I see cyl #3 also index 8. What if I can only get index 09 . Can I buy just 1 injector and install in Cylinder 4? That meanYes, 08 means index 8. I would check all of the other injectors index numbers. You should be able to see and photo w/o removing. If the others are not all 8's, then maybe you can buy a replacement and rearrange to make them the same on a given bank. I'm surprised to see index 8 injectors. In the US, BMW had a recall campaign to install index 9 injectors. 581 & 227 below the bar code in the second photo are the calibration values that need to be entered into the DME. There is only one pre-cat O2 sensor for each bank, so it's important that each injector supply the exact same amount of fuel for a given opening duration. The codes allow this to happen.
What was the recall of injector . Wonder if I can still get from dealer for replacement of injectors.
Thanks for your help with the calibration value . I have no idea when people are talking about calibration value until now.
