Just to confirm here, nobody has tried the CWKONLS renumbering and how it relates to readiness?

readiness failure with no rear O2s plugged in but coded as described in the s4wiki
Set CWDLSAHK to zero |

I am interested in this as well. I will try to look in DIMC tonight to see if the bytes set by CWKONLS are the same ones used to determine the readiness testing for the rear O2's. |

Set CWDLSAHK to zero It is set to zero, unless I have the wrong address.. 0x18663? |

Good eye! No they aren't zero. They are in my map pack, but not the wiki. |

I set those to zero and never got it to work... Maybe I needed to run the readiness tests with them set to off.

I dont know is that what you are looking for, but I set all my redines passed.
If you unplug some part like lamda you will get code, and you can put resistor on it and all is ok.
But if you get code sai incvorrect flow, you cant disable it mechanically.
So look (551M) 0x18194 there is all your rediness bytes.
Put 0 and rediness says passed and it does not matter if you have faultcodes all is still passed.
Hope your understand what I mean.
Regards:
Janne

The information below is my understanding on how readiness is set. All the information was obtained from studying the FR. Do NOT blindly disable functions with the code words below, as this may have other affects.
Below is the breakdown of the readiness byte.
The "Init bit" is checked to determine if readiness is required. If the init bit is zero then there is no fault check and the respective readiness bit is set to zero.
If the init bit != zero then the faults listed under "Errors checked" are tested. If no faults are found, then the readiness bit is set to zero.
The "Codeword" listed sets the init bit. If the codeword is set to zero, the init bit is set to zero, no fault check is performed, and the readiness bit is set to zero.
Readiness Byte
Bit 0 : Catalytic Converters
Init bit : B_katfz
Errors checked : E_kat
E_kat2
Codeword : There is no codeword to set B_katfz, but CDKAT disables creation of the error class.
Bit 1 : Catalyst Heating
Init bit : B_kath
Errors checked : none
Codeword : None, B_kath is intialized at 0. This test is not run.
Bit 2 : Evaporative Emissions
Init bit : B_cdtes
Errors checked : E_tes
Codeword : CDTES
Init bit : B_cdldp
Errors checked : E_ldp
E_tesf
E_tesg
Codeword : CDLDP
Bit 3 : Secondary Air Injection
Init bit : B_cdsls
Errors checked : E_sls
E_sls2
E_slv
E_slv2
Codeword : CDSLS
Bit 4 : Air Conditioning
Init bit : 0
Errors checked : None
Codeword : None, this test is not run.
Bit 5 : Oxygen Sensors
Init bit : B_cdlsv
Errors checked : E_lsv
E_lsv2
E_lsh
E_lsh2
E_latv
E_latv2
E_lash
E_lash2
E_latp
E_latp2
Codeword : CDLSV
Bit 6 : Oxygen Sensor Heating
Init bit : B_cdhsv
Errors checked : E_hsv
E_hsv2
E_hsh
E_hsh2
E_hsvsa
E_hsvsa2
Codeword : CDHSV
Exhaust Gas Recirculation
Init bit : B_cdagr
Errors checked : E_agrf
Codeword : CDAGR

nyet - are your rear o2's still plugged in? did you have to do any tests? or just set CWDLSAHK to 0?

Nope. Rear O2s totally disconnected. I was missing CDLSHV and CDLASH. I ran through readiness with the VCDS wizard (after warming up the car to 80C) |

The VCDS readiness worked with what is mentioned here! This means that the wikis up-to-date.
