Hello , thanks for your question in the autoaid Community.
Your described fault Code means:

P1664 of electric heater (008) interruption (001) electric heater generator load signal P1664 is implausible.
P1664 (002) electric heater device error

These faultys doesn´t have an effect for the ABS/ESP.
Look in the ESP Control Unit if there is a fault Code.
