I have this similar issue but I feel my draft is at the level of the seat cushion. I can put my hand between the side of the driver’s seat and the door where it meets the frame of the car. Absolutely chilly and can feel a draft at certain speeds. I mentioned this the the local service team but all they did was check the HVAC and told me the car pumped out hot air just fine.
Hi, @Neuner89.
Thank you for sharing. I DM'd you for additional information.
