Tell me what bits you wish me to set to 0 on my bench ECU and I'll gladly do it and take a screenshot of the OBD-II module.

Also for the guys that have a VAGCOM 409, just download VCDS Lite and use that for the OBD-II module. Of course, nothing beats an official VCDS interface but this should work Smiley

These:
VCDS displays "Passed" for all readiness checks. See below for secondary O2 changes in my file.

All set to zero:
CLAHSH
CLAHSH2
CLAHSHE
CLAHSHE2
CLALSH
CLALSH2
CDHSH
CDHSHE
CDKAT
CDLASH
CDLSH
CDLSHV
CWDLSAHK

After flashing these changes, I ran the readiness checks for the O2 sensors per the Ross tech wiki.
http://wiki.ross-tech.com/wiki/index.php/Readiness_-_APB_Engine_Code

Cat heating and AC should be the only ones unsupported.

VCDS-Lite only tests compatability just like 409.1. Unless I need to update it.

I'll do it tomorrow when I get back to the shop. I don't do any tuning on the weekends  Tongue

But just so you know, I have 0'd out those bits and it gives me unsupported but I'll give it a shot again and show you.

Can you post a shot of the Engine control module readiness screen as well?

Update:

With those bits set to 0, Connecticut emissions computer reads it as 'Unsupported'. However, this did not prevent it from PASSING. YMMV as always, but it works for Connecticut.

I figured you didn't post your results because they weren't what you were expecting.

I'm not sure why they would show as unsupported because none of those changes should affect evsup.

What bit was unsupported? Oxygen sensors?

Everything that you set to 0 gets set to not supported (specially the 'euro-bytes').

E.g
CDSLS
CDKAT
CDLSV
CDLASH
CDHSH
etc

Homie if you set CDSLS to 0, SAI will show up as unsupported.

Unless my memory is failing me hard right now, which I really really doubt since I do this on a daily basis.

Agreed. I didn't touch CDSLS.

hey everyone!
Maybe you could tell me where my DTC table begins?

Because I don't have damos file for my specific sw, but bits in 0x18190-0x181C0 range seems to be OK. Now I don't know how to disable actual DTCs:

17526 - Oxygen (Lambda) Sensor Heating; B1 S2: Open Circuit

        P1118 - 35-00 - -

17522 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High

        P1114 - 35-00 - -

Because all the other addresses given are way off... Smiley I even don't how to recognize DTC table start so I could atleast try Tony's method of DTC error address calculation posted here: http://nefariousmotorsports.com/forum/index.php/topic,567.0title,.html Any help would be appreciated Wink

Add CDLATV to the list. This solved the problem of O2 sensor readiness not completing on it's own.
