I Keep getting this light and I pull over and all the tires have around the same pressure...

I do have a loud humming noise coming from the tires, I can't tell if its a tire problem or something else.

The tpms battery in one of your wheel is going out...

Thank you, Is there anyway to check which one it is? and will the car be fine driving with it on for a while?

If your tires look inflated correctly then you should be fine. I'm not sure if the VAG tool will read which tire is giving the sensor issue, but to get it sorted you may have to pay the 50 bucks and get the dealer to diagnose...

How is the spare tire?
yes you can read which tire is low or what battery is dying in the sensors, if any or all of them tread less than 30 months left replace them all.

All of the tires are 37 lbs... and they are brand new the lady I bought the car put them on before I bought it.

The light only comes on when its super hot out(mid day, I live in south florida to boot) and then it stays on..

How much would Audi charge to get it checked/ replace?

I'm having the same problem. I checked all 4 tires and they had perfect pressure but my tire pressure light is on. we even reset the light and if was off for about a day but then came back on day, just checked them and pressure is fine. What is it? and just to be sure the tire pressure light and the TPMS comes on.

It's quite annoying... I reset it on the computer and then it comes back on within an hour of driving... I looked on all data there is the tpms sending underneath the rear bumper but I don't think that has anything to do with it...

Check your spare tire pressure also. Might just be that.
