P3D+ Sheet metal pop sound

Someone on the Tesla forum just took his car in for service and asked about the noise and they were totally clueless. Had no idea what he was talking about.
Intermittent clunk while driving, very distracting and worrisome. You can feel it very strongly in the floorboards. It does not seem to come from one location. We are 3D, vin, 66278, took delivery 9-15-18.
After 2,800 miles on my P3D+ this happened to me for the first time yesterday. Once while parked after a ~30min drive, and again while supercharging. This is also my first time driving in temps below 80F, so I think it is definitely correlated with some type of thermal expansion.
The "clunks" people are referring to when starting to charge or during software updates is normal when the contactors are engaging. This noise was much louder and I definitely felt it in my feet through the floor.

I’m about 100% on thermal expansion. Tesla service is still unaware based on an unrelated visit yesterday.
I've experienced the sound/feeling that's being talked about in this thread, however I'm experiencing other "vibrations" that can be felt in the accelerator pedal on my P3D+. Anyone else experiencing weird feelings/sensations/vibrations on the accelerator pedal? It doesn't always do it, and it's not tied to any particular road. Originally I thought it was only happening on bumpy/poorly paved roads, but it's not linked to that. Almost feels like some type of rubbing / vibration sensation against the bottom part of the accelerator pedal (at any speed).

It’s not a diagnostic issue—it’s whether there’s an easy fix. The frame can not be moved with the battery removed because the frame isn’t as robust as previous models.
Hum, if they keep it on a flat surface, seems like it could be rolled (but might not need to be).
Fix might be as simple as: drop the pack, add a piece of foam/ rubber to preload the two surfaces, raise the pack back up.

They routinely roll S and Xes around, but are currently prohibited from doing that with the 3s. It may require some sort of jig to prevent flexing or torquing the frame if they do need to move it. I wonder if this noise relates to the flufferbot firing

I had that thought of injecting an expanding foam—curious to see schematics. Hope it would not create a mess if the battery were ever accessed. It seems the rear floor may have plate that in common.
The pack (specifically the penthouse) is the 'floor' under the rear seat. The foam is a cool idea if it has super low adhesion or is done inside a pouch to prevent gluing the pack to the chassis.
I've heard it at least half a dozen times. It scares the bejeezus out of my wife but doesn't really bother me. I always assumed it was the battery cooler damper up front either opening or closing. But after viewing the part schematic, I don't think it is a damper:

I have a dual motor non performance I picked up early September and noticed a series of thunking noises when I was supercharging two days ago. After driving over 100 miles at 80 MPH and arriving home it thunked about 4-5 times in the first 5 minutes I was there. I started charging and went inside so who knows when it stopped. I have around 3,500 miles on the car and never noticed this before.
