Okay, this time car is on warranty but smelled WIRING and noted burned part ground wire to aux heater in foot well.
From what can find is a Z32, VW acronym and did not code for short or open which it might not if a bad connection.
Might not go out much as dealer did not even know it there. UTUBE Showed the info I have stated and claim can pull as high as 80amps.
Once back will log on and see how it correlates to where temp senses is, and ITA, and ECT.
