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.

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.
