Does a wheel size change require re-code?

I'm upgrading from 19" to 20" wheels. In order to ensure speedometer accuracy, do I need to have the dealer recode the X5? Should I even worry about it since the change isn't that significant?

No need to re-code because when you upgrade the wheels to bigger diameter you use low profile tires and that compensates the difference.
