Injector Calibration: How to Calibrate Injectors

Hi there,

I had new injectors installed in my BPP vehicle after quite a few kilometers. (Okay, not entirely new, but refurbished with a testing report.)
The exchange involves entering the new IMA ISA values via the extended configuration settings.
My VCDS or control module doesn't accept it. When I try to test the new value, it always shows the original value as being tested.
If I enter a code that is too short, I receive an appropriate error message.
What am I doing wrong?

Hello,

Sure, here is the translation of the text from German to English:

"Screenshot?"

This translates to:

"Screenshot?"

It is a question asking if someone wants a Screenshot.

Sure, here is the translation of the text from German to English:

"LG" can be translated as "Best regards" or "Sincerely". It is a common abbreviation for "Liebe Grüße", which means "Warm greetings" in English.

It's different for me.
Extended adaptation, oA, instead of 10.

It's different for me.
Long adaptation, oA instead of 10.

And then, after I pressed the "Test" button.

Okay, the opposite.

Hi there,
Could it be that with this message (MSG), the new Instantaneous Maximum Acceleration (IMA) value is only displayed and recorded after an ignition on/off cycle, with a few seconds of waiting time?
It's not like that for me, see here https://community.dieselschrauber.org/en/viewtopic.php?t=30733&highlight=ima.
But who knows?
Perhaps a login is also required for the MSG?

So, it seems the situation is quite different than we thought.
Two of the six nozzles are assumed to have certain codes, while the others do not.
I have no idea what the detailer did wrong.
Anyway, they're coming back.

Hi there.
You are using the IMA codes that come with the documents, not the embossed ones.
I would consider all of these injectors to be unreliable (and not even one of them during a warranty replacement).
Were the old injectors that bad? And if so, are there any replacement injectors available from Audi or Bosch (or Delphi)? They would probably cost more, but they might be more reliable.
I'm surprised that when incorrect IMA codes are used, a "AAAAA..." sequence isn't output as a test result.

Yes, they are all being returned.
They call them "refurbished," but I can't see that anything was actually done to them besides cleaning.
Two protocols even show a result of "Failed."
