Peugeot 207 Auxiliary Heater Issue

Alright, Peugeot gurus, I'm pulling my hair out. My 2011 Peugeot 207 diesel, with 67764 km on the clock, has an auxiliary heater problem. The parking heater refuses to activate, and I've got an error stored in the memory. Climate control seems otherwise normal, heater core is fine, blower motor is blowing, but this auxiliary heater is throwing a wrench in things. Any ideas? I'm thinking maybe the glow plug is defective, but I'm open to suggestions before I start tearing things apart.

Sounds frustrating! I had a similar issue with my old Opel Astra. Different car, same kind of grief. Does it smell funny when you try to use it?

Funny smell? Hmm, I haven't noticed anything distinct. Can you elaborate? What did the smell mean in your case?

Yeah, mine had this weird, almost burnt plastic smell. Turned out a sensor was fried. Since you don't have that, and you suspect the glow plug, I'd honestly suggest taking it to a workshop. Auxiliary heaters can be tricky buggers.

Okay, cheers. I appreciate the input! Glow plug was indeed the culprit. Cost me 440€ to get it sorted, but at least the auxiliary heater is back in action. Thanks again!
