Starter Problem During Normal Operating Temp

[mcarruthers]

Hey guys, I seem to have a problem with my 92 tsi awd. Car seems to start fine every time except when it has warmed up. After the car reaches normal operating temp. and I crank it over it starts fine but makes a couple quick grinding noises, as if the starter is still trying to engage. Just looking for some pointers on where to start looking.
Thanks Matt,

This article is very helpful. The problem is most likely your coolant temperature sensor.

Just to make sure I have a general idea. My coolant temp switch could be acting in a way that on a warm start, it send too much fuel (as if it was a cold start) and keeps the starter engaged a a split second longer?
Is this correct, or am I way off?
Thanks for the response.
And just to clarify, it's not a no start, it starts and runs fine, but a slight grinding noise for a split second on a warm start.
