Once in a while, in my 1992 735i, the OBC computer doesn't come on when I turn
the car on.
At first I thought it was the bulbs had burned out -- so I set the max mph alert
Today; it failed to come on -- and; I went to 35, 40, 70 -- and no alarm.
On one (of about a dozen times) "ignition on" the OBC powered up. Clock was a
few minutes slow.
I checked the fuses (replaced them actually) still -- same symptoms. This is
not "every day" just "once in a while" and when it happens, I can turn the
ignition on & off 30 times w/o it coming on.
Everything else works fine; so it appears something specific to the OBC -- Could
it be the OBC or some connection to it?
