2004 Volkswagen Passat with 1.8 engine

The water pump went out and info center warned to shut car down an check coolant with red temperature light illuminated. Replaced water pump, timing belt, thermostat and coolant. Restarted but can not get red temperature light to go out or info center warning to reset. Code reader shows no codes to clear. Need to know how to clear light and info center warning.
