Resetting Oil Service Indicator

["Levis-Fithian, Jeff E" <LevisJE@LOUISVILLE.STORTEK.COM>]

My trip odometer display on my 95 A6Q is flashing "OIL" for about 10 seconds
when I start my car.  The oil level is fine, so I'm assuming this means that
I need to go to my local Audi dealer and pay $60 for an oil change.
However, I have blatantly ignored my owner's manual recommendation not to
perform such a complicated repair procedure without 2 years of factory
training and have gone ahead and changed the oil myself (OEM filter and
Mobil 1).  The question is, how can I reset the service indicator?  Do I
need to humbly go to my dealer and ask them to reset it?  I wasn't able to
find anything in the Bentley.
TIA!
