Title: mpg readings wacky
Post by: ///m42 sport on November 10, 2008, 06:07:16 PM

I noticed that my mpg gauge moves but the needle stays at 7mpg no matter how light on the gas I'm at.  Is this a mechanical or electrical problem?

I imagine electrical since E30's seem to have issues with gauges.  Seems as though the first thing to do is pull out the gauges, check the connection and re-sodder, then replace to dash and see if it works.

Well it seems to have fixed itself.  :)

More often than not if any of the gauges start acting up, just smack the dash just above the cluster and that should fix it

Well I changed my 02 sensor today and the mpg gauge seems to work correctly now.
