I have an old scanner hand held I had a body shop that I deliver paint to they ordered me a BMW MASS AIRFLOW SENSOR I replaced it on Saturday morning I did not disconnect the battery the car idled good so on Sunday morning I went for Gas and the car started to idle erratic and the service light came on so I put the old Sensor back and cleared the codes 1415 the car runs fine just erratic idle when stopped at a light Any Ideas thank you very much for getting back to me I appreciate it anything you can think of that I did wrong 😑

Good morning thank you for reaching back to me I don’t know how to reset the perimeters and adjustments unless it is only to Disconnect the battery for 15 to 30 minutes is that something that I need to do thank you please let me know 🙏

when I put the new sensor in I only cleared the codes with my scanner did I have to disconnect the battery for 15 to 30 minutes so the computer would adjust to the new sensor I don’t know about any adjustments thank you for getting back to me

I have a problem with my 2007 525i erratic idle I scanned the vehicle came up with code 1415 replaced the MAS New from BMW it didn’t work service engine light went light came on I put my old Sensor in no light on just erratic idle need help please. Just frustrated I did have the starter replaced about 2 months ago I was at work and I couldn’t do it myself I think the problem may be there but repair facility refuses to look into it for something they might have been missed thank you
