Just over 550 miles and the first time i heard the warble sound at around 50 mph in my new 2019 C7 A8. Only did it 3 or 4 times. I hope this don't mean days at a dealer with no parts. Otherwise the car has been running fine.

Have not heard it the last two days. Odd it just popped up one day so far. It was loud the first time i heard it and sounded like a slap slap slap sound. 3 other times on the same day it was no where near as loud.

Seems to be the gears in the rear end. I'm just gonna drive it and not worry about it.

A8 auto with under 600 miles. Do a search for warble sound on C7 Vette and you can see the vids and hear the sound. I only heard it Sunday and not any this week.

Same thing today. Everytime i got to 1500-1600 rpms i would hear it when getting on the gas a little bit. Always at 1500-1600 rpm's

I will take it to the dealer when i feel like dealing with them. No mods for a while until this is worked out.

At that point, the engine typically switches from V8 to V4.

I'm betting your AFM (Alternate Fuel Management) feature is kicking in like previously mentioned. When dropping back into the V4 mode, it sounds like a phart pipe to me. There is a way to disable or you can run in manual all the time.

I think you're right. Mine had it at 1500 RPM's, and a Corvette tech told me it was harmonics originating from the exhaust. It disappeared when I swapped out the factory X pipe for a Borla X pipe, not to say this would work for others.
