ECU registered by previous owner
Posted: Tue Nov 25, 2025 4:48 am
I’ve got a new-to-me S4R that I am attempting to get registered through the JPdiag website.
When entering all of the relevant fields, I get a return message stating that the ECU has already been registered.
Is there anyway to reset the registration?
