Hi guys, so my car had, as most e34s do, the problem with the capacitors.
My speedo would go out, my fuel tank indicator would indicate random levels, and the backlights of the LCD displays wouldnt work intermitently (the LCD did work just fine, you can see them with reflection from the sun or any other light source).
I changed the 5 damned caps, and now everything is working ... except for the freakin LCD backlights. They still go out every now and then. Im not 100% sure, but i would swear its more prone to doing it on cold and humid days/nights. During summer it seemed to be working mostly all the time. Now that summer is over, and its starting to get cold at nights, its getting worse.
I changed the instrument cluster dimmer, since the original one was not working correctly along the whole path.
All the light bulbs on the cluster are new.
I get perfect ilumination for all the cluster, dimmer works just fine, all dials work as they are supposed to. But some days, the backlights of all the LCD displays, just go off. And maybe after driving for a while, they just go on again.
When swapping the caps, i checked to be sure there was no damage to the PCB, no rust. I cleaned the contacts where the light bulbs plug.
Im out of ideas, any clue how to fix this?
Its annoying since i cant see in what position is my trans selector. I need to go to P and start going down again.
Thanks for your help.
