Tire-related issue or transmission?
For months I have been trying to find a solution for a helicopter-like noise when accelerating in my 2006 Cooper base automatic with 35k. I bought the car last year with 29k and have only gone about 5k.
The noise is only when in drive and accelerating. It disappears when in reverse, neutral, and idle.
In June, I drove my Cooper going 25mph when I hit a bad pothole. This seemed fine at the time, but when I arrived home the helicopter noise suddenly appeared. Ever since then I have not gone more 500 miles and have just been searching for an answer.
We were told it was the transmission. We had the 30k transmission service done recently, and have brought it to be checked all over, but really have not driven the car since. I just really can't afford to keep bringing it places with no answers, so at this point I'm just looking for a miracle.
As for if it is a tire-related issue, the noise only occurs when accelerating and seems loudest at 10mph - 15mph. But, the noise does stay, as it can be heard at 50mph and below. Also, the brakes produce a lot of brake dust and the tires have not been rotated in the past 5k.
And in my research, some have said they had a helicopter noise that was related to tires/wheel bearings/alignment.
At this point I am just trying to stay optimistic, because the only other option is to replace the transmission, which will cost the same amount as I paid for the car. Since it only has 35k miles I am trying to do everything to keep it. Any ideas?
Heres a video of the sound:

I brought it to 3 places, and there wasn't a thought to check the tires. I figured it was engine related and didn't think to check the tires after all this time. One person said transmission and since then I haven't driven it.

With hitting potholes, it could be as simple as the wheel weights jarred loose - to the point of falling off. That would cause the noise you're describing - especially louder and softer in different speed ranges; consistent with a tire/wheel combo that's out of balance, in your instance, due to the potential absence of wheel weights.
As suggested, get your MINI to a reputable tire shop, as they can re-balance your tires as part of checking this out.

- bent rim from the pothole you hit
- worn out drive shaft(s)
- damaged tire from the pothole you hit
- wheel bearing
Of all these, drive shaft(s) can be more challenging to determine as a lot of mechanics are morons.

From what you wrote, you are not exactly the home mechanic type. I would agree you best bet right now is to take it to a trustworthy tire place, or wheel alignment place. The last place you want to go is auto garages. It is next to no chance your problem is the auto transmission. My best guess based on so little you provided are:

I'd start with a place that just does tires, and have them re-balance all four tires. They'll get a good look at your wheels at that time and will be able to tell you if there's wheel or tire damage. If the wheels are good and all they do is a re-balance, take it for a ride and see if your problem has been resolved. If not, the next step would be to bring it to an alignment shop and have them take a look at it...

Bubble on tire or broken cord in the tire is my guess. Also the side of the wheel could be bent.

Since most alignment shops are setup to mount and balance tires, I'd skip the dedicated tire shop altogether and suggest you bring the car straight to an alignment shop. A tech will drive the car, hear the noise, pop it up on a lift and know straight off what to look for, provided it's a tire/bearing/suspension issue...
Let us know what happens.

Can the OP clarify if this "auto" is CVT, or traditional automatic transmission. I am not familiar with CVT but know it has the infinite ratio driving belt system that I wondered as a child why not used on cars.
I would not rule out it's the tranny if CVT.
In the last video, the noise is so loud and mechanical so does not seem like tire or wheel, especially as low speed. Being so pronounce any mechanic with a pulse should be able to narrow down where it comes from.

if a tire is that out of balance shouldn't the steering wheel vibrate at least a little bit with the noise? I have thrown a few poorly tacked on (double sided tape) wheel weights and the steering wheel and car shook in unison. Do not recall a sound accompanying the shake.
So I guess, does the steering wheel shake/vibrate in unison with the noise?
