Flapping noise at high speeds

[ARoach04]

Hey All,
Jumping over here from the B8.5 S4 forum with a question about my wifes 2015 Q5 Prestige. When driving her car at any speed above 80mph there is a flapping sound coming from under the drivers side rear seat. When sitting in this seat, I can feel the flapping coming from under the floor, I think it might be one of the soft covers from under the body. Anyone else have this problem and able to resolve it?

That's what it sounds like to me. Have you even looked yet?

I would recommend looking and seeing if you see anything.

Yes I've looked. I had the car up on the lift last weekend but nothing stood out. I can't see under the car at 80mph, so I was wondering if this was common issue or not.

I would recommend looking and seeing if you see anything.

Thanks!

Aahhhh.... That makes sense.

Do you have a roof rack or anything that's been added? Sometimes added items can make weird wind noises.

Have you inspected the tire(s) to see if maybe there's a cut piece of tire that's coming lose at that speed?

I would also check to see if the exhaust is firmly in place.

Additionally check the rear license plate to ensure its securely mounted.

I had the same noise with only a few hundred miles on the car and it ended up being the lower rear valance flap that's attached to the spare tire well under the car. It's worth a shot. You'll know what I'm talking about ounce you look underneath.
