DIS v44: Diesel Injector Coding / Programming Guide

If an injector is replaced it needs coding to the ECU. Once you know what to do, injector coding is a pretty quick and easy job, all 6 can be done in about 15-20 minutes. You will need a working install of DIS and EDIABAS, so a download and setup-guide is in this post. The code is 6 or 7 digits and printed on the top of each injector, more information in this post.


** Connect a float-charger to the battery before coding with DIS ** The process takes 10-20 minutes if all goes well, but it is not worth the risk of doing adjustments to the ECU without one.

1. Connect car to DIS and perform API test.
2. Click on 'Diagnosis'.
3. Select 'Series' and 'Model series', then click the forward arrow.
4. Click on 'Yes' to start the 'Short-test', wait a few minutes for it to complete and click the forward arrow.


5. Click on 'Function Selection'. (Bottom left.)
6. Select 'Service Functions'.
7. Select 'Drive'.
8. At EGS transmission control prompt, select 'No' if your car is manual, 'Yes' if automatic, and click OK.
9. Select 'Diesel Electronics'.
10. Select 'Adjustment Programs'.
11. Select 'Injector rate adjustment' so it is highlighted in black.
12. Click on 'Test Plan'. (Bottom centre.)


13. Check 'Injector rate adjustment Bxxxx_Dxxxxxx' is highlighted and click the forward arrow.


14. Wait for the fault memory to be read and at the 'Fault codes are stored...' prompt click the forward arrow.
15. Wait for the current calibration values to come up and click the forward arrow.


16. Select '1' (Enter new calibration values) and click the forward arrow.
17. Enter the number of the injector into the keypad to be re-calibrated and click the forward arrow.
18. Enter the new injector code into the keypad with no spaces and click the forward arrow.


19. If more than one injector needs coding, select 'Yes' to the prompt and click the forward arrow, then repeat the last 2 steps for each injector number. If not, select 'No' and click the forward arrow.
20. Select '2' (Save calibration values) and click the forward arrow.
21. Check the values are correct, select 'Yes' and click the forward arrow.


22. When the new values are displayed click the forward arrow.


23. Select '3' (End) and click the forward arrow.
24. When 'End service function' is displayed click the forward arrow.
