E21, E30General discussion and technical help for 1975-1991 3 series cars.
Hi, I might add, Programa -Website programainc.com offers a rebuilt SI board that i bought for around 120-150 (I forget, it's a year ago) It's built new in a fraction of the board space-plugs right in- with a battery eliminator, my E30 has the led indicator on a slide off module- so when I put it back in I kept the led module off. Viola! A mute SI board with all gauges working perfectly,permanently! Check them out, ALL BMW electronics here!!!
