Differentiate PRE-DIESELGATE vs POST-DIESELGATE sw
I have a 2018 Audi A6 C7.5 3.0 TDi (CRTD) with 272 hp and wanted to downgrade to pre dieselgate software

Version 0002 (released march 2015) is 100% pre-dieselgate. 0007 (2017-2018) is 100% post-dieselgate.

Can anyone take a look at the ecu maps and tell if 0003 (June 2016) is Pre Dieselgate or Post Dieselgate?

Also 0003 and 0007 have the same corresponding TCU versions.

Did a quick look, but I would say 0003 is Pre-Dieselgate. Very small changes, fueling maps not touched and very small changes in SmkLim

However, as far as I'm aware, the EA897evo was found to be illegal by German court in approximately 2020 or 2021
