Sensors for wheel speed...once more!

[Psychil]

Once again, here we are.
Before installing the new front right-hand sensor, I cleaned the large plug that connects to the ABS unit and the chassis connector that the sensor wires go into. For approximately twenty miles, everything is OK.
Now I'm experiencing the same issue as previously (ABS warning lights, etc.), and I had a strange sensation when braking, as if the ABS were partially engaged, but it has since gone.
Even when the vehicle is not in motion, the front right wheel speed fluctuates greatly when using iCarsoft to monitor wheel speeds. Its shifting speed can drop from 120 kmph to 0.6! Upon coming to a complete stop, the values of the other wheels become nearly zero and remain constant, while the front right wheel will erratically fluctuate between fifteen, seven, twenty, six, etc., before finally settling on the same number as the others.
Is it the sensor or a faulty connection somewhere? Have you any suggestions?
I am grateful.

Since I did not unplug the sensor from the chassis harness before removing it and the signal remained after turning the wheel, I would presume that the problem is not with the connecting cable. Upon reinsertion, a signal is detected, leading me to believe that the sensor is operational. However, I should probably test it with a different sensor just to rule out the possibility that the original one is producing inaccurate results.

Is the reluctor ring checked?

I recommend using authentic wheel speed sensors if you haven't already. 👍

Carsoft has detected a signal, therefore I am hesitant to confront it quite now. The strange thing is that it occasionally registers such drastically different wheel speeds.

No one, even Mercedes, has ever explained to me why the genuine article is superior. The same folks who make aftermarket parts also make the "original" parts. The components provide the true rationale. Miniature integrated circuits and discrete bits make up a sensor. With a yield of 99%, the majority of components in semiconductor manufacture are within tight specifications, while the remaining few are not. The leftovers are either resold to aftermarket vendors or kept by the "original" maker but marketed under a different name at a lower price.
In most cases, these components that aren't up to code will still work, but they won't hold up as well when exposed to extremes of temperature or voltage.
This issue manifests in all electrical devices. Resistors are available in a wide range of tolerances, with wider ones being less expensive. Some of them sell them instead of throwing them away, like Intel and other major semiconductor manufacturers.
The manufacturing process inherently results in certain components being outside of tolerance, regardless of whether Mercedes has its own facility.

Afterwards, I will step aside and let you handle it. My best wishes. 😏😏
