Speedo failure/Check Engine light

[Dan Z. Johnson]

Hello, Audi Fans
The dreaded Check Engine light came on today, and within seconds, I had
run through in my mind the myriad of emissions parts I had changed
recently. Then I had visions of money flying out the window at...what
speed was i driving? Oh, no, the speedo is dead! I switched off the
radio, listened for strange noises, then scanned all the gauges.
Everything seemed to be OK. The knot in my stomach eased up a bit. Then
the speedo slowly flickered back to life and, after about 10 seconds,
the Check Engine light went out.
Odd?
