Ioniq auxiliary heater malfunction

I'm having trouble with the auxiliary heater in my 2016 Hyundai Ioniq hybrid (187316 km). The parking heater won't activate, and there's an error stored. Could this be a defective glow plug, or are there other things I should check?

Hey! I had something similar with my Ioniq. I'm no expert, but a few things could cause this. First, is your heat control set right? Sometimes it's something silly like that. Also, have you checked your temperature sensor? It might be giving a bad reading. What does the error message actually say?

Thanks! I've checked the heat control settings multiple times and they're configured correctly. Is the temperature sensor a common issue with these cars? The error message doesn't provide specific details, just a malfunction within the auxiliary heating system.

Yeah, temperature sensor issues pop up now and then, though not super common. Since you're getting a general error, and your settings are right, it's probably best to take it to a workshop. They can properly diagnose the heating system and see what's up. Good luck!

Thanks for the advice! I took it to a workshop, and you were right: the glow plug was defective, causing the auxiliary heater malfunction. The repair cost 440€ I appreciate your help!
