As far as I know it will never clear the codes. Just recalibrate.

Unplugging will not clear codes... but it will cause a low voltage code to be set.

You must use a vag scan tool to clear codes.

Nope, you need a scanner.

Is there anything complicated about swapping ECU's if the codes are the same?

Could anyone tell me how to clear the codes that arise when switching back to the stock ECU?
