under youe e brk handle ther is a reset button. air pressures should be at least 34lbs. did they reinstall tire pressure monitors in new wheels?
Pressed the resest button then the indicator turned from red to orange don't know about the pressure monitors as I bought them from the internet they are 17" john cooper works wheels is it worth trying to put 34psi in them.
