I have a 2004 Audi A6 Quattro. I saw wax (or may not be, but like wax)
buildup on my garage floor. After checking up under, I saw the leakage from
the bottom underneath engine. Anyone has any clue why it is happening? Is it
Audi fills some open spaces in the body (like doors) with wax to
reduce rattling and such. It leaks out when it gets hot and runny,
but only where the fill holes have somehow opened up (unplugged).
