This is a description of the oil quality sensor that BMW started using in 2005 or 2006 on the N52. Current parts books show the same part number, so I suspect it hasn't changed. Oil additive depletion is calculated via capacitance changes in the oil. It isn't a complete measure of oil quality, but simply one more factor for the DME to add into the distance to change calculation.
