Some Speedo Trouble

[sdenali21]

I have a 97 318ti and am having some speedometer problems. When I first start the car, it usually takes the speedometer at least 15 or so minutes to start working. The gas guage also seems to fail as well. The speedo problem is also a hassle as it controls some many various other systems (ie cruise control, wiper speed, etc). I have tried taking the car to a mechanic, but they were unable to find the problem. Anyone else have any ideas what this could be?

Thanks for any ideas

Could be a faulty ground, in that more than one item is malfunctioning. The ground could be similated by placing a ground to the circuit board of the inst. panel. It is easy to get to if you have a rubber neck. Just have to stretch a bit.
Before you go thru this, look for fuses that may be corroded (doubtful tho), but the idea is that you do not have a good elect. circuit....either ground or otherwise.
