Fuel Injector Start: Automatic Adjustment

Morning, Foriker.

"I had the timing belt replaced about 4,000 km ago on my 81 kW AFN engine. Afterwards, I checked the fuel injection timing using a TDI-checker. It was slightly earlier than the ideal setting."
Now, after approximately 4000 km, I checked again and found that the injection start timing is exactly on the "target" line.
Is this normal? (Belt expansion)
Has anyone ever had this experience before?

Okay, here's the translation:

Thank you.
Greetings.

Hello, I would say that your timing belt has stretched slightly over time. This can sometimes happen, especially since it's only measured in millimeters.

Best regards,
