@Jurgens, my experience with such AR part is not very promising:
such part results in a major difference in the calculated slip (front wheel speed vs rear wheel) and as such the DTC receives a "wrong signal".
I have done some test rides with the AR part vs the orig ABS block, logged the data and send the data to AR. Result: after a lot of lip promises, no action by AR.
So my recommendation: just buy the cover plate and save your money to go to the gym to cope with the few more grams of the cover plate solution.
If you need more details, send me a PN.
Once a decision has been done, never explain, never apologize.
