Yeah, I didn't get this either until someone posted the solution.
Use your Tesla Login as if you forgot your password. Supposed to be able to change it.
I haven't actually tested it as my 4-digit code is a good one.
Hint: Same as Kanye's! :-)
jjgunn- Read it, laughed and now acknowledged :-)
Please don’t acknowledge/encourage jjgunn more jokes may come :-)
How do i recover my four digit code to deactivate the "Speed Limit Mode" on my Model X mobil app?
You should be able to "reset pin" on your App.
Go into "Controls" - the option should be there under valet mode & then you can turn off speed limit mode.
