Audi heater cores

For a while the VW newsgroup has been discussing the problem with
VW heater cores.  Well, my heat has recently added a little perfume
to its air, and not a type I would recommend to anyone.  I posted
a question about Audi heater cores possibly having a similar
problem, in the hope that I wouldn't be out on my ear.  Well, I haven't
gotten anything yea or nay, but I did receive some interesting mail.
It seems several other owners have leaking cores, also.  
I am interested in how many Audi owners out there have had leaking
cores that they know about any time in their car's life.  
If enough cars out there have had problems, then maybe Audi will
consider
