Kuan,

The VW system is not quite the same as the MB system, even though they use the same acronym. The VW system as it was explained to me when my daughter was looking into a Jetta TDI does not have a yaw sensor, so it pretty much does not intervene before there is a speed difference between wheels. But I believe it still manipulates each brake individually. It is less clear to me how the VW system is as functional as the MB system. Jim
