Error GTW_w041 Cabin Heating Currently Unavailable

My 2016 X 90D Nov 16 build "True TESLA UNICORN" HW3 with Lifetime SC. It now has a new error that came up after the 12V was replaced by Tesla Mobile Service. GTW_w041 Cabin Heating Currently Unavailable, can anyone tell me does this mean the Front PTC heater core has gone bad and needs replaced or is this a FW issue. I have done all the reboots including the HV Safety loop removal and 12V Ground remove so the car rebooted completely. I cannot get this error to go away and I have NO HEAT at all. Rear heater in the X Sucks and never gets warm no matter what you set.
Car is running 2022.4.5.1

Update Tesla SC replaced the front PTC Heater Core behind the MCU, error is gone and have front heat again.

Thanks for posting this. I’m getting the same error now and about to book a service appointment now. Did you pay out of pocket, and if so, how much was the bill?
