I have been having lots of noise and vibrations at high speed. I took to the dealer (VW) and was told it was because of flat spots on my tires. Its a front wheel drive.

My threads are in pretty good condition. They can easily go 10k miles more.

Does the flat spots create any problems elsewhere in the vehicle? Should I replace the tires ASAP?

Also could there be other reasons why this noise and vibrations happen?

Adding a video so everyone will have better idea.. https://www.youtube.com/watch?v=ZjMFzi_xmPk

Firstly discs do not warp.Pads contain metal that deposit on rotor so when measured in a number of places it is assumed the disc is warped.Check balance weights on rim have not fallen off.Jack up front wheels one at a time;grasp tyre each side of centre and pull to and away from you.Any noise or movement may indicate that tension on bearings is incorrect

Thanks, Please check out the video link I attached to the ques. –  Hardy Apr 9 at 18:26

There are a few possible things which could cause vibrations:

  1. When breaking hard, your discs could take up some heat and get warped, great article could be found here.
  2. Bad geometry could cause vibrations + uneven tyre wear (flat spots maybe?), see related article.
  3. Check wheel balancing, article here.

I would recommend to check these first, there are couple more issues but these are the most common, which could possibly fix your problem.

Thanks. I do notice that between 15-20mph (speeding up or down), the vibrations are the most. May be point 2 applies. I don't think there is vibrations while breaking. I had wheel rotation a couple month back. I don't know if it included balancing. But this advice certainly helped. –  Hardy Apr 4 at 17:03
    
Also, can wheel alignment have a case in this. –  Hardy Apr 4 at 17:04
    
Geometry=wheel alignment, yop this could be it, going through potholes/bumps could scatter wheel alignment. –  Mustafa105 Apr 6 at 9:26
