And hey, I'm now reminded of how that reprogramming may have already avoided a problem ...

Earlier this year, on a rare (for here) 100*F summer day, my daughter was driving the X5, waiting for 20 minutes in the drive through line at In-n-Out Burger (something I would never ever do), with the AC on. Later diagnosis confirmed that my Aux fan had failed. But the first clue was that she luckily noticed the temp gauge very quickly head up to the hot zone. She then immediately turned off the AC and it went back down to normal temp.

So the difference between 125*C (standard setting) and 115*C (my custom setting) may have avoided an overheating problem. At the least, it very quickly pointed to a problem with the aux fan. I'll look to get the UEBERTEMP programmed as well if I ever get my PASoft BMW Scanner software working again (worked easily and perfectly out of the box, and for a few years, then it seems it is now being blocked by a windows update).

Highly recommended modification, for anyone who has not yet done it. I believe there is some risk when manually editing the HEX values. But if it is a simple checkbox selection as @zboost shows, that should reduce the barrier to entry so more people can get it done.
