EEP-2 Dash Error MESSAGE!!! HELP!!! (E36)

Help!!! Have an '97 318IS with what was intermittent, but is now a permanent problem. Message eep-2 (not eep-1) message is displayed where
mileage should be...AND, the fuel, temp, speedo and tach gauges are all "dead".
The problem began in the summer, but when the car warmed up, and ignition switch cycled the message went away and all of the gauges worked. It's been unresponsive for the last month, and the hope was it'd "fix itself" luck.
Does anyone know what the problem might be. Any ideas/suggestions greatly appreciated!!!
