ECU Same? Check Compatibility Now!

Hello.
Are the control units with the part number 1Z always the same?
"Will an engine control unit (ECU) from a Volkswagen Golf 3 also fit into an Audi 80 B4 if they have the same engine code (MKB)?"
Best regards.

[Edit Admin ??????? shrunk]

No!

Even Golf 3 models are not necessarily compatible.

Best regards,
Rudi

Hello.

Okay, that's annoying.
Thank you.

Sure, here is the translation of the text from German to English:

"MFG" is an abbreviation for "mit freundlichen Grüßen," which means "best regards" or "sincerely." It is commonly used in German-language emails and letters.
