OBC Help Please
i have a 93 BMW 325I and im having trouble with my 18 Button OBC.
When i turn the car on, the button lights come on but nothing shows up on the screen. I have checked the bulbs & have seen that its missing 2 of the 4 required. If only 2 are working would it show anything? Is there a hidden fuse? or do i need to fix the pixels?
Thanks for your help in advance,
