We are subject to the same readiness requirements as far as I know.  I've been turned away and told to drive around and come back another day.

All states do not have the same rules  Tongue
NJ has the rule where you can only have ONE not ready/failed/unsupported monitor only. NJ knows what car has what monitors via VIN or via MY and make & model.
DE must pass ALL of the monitors.
PA is the same AFAIK.
NY has prob same regulations as NJ.

Unsupported used to fly by under the radar on NJ but not anymore.

If its a tune issue, have you tuner look at it.  what code do you get?

I'm a little concerned about readiness too.... it really depends on who is running the test.  I've hand a car pass stone cold and definitely not ready, and it once took 3 days to get a 98 911 to set readiness to be allowed to even test.

If a savvy emissions Guy sees multiple unsupported readiness monitors, its an instant flag the car has been illegally modified. This could require you to spend a buttload of cash to get it "fixed" before they flag it or at least to restore the monitors to get it to pass.

In CT, if a vehicle has been flagged, it only gets one freebie after spending a certain amount of money to try and fix the issue. If it happens again, the car wont be allowed back on the road...

I would think that maybe seeing SAI unsupported is not as bad as post cat o2 unsupported,  but I really think that will come down to the tester's experience, and maybe how much you butter him up.  Smiley

Rear O2's are not tested seperately. They are tested in Catalytic Converters and Oxygen Sensors.

Can anyone confirm that VCDS will display "Passed" while emissions testing will display unsupported?

For your bin.file I believe you have address mixed up:

DTC Error Code Class Table (8 bit table):0106AD
DTC Manufacturer P-codes (16 bits values):012CC4
DTC CARB P-codes (16 bits values):01324C

12EDC-12CC4=218
218/8=43
106AD+43=106F0

Address 0106F0 is viewed in 8bit, stock value is 03. I'm still just learning this stuff so I hope that helps. Maybe someone will correct me, so take what I say with a grain of salt.  Wink

Tried to do as tutorial says but failed and searching step... In my 1.8T when I search for 1114 i get 5 locations:
10698
18b86
18c16
1911c
194cc

Which one I should use for calculations? If I use 10698-12CC4 I get som FFFFFFFFFF stuff, which means that number is negative...
