Hello.
There used to be a table somewhere with target values for various VAG TDIs, including information on fuel quantity, injection timing, etc. Unfortunately, I can't find it anywhere now, and I need to check if the previous owner has already adjusted the starting fuel quantity, injection start timing, etc., on my Audi.
If someone has the right line, bring it here icon_smile.gif.
Thank you for the tips.
Greetings.

Hi, the table doesn't make sense because the engine control unit (ECU) already provides all those values. Why would we need to write them down again?

Hi Rainer.
The table is floating around here; it contains data for most VP-TDIs. It includes things like idle speed, rev limiter speed, fuel injection start timing at idle, etc.

I need to know the following values (for a vehicle with a 2.5 TDI AEL engine) in order to determine which channels the previous owner has already adapted, and whether the pump cover has been moved (it was removed at some point).

- What is the standard injection start value for a warm engine?
- What are the target values for the various parameters when the engine is idling?

That would be a great help, and it was also mentioned in the table.

Is there anything else? Do you have any tips on how I can find out if the initial amount has ever been changed?

Greetings.
