Gas gage, RPM, Information screen doesn't work on 1998 BMW 740i

My battery went out on my car because I was told that I left something on. But, I had the battery recharged and now my needle for the gas goes crazy from left to right sometime and sometimes it just does work like my Rpm,the clock or my information screen can hear it but can't c it.

was the car jump started when the battery went out? if you jumped it from a running car, you may have produced a voltage spike that has damaged components in the BMW. also, low battery voltage will do strange things to a car. suggest you have a BMW specialty shop check your battery/charging system FIRST.
