We don't have a tire pressure monitoring system on the E53. As tmv states above, we have a tire diameter monitoring system. They are taking your money. The only "rebuild" needed is for your wallet.

Replace the valve stems, mount, air up, balance, install, torque, push/hold tire monitor button, drive. No rebuild step.
