Mine failed a few years ago, research led me to the conclusion that they were made of pure unobtanium.
Further research indicated its a simple 12v relay, the only thing special is the case and associated plug and socket.
I did a detailed write up with pictures on how to replace the old Bosche with an off the shelf $5 relay from your local auto parts store.
You will need a soldering iron, some wire, simple tools and patience, but the end result is, no more ABS problems.
Do a search on ABS and my nickname, Crabs.
I cant post a link as my tablet that im using wont let me do a search.

Ps, you will absolutely need a Tech1 to reset the ABS code.
