Piter, while my car was double checked at the car dealer I got a Taycan and I really loved it, If I was in your situation I would really consider it, just in case youwant a change after all.
ps: i just read you did buy a Cayenne congrats
I'm experiencing the same issue here in Spain with a Macan 4. It’s not smoke, but there’s an ugly burnt smell when the heater is set above 23°C on the highway. Now at the dealer. I also had to constantly turn on the defrost button. Any updates on your Macan, @piter95
