Re: color of anti-freeze

Well, maybe, but, as I remember, Audi changed to a lifetime antifreeze
sometime in 1996 that is RED--this according to the web page with the 1996
and later service bulletins. Red, brown, maybe there is room for compromise
in color definition. You can download the bulletin at

Brown.  Brown is not so good.  Green/yellow is more like it.  Brown makes
me think there's some oil leaking into your anti-freeze.  Possibly this
could be a head gasket issue.

Look carefully to see if the brownish stuff is floating on top of the
antifreeze, or stuck to the sides of the reservoir.  Oil doesn't mix with
antifreeze and will therefore remain separated.

You might also want to check if your engine oil cap has a milky brownish
mixture adhered to it.
