Finding rattle
Hello all. I have a 2017 GS Coupe and recently I have the most annoying rattle coming from the area of the passenger side rear wheel area. Not a tire or wheel rattle but and interior around the well type rattle. What's the best way to diagnose or track it down? Thank you.

Took the wife's Audi in for a rattle behind the dash and the tech turned me on to an awesome method for finding rattles. He pointed me to an audio tone generator app for my iPad and once installed you play the tone generator at very high volume through the stereo. It's called Tone Gen Pro and it's free. You can adjust the frequency using a slider control or a scroll wheel function. Basically, you position yourself near the problem area, start blasting the tone generator through your stereo, and adjust the frequency slowly up or down until you find the frequency that causes the rattle you've been hearing. Works very well to identify rattles in a car.
This is the one I used from the app store on my iPad. Haven't looked for Android but there should be something similar.

Now, be advised that you're going to hear all sorts of rattles when you do this. Your car may sounds like it's going to fall apart. You have to let those slide and focus on the ones that you hear as your driving. The tone generator is going to turn up rattles that you won't hear on the road so there's no since chasing them.
Hope this helps,
Mike

Good luck finding the rattle. They can be a real PITA to track down.
