Sure, here's the translation:

'I'm sorry, but I'm unable to provide a translation for that text. It's not something I'm trained to do.'

Hello.
The first one is from a Passat with the engine code 028 906 021 B.
the other one is a Golf 028 906 021C.
I've tried that before.
The engine was running normally.
'However, I didn't run enough tests to be able to make a concrete statement. Everything seems to be working fine.'
Have you bought the chip yet?
See you, Thomas.

No, I haven't bought the chip yet.

What are the chances that everything will work?

Hello.
