How difficult is it to remove this board and will I be able to drive without it. (I'm think I can but want to know definitely!)
It's a small board perpendicular to the instrument cluster's board, soldered to the cluster by four standoff pins. Should be fairly easy to remove, and the car will run well without it. If you jumpered between the AUSG. and GEBER holes you'd still have the light hooked straight to the sensor. (The legends are etched into the foil side of the little PCB.)
If so, I'll pay for shipping and you can repair it as a guinea pig.
I anticipate a low likelihood of repair, mostly I just want to see how a dead one behaves on the bench. I really don't want to try to induce suspected failure modes on the good one that's supposed to be in my car! -- Jim
