You can downgrade only with VAS, or VCP...

Watch for ODIS-E (in this forum available) and VAS5054A adapter and you'll able to flash it back with the original flash files from VAG

If you have made an update and after that you have problems like injection noise, high consumption or problems in the EGR you can go to the mark to complain, because if you have made revisions or if you have not been updated for a short time, the brand paid what has to be changed.
