[A4] Apparent Ignition switch malfunction

[Brizax at aol.com]

have you tried wiggle'n the switch as the problems happen to see if  anything 
changes? i have heard of a lot of switch's going out on the vw's,  specially 
those with heavier keychains

Thanks  guys. All things are pointing towards the ignition
switch.  This  morning I got more "clunks" and the turn signals
work again.  No  starter, but given the commonality of problems
here, but I really don't  think the problem is in the relays or
the starter itself. (a quick voltage  check at the starter would
help determine that for sure).

Is this a  field-repairable part or am I a destined to fork over
$600 to the Audi  dealer?  Can I have another non-Audi shop
repair it?  (visions of  Seinfield's mechanic coming to mind)
