coolant sensor replacement on 2003 Audi A4 Quattro

My coolant light shows up on the panel as soon as I start the car in the morning and disappears in 10-15 seconds. It it a major issue or just the sensor gone bad ?

Start simple- check the coolant level in the radiator and the overflow tank. If both are at the proper levels, have your car checked for sensor issues.
call a tow a truck
Most likely your coolant level is low, you may want to check for a slight leak. In the meantime just top it off and monitor for a few days. If the light does come back on give us a call and we will check out for you at N/C. Hope that helps.
