It's probably normal because like i wrote in my early reply, my father macan is bone stock and he has the same sound just on a lower tone. The fact that both of us would have the same problem at the same time... I'm sceptical. I will try tonight to put the stock filter on to see for myself. Just didn't had time recently.The fact we are all reporting this same sound coming from the left (drivers side, US cars). I’m hoping it’s normal and people usually don’t notice it and only more Pronounced with the intakes.
Maybe but each oil change i make sure to verify for any oil leak to make sure if ever it happen that i caught it as soon as possible. For now everything looks good underneath! Let me know if they find anything after your appointment!Could it be a cause of the (well known) timing cover bolts breaking and causing this noise possibly? The bolt(s) (broken) loose and rattling possibly. I am going to schedule an appointment with Porsche dealer to check this issue.
No update, unfortunately. We have since sold the vehicle (not due to this) and purchased a X3M40i. Funny you comment this as I just had another member send me a PM asking about this. He had a brand new Macan and same noise. I chalk it up to being normal, but I found it quite annoying. I did replace the diverted valves on both sides as I was curious if that was the issue. It didn‘t change at all. I wish I had a solution, but was never able to get a defined answer.I don’t suppose there is an update on this noise?
It’s so high-pitched that I wince when hearing it. Mostly from the driver’s side. I suspect that not everybody hears this frequency loud and clear due to age-related hearing loss. It really kills the windows-down driving experience for me.
Also have owned and driven many turbo cars. Normally they have a turbo whine or air rush sound.
