How to do BMW 54 injector coding with Foxwell NT520 BMW Scan Tool?

When you setup new fuel injectors on your BMW N54 engine, you are supposed to enter each new injector value into the PCM. Foxwell NT520 BMW Scan Tool can perform this function perfectly. I would like to perform the coding on a 2007 E92 335i, and the procedure will be the same or very similar on most BMW models. You will be able to reset those values quickly and easily by following the procedure outlined below.

1: Switch the ignition on (do not start engine) and plug the scanner into the OBDII port

2: Select “BMW”
3: Select “BMW” again
4: Select “Scan Vin”
5: If the information is correct select “ok”
6: Select “Service”

7: Select “Drive”
8: Select “Motor Electronics”

9: Select “Adjustment Programs”
10: Select “Adjust Injector”
11: Read through the next few pages by selecting “Ok”
12: Select whether a new DME was installed

13: Select “Ok”
14: Select option 1
15: Using the keyboard enter what cylinder for which you would like to enter a new value

16: Using the keyboard enter in the new value for the injector.
Note that the code will be printed on the injector

17: If you wish to enter more values select “yes” and follow steps 15-16, If not select “no”
18: Select “option 2” to save the new values
19: Select “yes”
20: Select “ok” and switch off terminal 15 and terminal R
Terminal R is Key in ignition
Terminal 15 is ignition on
21: Select “ok
22: Select “ok” and switch on terminal 15
23: Click “F1” to end the coding
24: Your new injectors are now coded to the PCM
