Not sure if this has been posted - but had a question and someone had posted it in another forum.
Our iDrive screens have auto-dim controls - just like iPhones, etc. If you ever are driving in overcast weather or a garage, you might notice the brighness level isn't quite 100%.
To adjust brightness manually, and turn off the auto settings, go to this module in Expert Mode:
HU_NBT2 - 3005 Display PIP Info - DIM_VARIANT
And once in that module:
- Value will be set to NEW
- Simply change the value to OLD
The "old" will change the iDrive display menu setting for brightness in day - AND night. The "new" setting only allows you to change the brightness level at night (when you navigate to the setting now, it says "brightness at night" or something like that).
This makes a BIG difference during the daytime - no more washed out, dimmed iDrive screen. Just make sure you turn brightness to 100% in iDrive display settings (it defaults to 50% after you code).
