DS3 Auxiliary Heater Issue

My 2016 Citroen DS3 with a gasoline engine has an auxiliary heater that won't turn on. The display shows an error in the error memory related to the heater. Has anyone else experienced this? I'm considering the glow plug, but I'm open to suggestions before I start working on it. The car has 247854 km. This car is driving me insane!

Sounds familiar! I've got a DS3 too, and I had a similar problem last winter. The parking heater wouldn't activate, and it turned out to be something simple. What exactly does the error code say?

The error code points towards the glow plug being defective, but I'm trying to avoid replacing it if something else is the issue. Did you also see any problems with the ventilation system or climate control? I'm trying to rule out other possible causes before I start ripping things apart.

No, the ventilation system and climate control were working fine. Just the aux heater refusing to start. Honestly, just get it checked. I spent ages trying to diagnose it myself, and it turned out to be a garage job anyway. It's probably the glow plug, but let them confirm. I was quoted 440€, but your cost might vary. Good luck!

Sounds like I'm heading to the workshop then. I'll get it sorted. Thanks for confirming it was probably the glow plug. At least I have an idea of what to expect cost-wise. I appreciate the help!
