LandCruiser rough cold start

Hey, I'm having a weird issue with my 2007 Toyota LandCruiser diesel. It's only got 70422 km on the clock, but recently it's been running rough when cold starting. The error memory has stored an error and fuel consumption is higher than normal. My mechanic thinks it might be a defective PTC heater. Anyone experienced similar temperature control issues?

I've had a similar issue with my LandCruiser. Does the poor running smooth out after a few minutes? And have you noticed if the blower motor seems to be working fine, just no heat?

Yeah, it smooths out after a bit. Blower motor seems fine, plenty of airflow, just no real heat initially. Was it definitely the electric auxiliary heater causing your cold start issues? Did you also see elevated fuel consumption?

Confirmed, same symptoms. The electric auxiliary heater was the culprit. Error code pointed directly to it. Regarding fuel consumption, yes, it was noticeably worse before the repair. I recommend getting it checked at a workshop; they should be able to confirm it.

Workshop confirmed it's the PTC heater, and it's gonna be about 350€ to replace. Thanks for the help!
