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?

We just purchased a 2022 Macan 2.0 with 45K miles and have noticed the same thing. A droning noise (low frequency) between 1200 and 1500 rpm with light throttle (engine load). As a previous NVH (Noise, Vibration, Harshness) engineer I have encountered this on many vehicle platforms. Typical culprits are structure borne resonance (engine order related) through engine mounts or exhaust hangers/attachments. This type of structural vibration input sets up a standing acoustic wave within the cabin. I plan to alter the dynamic behavior of the exhaust system (add mass) to see if there is a change. The other possibility is an acoustic resonance in the exhaust system. I'll repost if I am able to solve. The sound quality at low rpm is very annoying.

This will sound crazy. I have a 2020 base and routinely drive from my home in Evergreen Colorado at 7400 feet to my other home in Ohio. I notice the same droning noise whenever I get to Ohio. It happens at low rpms such as when I am stopped at idle. I eventually get used to it but it happens every time. It does not happen at altitude. I will follow your thread to see if you can solve the problem. I just gave up and attributed to exhaust system resonance and weird air pressure interaction.

Place it into sport mode to drop a gear and get it into higher rpms, you don't want the engine lugging at that low rpm.

The sound is likely due to the potential for low speed pre-ignition and adjustments the ECU is making to timing and fueling to avoid it, as mentioned in post 4.

Thanks for the input. I routinely drive in sport mode once I hit 150 degrees. No change. It's just something I have gotten used to while in Ohio. Oh, well...
