Never had that problem with my car and I used Dave's wiring chart for VSS.

maybe you need really short gearing to notice it. Or it could be a specific DME coded to a specific ABS module.
It does seem odd that nobody noticed this before. Also I spit out a 9-tooth signal to an MSS54 dme and it read pretty much normal, so I don't really understand why BMW would have done it this way for basically 3 years of E36 production only.

But i have to clear the code because it is still stored. It does happened very often but it happens

for OP-
are you using a E30 speed sensor in the diff or a E36 unit?
there are 2 e30 speed sensor styles and also more than 1 part for e36/e36-7 speed sensor.
the tone ring is smaller for the e36 units and the sensor changed. e28/30/34 all use a larger diameter tone ring than e36OBD1 M54/M52TU swap as a M50b25

.
The circuit works fine, I'd still like to know why some OBD2 cars have this issue and others don't...

The ABS "sees" very high impedance with circuit connected, almost nothing is drained from the ABS so it works normally. The output signal will be a pseudo-VR signal.
What is everyone else with OBD2 doing for the VSS signal???
