I replaced my #3 injector yesterday and while doing the adaptation I noticed that the other 3 injectors code on the injectors do not match with the id numbers that was listed in the vcds software. I know the engine was changed at some point prior to me buying the car. I assume, whomever that changed the engine, did not take the time to code the ecm to the injectors numbers that are in the new engine. I've been driving the car for over a year with no injector codes with exception to the #3 injector that I changed out, and also have noticed I'm not getting as good fuel economy that I maybe should. Only truly noticeable issue is quite a bit of fuel smoke out of exhaust when initially starting car after several hours of the car sitting. Also tends to be more smoke when its temps are cooler.

Should I code the ecm to the correct injector numbers that are remaining in the engine, or just let it ride till I can afford to swap out the remaining injectors with new and code them correct at that time??

Thanks!

I would have a look at injector deviations. If they're acceptable, leave it alone until you replace the other three. If they're not, then I'd try to code them in.

Couldn't get the photo to load here, but here are my results with the information you inquired about:
Engine speed (G28): 828 /min
Coolant (G62): 90.0C
Injector quantity deviation Cyl 1: -0.71 mg/str
Injector quantity deviation Cyl 2: -0.28 mg/str
Injector quantity deviation Cyl 3: 0.71 mg/str
Injector quantity deviation Cyl 4: 0.24 mg/str
fuel consumption: 0.63 l/h

Leave well alone !!

I say that because you do not have enough info from the past to make any decision !!


Quite often Injectors are "rebuilt" and the rebuilder has no way to test and produce a calibration number for that rebuilt injector - So the code stamped on it is wrong.

Injector quantity deviation Cyl 1: -0.71 mg/str
Injector quantity deviation Cyl 2: -0.28 mg/str
Injector quantity deviation Cyl 3: 0.71 mg/str
Injector quantity deviation Cyl 4: 0.24 mg/str
All that is perfect !! Leave the thing alone !!

If you really cannot help your self then at least note the codes in there now so you have a rewind strategy !!

I agree, that's not bad at all, and I'd leave it alone.
