A while back I was looking for the following:
TBS # 6102933812
issued AUG 93
regarding Emergency Flashers Self-Activate.
I was experiencing hazards that come on without an apparent reason and could not be turned off.
The BMW dealer in my area (Valencia, CA) refused to pass
the techinical info. After not getting any response, I bought the ALLDATA CD containging all TSB for 1993 525i (E34).
The TSB states that prior to 8/93 the crash relay
(brown relay labeled Crash-Alarm-Gerber 12V- 1 384 732)
may have a defective transistor. It recommends
replacing the relay with one built after 8/93. The date
code is stamped on the relay with the year, week, as
the 1st 3 digits. Mine was built in week 46 1992 because the number was 24671.
I am entering this note so it gets archived.
