T5 Engine Control Unit (ECU)

Hello.

I need a label file for a T5 model, year 2004, 2.5 TDI AXD, 130 HP.

Control unit No. 070 906 016.

I had my engine control unit (ECU) tuned through the diagnostic socket.

I also saved an error.

Control unit 2 for radiator fan defective.
P1949-00-Interrupted.

I have deleted the errors.
"Lately, the engine hasn't been running as well. The performance is like it was before the tuning."

The company told me that I shouldn't install any software updates, otherwise the performance boost will be lost.
I've only cleared the error codes with VAG-COM, and since then, the "normal power" has been restored.

Can anyone tell me if there might be a connection here, or if anyone has a label file?

Okay, here's the translation:

Thank you.

Regards,
Christian.

When errors are deleted, various learned values are also erased, but the engine control unit should relearn these values after a short period of driving. However, if an engine doesn't run correctly after clearing errors and learned values, it usually means that a sensor is no longer providing the correct readings, or that some parameters in the chip tuning are not set correctly.
