Hmmm. I don't have any experience with these yet.
I own the same car as you but this is my 1st BMW.
Some Mercedes Benz vehicles use the wheel bearing as the reluctor
for the speed sensor. One end of the bearing has a magnet in it.
Therefore it can be installed backward, causing your problem.
I really have no idea from here.
Hopefully someone with some experience will chime in.
I'm sorry I can't help more.
