Just purchased my first Audi, 2002 A4 Quattro V6 and 6 gear manual with a more recent engine and trans. I am looking for an owner manual. Is there only one version of 2002 manual or each A4 version had its own manual?

 

Each year has it's own manual and generally there were only a few changes year to year. What do you mean more recent engine and tranny -- were they replaced?? Try eBay or even a few parts yards. A dealer may be able to order one.
