i have new batteries in my si board but tach is not working and speedometer wont light up even though i have new bulbs. this cluster is pissing me off. where does the tach take its reading from, maybe something at the other end isnt right? its an 84 318i.

did you check the plug in the diff. pull it out and make sure its not corroded

if the speedo does not light up

play with the white plug on the rear of the cluster.

ya that would be the same suggestion I would have. My cluster started getting wacky on my 86 325es, and I just had to adjust some of the wires in the back because they were a little corroded.

I have no clue if that is how you spell corroded?

pretty sure the dealer is the only place to get those bulbs.

they pull out of the little holder. vw guy had some they are out of the bannana marker lights on mk2s
but i got new bulbs and they dont work .. so im guessing my cluster is kaputt

the speedo just bounces around on and off sometimes i look and its on and sometimes i look and its off
pretty homo

i checked that . its retarded. i got my lights and everythgn working and just the speedo decides if it wants to work or not
ive checked pretty much everything that could be checked besides the si board batteries. but i cant see it being that since it works perfectly when it does work. and when it isnt i hit a bump and it turns on sometimes . finicky piece of ass
