[BiturboS4] Do S4s have EDRs?

Sounds right, and the same applies to virtually any parameter that is
electronically controlled or monitored (e.g. throttle position, RPM, speed,
etc.).  All of these are stored to some degree or another, not only as DTCs
("fault codes") or configuration data.  I'm not the one who can tell you
whether this stuff could be used to reveal information about an accident,
but the various control modules store all kinds of data that is accessible
to someone who knows how to get to it.
