Hi All

New boy on the block. I have been through the forum but can not find any additional info so here goes hoping someone can help.

1993 E34 530i RHD 191k km's. Warning display for Brake, tail, number plate and dip light comes on when I switch on the head lights and won't go away until I switch the lights off then turn ignition off (short delay before the warnings shut down). No warning during the day (lights off of course).

I have read the info re the LKM and as an experienced electronics tech I can confirm I have re soldered all the relays (4 relay LKM) and LKM connector joints. I have also re soldered a number of through board holes and components (using hot air gun).

Absolutely no change. Problem persists. All the lights work correctly at all times.

Does anyone have any idea's?
