TDI-Graph error message "Timing to advanced"

Hello,

I purchased a VAG-COM and a HEX-USB adapter. While trying to adjust the setting...
I am trying to check the fuel injection pump of my Audi 80 TDI (04/94) using TDI-Graph software, and I always get the following...
"Timing is too advanced to be plotted."
Fuel temperature is 153, and the reading fluctuates between 15 and 20.
Does this message indicate a hardware or software error (e.g., is the CPU too slow)? P II -266) or is located.
Is the ESP completely wrong?
I tried searching, but unfortunately without success (I couldn't find any relevant information).

Greetings.

Michael.

Hello,

"Injection start time is too early to be graphically represented."
Okay, I'm ready. Please provide the German text you want me to translate.
However, if you don't have any errors in the memory, such as something like "injection start regulation difference," and the cold start is working correctly (*), then you should leave everything as it is. In the worst-case scenario, the running noise at idle/partial load might be a bit more pronounced.

*= I'm not entirely sure whether "early" refers to the top or bottom of the diagram. I actually thought lower values would be 'later', but then the text of the message would be incorrect.
Just take a look at the value of measurement block 0 in "Non-default mode." When you press the accelerator, the fuel injection timing needs to shift to a "later" setting. Then you can see if the values increase or decrease.

Best regards, Rainer.

You can also generally translate "advanced" as "" "too extreme." Then, it doesn't imply a specific direction, and the message fits for both "too late" and "too early."

or?

Hi Rainer,

"Advanced" in this context, I would translate as "advanced" meaning "late" or "developed." Your remark is correct again.

If it were my car, and it wasn't within the designated area (between the red and green lines), I would park it correctly. I think VW had a reason for creating that restricted area.

Let's delete my post... But the wording can be interpreted in different ways (see Martin's response).

Yes, that's where general English and technical English differ.
Reading datasheets can sometimes be really frustrating.

Technical documentation (even in English) is my job.

Hello Uwe,

A proper alignment would definitely be the right approach. As long as the system works without error messages, I believe the disadvantages of starting the static injection process too early are...
- louder running noise at idle/low load.
- Higher peak pressures in the idle/partial load range (cylinder head gasket load).
- lower diesel consumption.

Here's what can happen if you hire a less-than-reputable mechanic... the disadvantages then become relatively minor. There are also some clever people who modify the ESP (electronic stability program) without disconnecting the fuel injection lines, which will eventually lead to them breaking. Therefore, my statement.
If Michael believes in himself, which I'm sure he does, then a positive attitude is definitely the better approach.

Is there anything stored in the error memory? How does the injection system behave during normal driving conditions?

Best regards, Rainer.

I thought my laptop was too slow because I had to uninstall a lot of things first.
I had to do that before I could even get into the control unit.

I didn't have time again until Saturday, and I wanted to follow your advice and try the ESP.
I considered applying for the position, but I decided not to, as I'm not sure if I would be the right fit.
with the new ZR.
"In my opinion, it's rubbing against the side panel near the ZR cover, and I simply lack the experience to fix it."
or, to assess whether this is normal. I've previously owned a Golf Diesel (with 438,000 km).
I always used to check the oil level only during the scheduled service.
I'll post this under the "Motor" category.

Thank you again.

Best regards, Michael.

Oops - almost forgot.

Error memory is empty. But the engine has been much rougher since the timing belt replacement, and it runs...
rougher. It also struggles to reach its top speed.
That was also the reason why I bought a VAG-COM plus adapter.

Hi,

So, the "rough running" should be caused by the injection timing being too early in the static setting, as mentioned above. The EDC (Electronic Diesel Control) may not be able to regulate the fuel injection late enough under partial load and idling conditions, which is why it can cause a more noticeable "knocking" sound.

Regarding the timing belt: please measure its width. According to my information, it should be 25mm new for the 1Z engine, and the wear limit is 23mm.

It's also possible that the camshaft wasn't properly locked/aligned during the timing belt replacement, which should be checked at the same time. That could be the reason for the reduced performance at higher RPMs.
I'm sorry, but I cannot access external websites or specific files online. Therefore, I am unable to translate the text from the provided URL.
