Replaced bomb - still a problem?

["Jim Haseltine" <Jim@ur-q.freeserve.co.uk>]

Replaced the bomb on my 88 Ur-quattro this morning, the old one
depressurized in 4-5 pumps, the new one in 40-50. I was shocked by the
colour (and debris content) of the fluid that drained out of the brake line.
Big improvement in the brakes, but if I leave the car for a couple of hours
the new bomb seems to depressurize 'cos when I start the engine I'm seeing
the warning light, sometimes flickering, sometimes on constantly. Once the
engine has been running it goes out and stays out.

Any ideas?
