My audi S3 is due an full Haldex oil and filter change. Ive got the removal tool, filter and one 275ml tube of haldex oil. Ive got one question. How much oil does the haldex require is 275ml enough from empty? Ive seen on the internet i need 1litre or 600ml or 3 x 275ml tubes? Im unsure what i need. Any help would be excellent. Also there is a separate part of the haldex that uses diff oil? How much and what oil is required there? Thank you.
