P0611 Injection Issue 2020 Vantage (MB M177)

[paralis]

Hi all,

I m currently dealing with a P0611 fault code **The fuel injector has a malfunction (output stage fault of combustion engine)** on
my 2020 Aston Martin Vantage (M177) and I m trying to better understand the injector calibration / coding process.

Does anyone here know the following:

1. Do the injectors on the M177 in the Vantage need to be individually coded (like Mercedes CDI engines), or are they self-adapting?
2. When the AM dealer programs the ECU using the original configuration file for the VIN, are the injector calibration values already included in that dataset?
3. Or is injector coding a manual process where the injector correction values must be read directly from each injector (QR / alphanumeric code), noted down, and then manually entered during programming?
4. If reprogramming is required: do the injectors need to be physically removed to read the calibration numbers, or can they be retrieved via diagnostics?

The background:
A new ECU was programmed because the old one was damaged and it was impossible to backup the data. I m wondering whether the injector values may not have been properly written during flashing. I d like to minimize unnecessary labor if possible before removing injectors.

Any experience with M177 injector coding on the AM calibration side would be highly appreciated.

Thanks in advance.

Frank

1 They need coding
2 Injector coding is a separate process
3 They would usually be copied from the original ECU. Otherwise use the QR codes.
4 You don't need to remove the injectors to read the QR codes.

Hi Kaban,

thanks for your reply, from what I can see, everything in that engine bay is packaged so tightly that even light barely gets through let alone my eyes spotting a QR code somewhere down there.

Seriously though, it looks like there s virtually no visible access to the injector bodies while installed.

Are the QR/alphanumeric codes actually readable in situ on the M177, or is there some hidden Aston-approved yoga position required to see them?

Or can the calibration data be retrieved electronically via diagnostics instead?

Trying to avoid turning this into a full disassembly adventure if possible.

Thanks!

The code is printed on the black plastic part of the injector that fits into the fuel rail.

You can read back the codes from the original ECU, but you've already said that's not possible.
