Probably.

I EVEN TOLD YOU YOU WERE LOOKING AT AN ILLUSTRATION OF AN X-DRIVE E60 SUSPENSION and you still draw the same incorrect conclusions.
The wheel speed sensors used at the rear of a 2-wheel drive E-8/9X are the type shown in Figure A of the illustration contained in your link. Whether you choose to believe it or not, the fact remains it's a simple square pulse.
Illustration vs. 128i:

The 135i rear pulse ring is integral the the bearing a previously discussed. I wish I'd taken photos of the destroyed bearings from my hub swap, but I don't think that would sway you.
Disconnect the rear wheel speed sensor(s) on your 128i and scope the signal generated by spinning the rear wheels. Try a few 135is.
Come back again and tell me I'm "out of my element" and "don't even know" what you're saying. Post the scope traces. I'll wait.

Incorrect. BMW TIS says you're wrong. I accidentally linked a later DSC module but the E82 is the same type of sensor and I linked the correct one. Read and stop being such an arrogant ass.
Why are you still going on about the sensor targets? I'm well aware of the variants in the 128i and 135i. The 128i uses simple ferrous targets and the sensor is back biased with a rare earth magnet to generate the field. On the rear of the 135i the bearing race is magnetized thus there is no magnet in the sensor. They both generate similar magnetic flux in the sensor elements. The ASIC processes the flux reading from 3 elements and does some basic math and a few algorithms and decides when to output a pulse and the following data (per TIS).
Unfortunately no Oscope anymore since I don't work for the sensor manufacturer anymore. But again, BMW TIS says you're wrong unless it's just disorganized and not going to the right pages or the TIS itself is wrong. The MK60 DSC uses these advanced speed sensors. The Z4 apparently uses the regular simple square wave sensors.

LOL I even found a similar Infineon product. A slightly older version of this is probably in our wheel speed sensors.

These things are seriously impressive.
