thought it was just a an accident now I am getting concerned.

Every few days when I turn on the car after driving than stopping the
head lights dont go on again.  Simpley turning off the ignition and back
on again fixes it.  The same has also occured with the dash outside temp
indicator and the window switches at the same time.

My guess is its a bad relay someplace.  But since it has happened on more 
than one circuit this is puzzling.

Any idea where to start diagnosing this one?

Please dont tell me that Audi has subcontracted out their electronics to
Microsoft.  Say it isnt so.>>

As fashionable as it is to blame every electronic problem in the world on 
Bill Gates, this one is just caused by a piece of crap ignition switch.
They are about 30.00 at the dealer. They will probably charge about an
hour to put it in.

If you do it yourself, follow the airbag service rules in the service
manual to the letter, or you might wind up with an airbag light that
needs to be cleared with one of the VAG specific scan-tools. But this is
a very do-able project at home. It is done through the instrument cluster 
hole and takes less than an hour, even the first time. The archives have
a number of detailed descriptions.
