I don't know about 735i's, but E30s from the same era will store a trouble
code in the ecu (whenever the check engine light comes on, a trouble code is
generated and stored).. using a code reader (like the peake research one) or
using the 'pump the gas pedal 5 times' method (only for later motronic 1.3
ecus) you can retrieve the trouble code.

See jim conforti's website http://bonnevillemotorwerks.com/techtips.html for
info on how what ecu you have and what the codes mean

I wrote a central lock faq for E30/E28 and I'm sure it's the same for E32..
do a websearch for 'e30 central lock faq' and check it out.. basically, your
drivers door lock cylinder is screwed up, or there is a problem with the
wiring harness (big connector which connects door to A pillar).
