Let's have a (hopefully) final look at Diesel emission cheating. This technical talk summarizes what I learned by reverse-engineering dozens of engine ECU software, how I found and characterized "interesting logic" which, more often than not, ended up being a court-approved "defeat device".

What started as a "curious investigation" in 2015 to obtain a ground truth to widespread media reports of "VW being caught for cheating" ended up as a full-blown journey through the then-current state of the Diesel car industry.

In this talk, Karsten and Felix will walk through the different implementation of defeat devices, their impact on emissions, and the challenges in documenting seemingly black boxes in court-proven expert reports.
