Title: MED 17.1.1 - Flashing back to stock - CVN Post by: golfather on July 17, 2022, 06:25:49 AM Hi all
I have a customer who has a Audi A6 MED17.1.1 which has been mapped Can it be flashed back to stock and will the original CVN will be restored? Is the ori CVN the same for all flash files of the same version from factory or is it calculated individually for each ECU id Any way of determining what version of flash it had before it was mapped without a backup? It still has a warranty so want to make sure it is fully flashes correctly back to factory settings before the dealer connects it back online Thanks Title: Re: MED 17.1.1 - Flashing back to stock - CVN Post by: prj on July 17, 2022, 07:10:48 AM VAG does not even check CVN. Flashing to stock will not help you.
Loading a backup would not always help you either, if there was something major wrong with it, non-matching mileage will set a flag during manual check. |
