Audi A4 coolant warning indicator illuminated? Don't worry if you see the switch off engine and check coolant level message if the engine is not overheating. The Audi A4 coolant bottle contains a sensor which illuminates the coolant warning light on the dashboard if the coolant level is too low. This video shows how to top up the coolant tank in a 2014 Audi A4. The procedure is the same for the Audi A3, Audi A5 and Audi A6 (and other similar VW Audi group vehicles).
