I have replaced the thermostat and flushed the system. Still no heat in the interior of the vehicle as well as continued overheating of the engine. Lower hose is cold when running, upper hose to the radiator is hot. When running at an idle the overheating does not trip the indicator lamp, temp is typically over 190 mark. When running at a higher RPM the engine will overheat and trip the sensor at approximately 240.

Did the deed and tore into the engine to replace the water pump. Thats what it was.
A cored out plastic part! I can't believe they used plastic.
Why does Volkswagen have to make things so difficult.
