TPMS vs. DSC

I know in E92's starting in the 2007 MY, they used the TPMS in the wheels. In 2006 E90's, they used the DSC system to detect a change in the RPM's of each wheel.

When did the E90's start using TPMS? Was it in the start of the 2007 MY, or was it later in production? (March production brought about a few changes IIRC)

Some 2007 models have them. For 2008, all US model Non-M, 3 series cars have TPMS sensors.
