P0263C0,P0269C0,P0272C0,P0266C0 Injectors
Hello MBworlds,
Unfortunately, I couldn't find an answer to my problem in other forums, so I wanted to ask here.
i have change Valve cover gasket. However, I'm not sure if it was like that before. I disassembled and assembled everything properly. (Clean the hole of Injectors, 15NM + 2 x 90°.... have read --> by WIS Software)
Car: W212 2010 2.2CDI I found this by accident --> Error by Xentry:
P0263C0 The teaching of the operating parameters for cylinder 1 has a malfunction
P0269C0 The teaching of the operating parameters for cylinder 2 has a malfunction
P0272C0 The teaching of the operating parameters for cylinder 3 has a malfunction
P0266C0 The teaching of the operating parameters for cylinder 4 has a malfunction Injection quantity
adjustment are correctly. Car starts normally How can I solve the problem?
Thank You

sudden amnesia...
this is your engine calling for a Xentry massage.
You understand the codes meaning... I wonder what caused the diesel ECU to forget matched injectors.
I take it, you already have access to a Xentry. Look at the code setting criteria to understand WHY the ECU logic calls up this issue on all 4x cylinders.
+++++
CURRENT or STORED fault ?

I could take a screenshot tomorrow. I think that comes from the previous owner. I have only change valve cover gasket because it was leaking.
2. Question:
Could I reset the ECU without losing the Immo setting?
Then the control unit should know the setting from the injector again (Theoretically)
Learning the injectors is easy.
By Current or Stored Faultcodes -> I cannot delete when the vehicle starts. I can only delete it when the engine is off. ( also permanent Faults )

Misleading status:
Transient faults are classified as "stored" even though condition may happen regularly or presently at this time.
I don't think you can easily brick the immobilizer system by mistake if you are careful. There's a fix for that too: @BenN....

I am not entirely sure what you want accomplished - Don't reset the ECU while the engine is running... simply clear existing codes to help diagnose status of faults: passed vs. present condition ?

Okay friend,
I will try again. I will get back to you.

Did you check injectors codes with what's programmed into ECU ?
I don't see you posted the mileage, but at high one, your injectors might be due for rebuilding.
Injection corrections looks high to me.
You might repost it in diesel section for more exposure from diesel owners.

Yes, i have check injectors code with whats programmed into ECU. All 4 Cylinders are corectly.

different
I think they are tryingto keep track the vehicle speed vs. miles.
diesel inject pulse mgt
It's interesting to see the pulse width vary with pressure. It shows the ECU trying to correct cylinder differences using historical data.

We can observe all 4 injectors supply equal amount under same conditions.... chances are these injectors are ready to be controlled perfectly by the matched ECU.
A defective injector would show a restricted output. I don't see that in the lineup, all equal flows.
In previous post you showed how the ECU involved many strategies to manage the flow to each individual cylinder, based on variables:
You should not ignore the ECU software is managing the injector output. This close loop control meets target range ULTRA PRECISELY by measuring combustion with lambda sensors.
+++++
Are you seen positive FUEL TRIM numbers because engine is burning lean ? That's better than a lean trim on a rich engine.
Performance has everything to do with how Bosch ECU sets these trims.
We see how these engines intake track is built to injest a lot of their own oil - That directly plugs the exhaust O2 + cats .
FYI: Dirty lambda hardly trigger DTC, only poor performance.

Thank you for your message. I installed new injectors today. (Also registered in the ECU via Xentry)
#Conclusion:
Error message stays the same.
I've noticed that my injectors run better with the "Common Rail Tester" than the refurbished ones. So I put the old ones back in.
I have read in other forums that you have to drive about 200km so that this error does not appear again. I test it the days.

Guys, I managed to get rid of this error. P0263C0,P0269C0,P0272C0,P0266C0 Injectors.
I drove 20 kilometers. After that I cleared all errors. Before that the errors came constantly. Now there are nomore errors. I think he taught himself.
Thank You

- putting your old injectors back-in
- clear codes and
- drive around some distance
helped clear your ECU: that's fantastic . Thank you.
😄
