I had similar symptoms with my Eseries. Is the air from the vents colder than usual when you first start? Mine felt like the auxiliary heater wasn't working. Have you checked if the heating element is getting power?

Thanks for the quick reply. Yes, it feels like the heating element isn't getting power. How did you resolve it? How could you tell the heating element wasn't getting power, and where is it located?

Mine was a defective electric auxiliary heater, as you suspected. I didn't diagnose it myself. I'm no expert, so I took it to a workshop, and they confirmed it was the PTC heater. It's best to let an expert look, since you need special tools to reach the heater.

Thanks for sharing your experience! I took your advice and brought it to a local workshop. They confirmed the auxiliary heater was defective and replaced it for about 350€. Now everything works!
