Is there one? I don't think there's anything in the plumbing between the master cylinder and the calipers, other than a simple brass T-piece by the fuel tank.

Hmmm, according to RealOEM there is such a thing, but I don't remember seeing one on my touring. Seems like you've answered your own question.

As for the leak, are you sure it is that thing, not the master cylinder leaking down the brake pipe?

Pressure regulator is on the bulkhead in the engine bay, just a few inches from the brake master cylinder.

iv checked all the pipes and the mastet cylinder and they are dry, the only thing that is wet is the thing below the master cylinder

BMW don't list any individual parts for it, But I expect it's just a copper or alloy washer that you should be able to get from a motor factors. May just need tightening up.
