I don't buy that at all. The factory fill is Pentosin FFL-4 (called BMW DCTF-1), which is exactly what they sell at the parts counter in case a DCT gets replaced. Why would BMW intentionally offer an inferior product at the parts counter?
There are several aftermarket fluids that meet DCTF-1, by the way, meaning they have at least the same performance as the OEM fluid if not better.
