Intermittent Error message - PPPPPPP - displayed on dash

1993 BMW 318i
3 days ago I started my car and a problem: 'PPPPPPP' showed on the dash, and the tachometer, temp gauge and fuel gage weren't working
Also when I drove away a beeping sound started and continued until I either stopped the car or turned my signal lite on. Beeping sound would start again when I started a turn.
Next morning I started the car and everything appeared to be normal.
Hour later after parking the car and than restarting, the same problem appeared again.
Intermittent problem continues.
HELP: Does anyone recognize the problem/solution? Any suggestions.
Thank you
