Indecisive temp gage needle

[Gregory Coe]

Replace your coolant temperature sensor.

It's a very inexpensive and easy to change part, and they are very failure
prone.  I just replaced one on my A4.  Cost about $6.00 and 5 minutes of
work.

The faulty sensor may cause your car to run rich if it's reading cold.  The
car may never get out of cold-start mode, where the mixture is kept slightly
rich.  This will surely affect your gas mileage over time, and may affect
performance somewhat, although not significantly.

Best regards,

Greg
