Macan base 2.0T with 70K miles, regular oil change, everything works fine.

I started to notice droning noise between 1200 to 1500 RPM, outside that range the droning noise go away. Has eveyone else experience the same?

Perhaps the butterfly valves on your exhaust aren’t functioning properly.

They should be closed at idle after a couple of minutes.

Thanks buddy, I'll have it checked out by my mechanic..

Actually it's not great for a DFI motor to be in that rpm range due to LSPI (low speed pre ignition) and the engine laboring at low RPM. Hit the sport button.

Thanks for the comments, I usually hit the sport button right after I start the car, but in city driving many times I'm in that RPM range either way...

What butterfly valves?

Thanks for the reference, but I'm seeing mostly folks with S and Turbo models doing this and would be surprised to see this being used on the EA888 engine. If I have time this weekend I'll take a look. I don't see the point other than acoustic cosmetics and I am fairly sure as has been mentioned it robs low end torque. I've had cutbacks before and they don't start to flow until one is well over the speed limit. As far as piped in sound, I can't stand that it is so systemic to the auto industry. When I bought the GTI the first thing I did was deactivate the VW Soundaktor.

These butterfly valves are visible in the tailpipe of my 2020 Macan base. They are unrelated to PSE or any sound symposer that might be installed.

(FTR, I don’t have PSE)

So, reviving an old topic. What was the upshot of this? My 2020 Macon base, newly purchased, is wonderful but it occasionally does have a drone that is very noticeable. Can't really pinpoint when it's there and when it's not. Is there a way to avoid the drone or is that just life?
