Etios PTC Heater Problem

Sounds like a PTC heater issue, I had similar symptoms on my Etios. It's like a broken thermostat – the engine struggles, and the system overcompensates.

Thanks. Could you tell me more about your experience? Did you see the same error codes, and what was the repair?

Yep, error codes pointed to the PTC heater. My mechanic confirmed it. I'd recommend a workshop. Cost about 350€ to replace the element. Like a faulty fuse box, a bad PTC heater can cause problems, so best to get it checked by pros.

Thanks for the info! I'll take it to a workshop for diagnostics and repair. Appreciate you confirming my suspicion and the cost estimate. Helps to be prepared.
