I've never seen some one luck up and get the same values on energy. I guess that's better so you won't be confused. The flow values are definitely how I described it though. They were programmed lower than the DME read value which is a dead giveaway. 1.3 is the lowest it reads and I've never seen an injector lower than 2.xx. Also you had 3 that were coded over the max value which is 3. Cylinder 6 looks like it was the only one coded correctly. Either way they do need to be coded correctly and I hope what I've explained helps out.

what you’re saying makes sense. But the values are what’s on the injectors. Can I change the values to read within spec? Or get new injectors? I’m sorry for all the questions. I’m just at a loss and it’s my wife’s commuter that’s been down since April. if I can’t figure it out, the dealer is the next step.

Really. I would double check to see if what you bought were the correct ones

Ok I had to rethink this and something escaped me since I haven't had to deal with this in a while. Do you have an index 11 or 12 injector on cylinder 6 and index 10 or below on cylinders 4 and 5? When you said you updated to 12's was that for all 6? Right now your values do not look like index 12's. Cylinder 6 is the only one indicating it's a 12

number 6 is the only one that I bought from someone else. 1-5 are from the same person. All index 12’s. I’m not doubting(now) that there’s something wrong wrong with 1-5.

A while ago people were selling knock off index 11/12s and you could tell by the coding numbers they were not correct. I don't know just trying to get you prepared for when you get your DME back. I think after the DME and the injector/coding issue is resolved you will be fine. I think the most import part is looking at those injectors and figuring out if the numbers are coded correctly. If they are then you need at least cylinders 4 and 5 changed to index 11/12 injectors to get it running back like it should.

heres cylinders number 3&4. I sent a message to the guy we bought them from. I’m guessing they’re not open on the weekends.

Yea I've never seen index 11/12 with flow values so high other than with the china knockoffs. Hell not even index 1-10 are that high. I'm not saying they don't exist I'm just saying I've never seen them and I've done a lot of replacements. What I'm seeing is you need 5 good index 11/12 injectors (preferably index 12)

effing injector. Number 6. Not even one of the weird ones. Which probably didn’t help. we did buy 4 locally and one new one from getbmwparts.com. The other one was fine. THANK YOU for your help. Now I have to fix the brakes.
