jetzt habe ich somit ein Originales System und ein geringes rußen. Die Frage ist jetzt, wie stark darf ein AFN mit 240000km rußen?

If it's just the initial nozzles, then it's already "quite good."

Habe dann mal ein log mit 3 8 10 gemacht, auffallend ist, dass der LMM bis zu 1115 anzeigt, kann das ein Problem darstellen?

Oh man, why are you clinging so desperately to the completely useless AGR-MWB 3 when you're going full speed ahead?
The air mass is also listed in the MWB 10.

If you had omitted MWB3, the log series would be 50% longer, resulting in finer resolution without any loss of information that is important here.

Your air mass - load (LD) ratio seems a bit high, as if there's still an air leak somewhere. Is the EGR valve closing properly?

Please store your logs in a way that the numbers are actually recognized as numbers, otherwise you won't be able to create charts or perform internal checks like calculating the relationship between air mass and lift-drag (LD).
Normally, converting text fields to numbers would already warrant a beer .

Sorry, I will improve .

The nozzles are new, but the nozzle holder is the old one. The question now is how important it is if the opening pressure deviates slightly?
Since this is original power output, there should be plenty of reserve capacity, right?
The atomization is working correctly; I had checked that beforehand.

Unfortunately, there isn't a Bosch service center in this area that is capable of handling injectors. There's only one, and he wants over €100 just to verschandeln them without making any adjustments.

The AGR is 100% leak-proof (I'll post a photo of it later this evening).



If you happen to bump into me, I'd be happy to offer you more than just a beer ).

"Nevertheless, with boost pressure X, approximately 20% more air mass flows through the mass airflow sensor (MAF) compared to naturally aspirated engines, and I find that unusual."

Did you reduce the LD value, tamper with the LMM, or perhaps lose the catalytic converter?

Or did your tuner possibly increase the MAF sensor curve in the software because he couldn't find the misfire?

Hello vc,

No, your methods are not informative; rather, as already mentioned by cksit and matthiasTDi96, they are nonsense.
If you practice engine building like that, I would never give you any orders.

The boost pressure at idle is a joke, even with the VTG completely closed, namely an optimistic 150-200 mbar. Here, we're talking about sealing at approximately 1500 mbar!
Also, with the engine running, you can hear a hissing sound, especially if the hole is small.
The other two have already said everything else.

Best regards, Rainer.

No, the LMM is genuine, but you might be right about the catalytic converter...

It should actually help more than increasing the soot content, right? (I never thought the catalytic converter would play such a significant role in that.)

And that has nothing to do with the tuner since an original control unit is installed...

Here are two pictures of the AGR . I highly doubt anything will get through }.
