High Beam Issue

An FRM comes with nothing substantial on it. A new FRM provides for basic operation at that point. After physical installation, the vehicle order is loaded to the FRM. Most of the E70 equipment is identical so a used one can work as it did here. I'd be surprised, however, if you find some features or indications that aren't quite right down the road. Unless you got really lucky. I'd be interested to see if there are any diagnostic codes stored at this point.

Well so far no anomalies. However I found out this evening that it did NOT fix my high beam issues. I guess I did not drive long enough to overheat whatever is causing my high beam problem.

Any idea what to look at next?

No. I haven't looked at the schematics. I'd look for something that ties the two headlights together, starting at the headlights, and work back. Does your X5 have HBA?

What's HBA?
