I have a '98 M3 with an eleven button on-board computer. Very few pixels remain making the display impossible to read. Do I need another on-board computer and if yes, will an 18 button model work?
There's a DIY for fixing your OBC display. I wrote about it in my blog here [url=http://www.bmwe36blog.com/2007/08/19/fixing-your-bmw-obc-on-board-computer-lights-diy/]Fixing Your BMW OBC Lights[/url]. It should help you fix the problem.
About upgrading your OBC to the 18-button model. I think I saw a DIY for that somewhere, but I can't remember where exactly. I think it was on pelican parts.
