Hey team, after having a few drama's with my abs system and my dealer having other ideas about how things should be fixed i went ahead and researched the pins after being given a tip from Bradtot. Big hand to Dicovery Automotive in Perth who helped me out, they were reluctant to part with any (they only had a few left) but were most forthcoming with where to get them.

Anyway the part number for the pins is 927777-3 and AMG distributors in melbourne and queensland sell them for 35c + gst each min 10 per order. They are quite happy to sell to general public and send things off in post bags.
