Oh, you're right...it does say NTC in the WDS. I didn't even notice that. I'm not going to question the BMW engineers though it does seem counterintuitive. There must be a reason for doing it that way unless they were just lazy and generically labeled them NTC thermistors. The Range Rover link's description of the cantherm thermal switch sounds a lot like a PTC thermistor. Sounds like your elements' circular/disc thermal switches will be added insurance against overheating.
