I don't know if it is safe to remove, but my 100, S4, A6, S6 ('92-'98)
says this about a unit installed between the left rear and right rear
brake calipers:
"The brake pressure limiter, installed between left and right rear brake
calipers, is a delay-dependent brake proportioning valve that prevents
locking of the right rear wheel when simultaneously driving rapidly
around curves to the right, and braking."
It also has adjustment and operation checks.
Sounds like your unit. Why there isn't one for the left wheel for left
turns, it doesn't say. My not very educated guess is that left turns in
the US aren't as tight as right turns and therefore don't need wheel
lockup prevention.
