There's zero chance that the CTO at a company as big as VW is going to be personally committing to code repos.
We know that VW did not write the code. It was the supplier Bosch that did it. VW simply activated a feature through configuration.
"33. Supervisors B, C, and F, and others, however, realized that VW could not design a diesel engine that would both meet the stricter US NOx emissions standards that would become effective in 2007 and attract sufficient customer demand in the US market. Instead of bringing to market a diesel vehicle that could legitimately meet the new , more restrictive US NOx emissions standards, VW AG employees acting at the direct of Supervisors B, C, and F and others, including Company A employees, designed, created, and implemented a software function to detect, evade, and defeat US emissions standards.
tl;dr : Bosch (company A) along with VW employees created the evasion function at the behest of supervisors.

My great hope is the VW emissions scandal where the CTO of the company had to commit lines of code that said “do billion dollar crime”.
In a git repo.
We can see your crimes now.
Wikipedia is this in microcosm - we can see the edits, we can use software to watch for us, everything is in the open and the feudalism and rent seeking exist best in the hidden darkness
What we do with that is up to us.
