Etios Auxiliary Heater Problem

Auxiliary heater on my 2016 Toyota Etios diesel (44634 km) isn't working. The parking heater won't activate, and the error memory shows an error. I suspect a defective glow plug. Has anyone else seen this?

I've experienced something similar with my Toyota Etios. Is the error code related to the heater system specifically? If so, it could very well be the glow plug, like you suspect. It's a common issue with these auxiliary heaters.

Yes, the error code points directly to the auxiliary heater circuit. Was the glow plug replacement the fix for your Etios?

In my case, yes, replacing the glow plug resolved the issue. However, it's best to confirm with a proper diagnostic check at a workshop before replacing any parts. The repair cost me 440€.

Thanks for the confirmation. I'll book it in for a diagnostic check. Appreciate the help.
