How does one access the information module (computer display) in a 1989 325 iS? I removed the radio, but found the neighboring display module was fastened from behind, and I couldn't get to the fasteners. I need to remove it in order to replace the LED, since the only thing wrong with it is that the illuminated display doesn't illuminate. Thanks.

P 124-126 of the book BMW Enthusiast's Companion goes into the procedure in detail. Remove the radio. The light is actually a small printed circuit board with 2 bulbs soldered into it in series. If you are resourceful enough you can solder in 2 new bulbs (if you can find suitable replacements) otherwise you are looking at a $20+ item after the Club discount from the dealer. The bulb slides in from the right side and is flush with the surface. The center panel section has to be removed. There are 2 #1 Phillips screws at the top behind the hazard flasher switch, which you have to pull out and leave dangling by the wires. The 2 #2 Phillips screws at the bottom are harder to reach- you need a short screwdriver. Once the four screws are out you can pull the center console out enough to access the computer. Be careful not to snap off the plastic edges. Then slide the panel to the right as you pull to free the lip on the left side. Note that everything (heater controls, radio balance control etc ) is still connected to the center console. This makes it a little harder to maneuver but it is a lot less work in the end. If your wrist is small enough you can reach in thru the radio opening and loosen the 2 Phillips screws that hold the left side of the computer. You don't have to remove the screws just loosen them. If you cannot fit thru the radio opening you'll have to remove the glove box and side panels to reach the screws from behind. Now with the left side loose you just need to pull the right side of the center panel out about 2 inches until you can access the left side screws. At this point you can see the flush mounted bulb holder. The center panel cutout blocks access to the slide out bulb holder. That is why you have to remove the 2 screws holding the left side of the computer. To get a screwdriver on these you would have to pull the center panel out at least 4 or 5 inches. Open it enough to get a pair of small needle nose vise grips on the heads of the of the screws. Now the on board computer can be pushed in from the center panel, the bulbholder pulled out and the new one slips right in. Maybe there is a different way but what I posted here is what is in the book from the person who did the job. Good luck.
