1994 BMW 325 Electrical Problem

Greetings:
I have a 1994 325 with an electric. prob. Intermittently, the speedo/tach/fuel/temp gauge will drop to zero while driving. Usually after -20- seconds they will come back on again...everything else in the display module remains working. The schematic shows a BRN/ORG ground wire common to these -4- modules they picks up vehicle gnd under trim panel on passenger side. I have located and cleaned/checked this connection. Have also cleaned/replaced the vehicle gnd strap (near front rght whl). Have removed the speedo cluster and even taken apart the plug going into back of ubit to make sure the gnd wire is connected and seated properly. Problem still exists...I wil run a seperate gnd to replace this wire, but suspect that the gnd problem may be inside the cluster. Has anyone seen this problem and come up with a fix? Can a BMW dealer work on the cluster?Want to maintain mileage accuracy.
Thanks!

All BMW will go for is a new cluster if they are still in production,check the fuses for corrosion and tightness.

According to the Bentley Service Manual, 94' e36 fuse positions.....there are 4, fuse #23-5A , #27-5A, #31-5A, & #46-15A.....also could be a loose connection on the harness in the back of the cluster.

johnny,

I have just had the same problem with my 320, ended up changing my instrument cluster and all is now good. I am also waiting for a interface to turn up to try and change the odometer reading back to original.

I had the same problem on 1994 318is. I just finished installing a used gauge cluster purchased on the internet....like 30 minutes ago. Totally fixed the problem and I am jazzed. However....the mileage is wrong and whoever sent me the gauge apparently had an automatic and mine is a 5 speed so the transmission light is on. I am now attempting to locate the correct plug in the back of my old gauge that stores the mileage and service info.
