Re: Battery replacement: 1995 A6

[Osman Parvez <oparvez1@nycap.rr.com>]

David,
      Worth looking into. The battery in my mother's 1996 A6q decided to
crap out somehow which required a full flatbed tow approximately 70
miles to the nearest dealership, and replacement under warranty. This
was after only 36K miles. Luckily it was covered under the Audi
Advantage (if it hadn't been, we would have just bought a replacement
locally and installed it).

P.S. It seems to me that Audi failures are almost *always* systematic
and not isolated "random chance" events. In other words..if one battery
on an A6q fails..others are sure to fail too.
