Good day Forum:
I am requesting some help with my OBC computer please. My car is a 1988 635CSI, and I repaired the OBC over the winter by installing a new backlite
in the unit. I was very pleased to see it fire up and is functioning in all modes EXCEPT for the Range and the MPG and AVG MPH mode. RANGE and MPG read "----" and AVG MPH reads 0.

My speedometer, odometer, cruise, and fuel gauge are all functioning properly.

I am wondering if anyone else has had this issue before and if so how did you fix it?

Any help or suggestions greatly appreciated.

Thanks

Karl
