Option B is worth a shot if you have The Boys from South of the Border but don't have easy access to a tool to read the ABS codes since in many, many cases the shuttle valve switch circuit is the problem. Look at it this way; Option B is inexpensive, relatively easy and doesn't take much of an investment in time, and even if the SVS circuit wasn't the problem if you've done Option B correctly it will never be the problem. Kind of like preventive maintenance.
That being said, now that you've done Option B and it didn't work you will need to get the ABS codes read. There are several faults that trigger the Three Amigos and aside from Option B you're only guessing without the codes. The next most likely is a wheel speed sensor fault but without the codes you don't know which of the four.

Yep I don’t consider Option B a mod, but a repair to bypass the weak internal connection inside the WABCO unit. I do it on any D2 I get my hands on, then I sort out the sensors and bingo no more 3 Amigo’s that affect so many D2’s.
