[V6-12v] Bad Ignition Switch

[Wilfried Link]

I replaced the ignition switch in my A6 with one from
AutoHaus AZ three weeks ago. Last week my windows and
numerous other electrical items lost power until I
manipulated the key in the ignition. It happened again
today -- including grinding starter noises. I suddenly
vaguely remembered reading a 12V email from someone
describing the same problem with a switch from
Autohaus AZ. Is that someone out there? What was the
end result? I'd hate to do the job all over again.
TIA,
