Peugeot 508 Diesel Cold Start Issue

I'm having trouble with my 2010 Peugeot 508 diesel. Engine's running poorly during cold starts, the error memory has a fault stored, and fuel consumption has increased! I suspect it's the PTC heater. Mileage is at 108755 km. Has anyone else experienced this?

Sounds familiar! I had a similar issue with my 508. Is the temperature gauge taking longer than usual to reach normal?

Yes, it definitely is! It takes ages to warm up, and even then it's not great. Did you find it was the auxiliary heater?

Yep, it was the electric auxiliary heater. It was defective. I'd get it checked at a workshop; it's the likely culprit.

Appreciate the confirmation! I booked it in, and you were spot on – PTC heater was indeed faulty. Cost me 350€ to fix, but at least it's running smoothly now!
