Odd idiot light on this morning

[Danton J.A. Cardoso]

Fellow Audistas,

I have an '98 A4 with a 2.8 30V.  Last night it got down to single
digits and the car was parked outside.  Prior to that it drove for 170
plus miles at highway speeds, and was parked for about six hours in
weather that was in the teens.

This morning I started it, and it idled for about a couple of minutes
at 1350 rpm.  I hit the AUTO switch on the HVAC and fired up the
heated seats.  The coolant temperature light and chime kicked on.
Shut down the engine, and started it again, no light or chime.

Random fluke?
