On a 04 passat 1.8t I am having issues setting the readiness after clearing the codes for secondary air combi valve that got fixed. I cant seem to get the pre cat O2 test to run but got it to run a year ago. need it done to pass emissions and will try it again after more driving. I am getting the same results on both my x431 and k-cable tools

basic settings-04
group
060 - Evap purge test runs to EVAP OK
107 - A/F control test runs to Syst.OK
041 - O2 sensor heater test ran to completion
036 - Post-cat O2 sensors readiness test runs to B1-S2 OK
034 - Pre-cat O2 sensors response time test never switches to test on
046 - Catalytic converter test runs forever
077 - Secondary air injection test runs forever

I THINK there's a way to make a VW run all the monitors in the bay...
I just heard it the other day too, gotta try to remember...

that is basicly what I was doing by running each those groups under basic settings for the engine, I was bidirectionally running each the test and one did not want to run. that is unless you know a different way of run the test

Probably not, that's gotta be what I was thinking.
I should have read your first more clearly.

its fine in that vw is a odd ball, basic settings-04 is there bidirectionally test controls and you need there codebook for definitions
