How do you bleed heater system on vw sharan?

To bleed the heater system on a VW Sharan, first ensure the engine is cool and the heater is set to the maximum temperature. Start the engine and let it reach operating temperature, then open the bleed valve located on the heater hose or near the radiator, allowing air to escape until a steady stream of coolant flows out. Close the valve, check the coolant level in the reservoir, and top it off if necessary. Finally, run the engine again and check for any signs of air in the system or leaks.
