I have a 1998 A4 2.8 tip w/51k miles on it.
I am having trouble starting the car when the engine is warm. If I drive to work (30 miles mostly highway) then turn off the car and let it sit 5-10 minutes then try to re-start it, it doesn't fire right up. I have to let the starter engage longer and sometimes give it a little gas. It then sutters and starts.

Now first thing in the morning it fires right up. When I leave the office at noon for lunch..no problem.

Any ideas?

Replace the coolant temp sensor

could you explain what this $27.86 part is and why it makes the car hard to start. This must be a common thing 'cause the dealer has one in stock. (and he doesn't like to stock parts!)

try starting the car with your foot on the gas (keep it pressed while holding the key) if the car starts, it's the coolant temp sensor

I think there's some sort of failsafe system that makes the car not start if there is no coolant
