Hello , thanks for your question in the autoaid Community.
Your described fault Code means:
P1664 of electric heater (004) short-circuit
P1664 of electric heater (008) interruption (001) electric heater generator load signal P1664 is implausible.
P1664 (002) electric heater device error
P1664 (032) electric heater power amp error
These faultys doesn´t have an effect for the ABS/ESP.
Look in the ESP Control Unit if there is a fault Code.
