I am having a problem with the readout on my dash. I have a 1989 735 E32 Auto. The lights for gear selection, warning lights and oddometer glow but I can't read them. This was an intermittent problem but it's all the time now. I've tried changing the checklight module and lighting module but it hasn't made any difference. The main problem is when the 'warning gong' goes off I can't read what it says. Can anyone help.
