Re: Replacing mirrors


    When you say "rusty mirror", I assume you are referring to the
delightful sepia tone which spreads in ever increasing artistic patterns in
the external mirrors until the mirror glass falls to the freeway at 140 kph,
returning to the silica sand from whence it came?
    Note that Audi changed the external mirror construction around '89
sometime. The old heated mirrors had the glass bonded to an aluminium
backing plate. The newer heated mirrors have the mirror glued to a plastic
backing plate. The newer mirrors are not well sealed, and the silvering
corrodes and separates from the glass, giving a rusty look. The older
mirrors are much more durable and, although they use a different mount
 rotating locking ring vs new plastic snap clips), the newer mirror drive
will take the old mount and the old mirrors fit right in. I have replaced my
drivers side glass which had "rusted" with one from my '86 5ktq ( I saved it
from the wreck because it was convex - probably for a RHD car fitted by
mistake - great view and no blind spot). The old mirror is in perfect
condition - no sign of "rust".
