Hello all, I have a 2014 Q7 TDI that I cannot figure out a no heat condition to the heater core. Coolant level is full and engine holds temp nicely but there is no hot coolant flow to the heater core hoses. Checked operation of the Aux coolant pump and shut-off valve inside the fender well as well as flushed the core to ensure no blockages. No signs of bad coolant from the core. Both inlet and outlet hoses are cold when the car is at temp
