How to fix?

This is as designed from Audi. The battery has a heating options when DC charging. During DC charging, the high-voltage heater can heat the coolant if necessary. After passing through the heater and air conditioning unit, the heated coolant flows to the coolant changeover valve 2 N633, which sends it to the high-voltage battery, where its heat energy can be given off to the high-voltage battery. The heating circuit repeats after the coolant has flowed through the highvoltage battery. In addition, a minimum volume of coolant always flows through the coolant circuit for the electric powertrain. The high-voltage battery is heated at temperatures below approx. -10 °C.
