Weird Smoke and Burning Smell from Air Vents in My Macan 4 – Anyone Else?

[shawn]

At speed you have wind and increase power so if is not wind then some component is burning off some lubricant (like a fan motor coil). Otherwise you have an electrical component burning out for some reason. I would have a chat with your service agent. If they said it is normal then they should have an explanation. I bet given these cars are new some excees lubricants was applied during production and is burning off. If the smoke and smell dies down then that is the reason. I could tell if I could smell it and so could your service agent. But again I would insist they do that especially if it is same or worse each time or even starts happening at lower speeds. Hope this helps

I will definitely wait for some of their answers. I don't accept anymore "it's normal", "nothing found" etc. If this will happen again I will go to a different dealership and if the different dealership will find an issue, I will sue the dealership from where I purchased the car.

Main thing is you wanna rule out the possibility of an electrical fire by some component. The only thing I can think of from the same dealer is if they pressure washed where they should not have and pushed water into the wrong place.

I have honestly no clue... All of these are great guesses... I think there are some electric components that are not properly working... Now and then I get the message that Safety system are malfunctioning. See pic below:

Assistance systems usually limit themselves if water or dirt is on a camera or visibility is bad.

Could be... I was driving on highway and it happens when I came back home, so maybe insects and dirt... But after shutting down and turning on everything was fine

Yeah moisture or fog build up can throw the error. It evaporates and reset should not be necessary but can speed up getting it back to normal

Ciao Diego!

Interesting! Did you have chance to have the clima ON around 25 degrees or higher, 1 of speed and driving for 40km minimum at 130KM/h (Highway driving) ?

I'm just thinking that may be the clima... At least I hope! But from the dealership apparently I'm not the only one...

Hi Pietro, tried what you suggested yesterday night (very cold - around 2°C - and foggy. No traffic so high speed for long period wasn't a problem, internal temp set to 26 - too hot for me but I had to test - clima on). No smoke or smell

Thanks Diego! Really appreciated that!
how many kms did you drive?
I really wonder what’s the problem in my case… I guess I will discover it soon…

I’m going in holidays for 2 weeks, so they are keeping the car and I hope once I’m back that they figured that out…
