I have had the same problem, they are silver anodized aluminum sleeve nuts that hold the TPM to the inside of the wheel. I had a white knuckle moment when the nut split and I experienced a sudden pressure loss in the front left tire at 100 kph! Don't these German engineers know salt and aluminum don't mix! These nuts are available as a replacement part so if there is not too much corrosion to the TPM stem they can be replaced, use generous quantities of antiseize on reassembly!
