At least my X5 has sensor in the wheels, which means it is TPM and not FTM. BUT, it doesnt have antenna for each wheel sensor. As long it have received signals from 4 wheel sensors it is satisfied. It doesnt know from which wheel each signal comes. It tells me if there is a pressure loss, but doesnt specify which wheel and the actual pressure and temp. This is like to to go to Rome and not see the Pope
