Self Study Program 280 – The Phaeton Auxiliary heater Thermo TOP C and supplementary heater Thermo TOP Z
VAG SSP 280. This self-study programme provides you with an overview of the auxiliary heater and the supplementary heater installed in the Phaeton. The use of heater units that work independently of the engine is continually rising. They are offered as an accessory for retrofit or as an optional extra by the manufacturer.
The petrol engine Phaeton features an auxiliary heater as an optional extra that heats the interior when the engine is not running.
For diesel engines, the Phaeton is fitted as standard with a supplementary heater that boosts coolant heating when the engine is running.
In this way, the operating temperature of the engine is reached faster and is maintained throughout operation at an equal level.
