I know myself and many other shops have seen their share of vehicles that fail NOX and NO "DTC".
That is the MAJOR flaw with OIS DAD.
Paul Hedglin, a BAR engineer, states "a hand full" of 2000 and newer
vehicles would still be subject to BAR 97 when OIS DAD goes
statewide. They, the BAR guys, just don't get it.

This is exactly the type of evidence, tail pipe failures, we need to submit to the Assembly
to argue against eliminating tail pipe testing on most 2000 and newer vehicles.
The BAR has all the evidence but they won't challenge it themselves since
the Assembly "clowns" wrote AB 2289.
The Automotive Service Council of California people were opposed to AB 2289
knowing that many vehicles would pass OIS DAD and possibly
have high tail pipe or gross polluting emission levels.
