you probably need a new master unit, inside there are 4 seals and a bakelite ring, the seals could be leaking, I posted here a disassembled brake master unit https://www.bimmerforums.com/forum/s...=bakelite+ring
Shogun tricks and tips for the E32 series are HERE!
Sounds like you have introduced air into the braking system and low pressure may be triggering the warning light. Bleeding the brakes may well cause the light to go out. This thread explains how to bleed the system on the E32 but I am pretty sure that the E34 works in the same way:

Note that some parts of the system work at extremely high pressure so be very careful
OBD2 scanners do not work on the E34. It uses a system called ADS. But if you resolve the problem, you may not need a scanner at all
