Odd e39 tachometer problem!

[gordyshreds]

Tachometer and mpg gauge not working on my 1998 E39 520i. All other gauges and service indicator lights work fine. Any ideas? I have Removed cluster and checked connectors. Checked connectors to ECU. Did a cluster self test and everything inc the tachometer and mpg needes moved the full sweep. Help!?
