you can do this on the new style PD engine filters as it may just drain back to the sump... :lol:
