[V8] Pro Diag Died? Was O2 Sensor Readings

[Kneale Brownson]

Pro Diag is no more?  Here I was planning to keep it for newer cars (if I manage to outlive my "teenaged" Audis), where it reportedly would have been really useful.

VAGCOM or equivalent. Unfortunately it appears that ProDiag has died ... so
unless you already have one it is no longer an option. With ProDiag I can
read out and clear the ECU codes, and I can take a test drive and log the 10
parameters the ECU provides. I suspect VAGCOM has the same capability. You
can tell right away if the ECU has decided that it cannot control the
mixture effectively (generates a code) or if it is responding to an
erroneous input (like an incorrect coolant temp).
