There is also a "feature" coded that always turns the AC on and turns off recirculate regardless of the last setting when the vehicle was turned off.

If it bothers anyone that much, the best solution is to google NCS Expert, NCS Dummy, buy a cable, and code it off. It is not a Car/Key Memory programmable feature, so the dealer will be of no help.

hmmm gotta look into this a bit, and am a bit of novice but want to code this out ...@iansanderson was it difficult to do ?

Bump. Has anyone ever resolved this? I took a look at the coding options for IHKA on NCSExpert and haven’t seen anything that could be disabled.

For anyone who's had to replace a worn/broken blower motor, this auto-on fan thing is annoying. I don't want to ever have to do that job again, so I manually turn off the fan every time I start my X5. Has coding been successful for anyone?

Never running the fan is not likely to result in the desired outcome. If you bought a quality part it will run the remaining life of that car even if running half speed. Not running will likely cause problems with the bearings that will generate crazy amounts of noise when you actually need the fan. You will port yourself through plenty of discomfort that m you went through significant effort to avoid by replacing the blower. You fixed it: use it.

All that said one of the first things I coded on our E70s was to not turn the AC on every time I hit the auto button and to leave the circulation where I left it. (that bit me though when I accidentally switched to recirc only and left it for a week or more before I figured out why my ventilation sucked)
