Have a look at this thread; http://nefariousmotorsports.com/forum/index.php?action=printpage;topic=8898.0
I realize its ME7.1.1 but it might be similar

It looks like it is not in ESKONF, I try to FF all last 4 bytes. DTC still there
I didn't learned that ASM skill yet
 

DONT NEED ASM to do it

How to find DTC and zero it?


EXAMPLE: P1523
1070F is the start of your error class table.
Hint: There's almost always a 01 7F in front of it. A lot of times 01 7F 0F 00, where 00 is the start of
the table. Some files this is 01 7F 50 00. (again, 00 is the start of the table).P1523: The first occurrence is at 1361D. Scroll up until you see four blocks of 0000. The address of
the first block is the start of the VAG specific DTC table. In this file this is 1327A.Now: USE WINDOWS CALC IN PROGRAMMER MODE
1361C - 1327A = 3A2
3A2 / 8 = 74
Now find the start of the error class table 1070F
1070F + 74 = 10783
00 the byte at 10783

i have a PDF with pics if needed

Nyet can you add this to the Wiki for Rear O2 full removal. I chased my tail for MONTHS... Ask Gremlin... I read so much then started turning off the codes 1 by 1 because i knew either CDLSH or CDLASH was causing the front O2s to not pass. for ME7.1.1 on ST10 i needed to change these settings like above and "FINALLY" passes with no rear O2 plugged in at all and all systems passing.

So I have something to add here. DLSU will NEVER set z_lsv = 1 IF b_sbbhk = 0! OR at least on 06...HN file with fully defined ols. It is almost complete single bank copy of FR file we all have here. Problem lies within DLSH. So I would like you to consider the following mods to the "current" community emissions delete process:
CDLSH.0 = 1
USMIN = -1
TANHKMMN = -273
THSHA = 0
TRSE = 0

When we leave DLSH enabled we can finally set b_sbbhk and thus enable diagnostics of DLSU. I can confirm that now finally I have z_lsv set and all readiness passed.

Of course it would be way nicer to fix everything with codewords, but I see no other way to set b_sbbhk other than keep DLSH enabled.

Just an update/clarification: I can confirm on ME7.5 018CA and many other ecu's/ME7's it will not pass readiness on Oxygen Sensors if DLSH is completely disabled because Z_lsv wont be set as 1.

Even if the checked error flags are 0 - E_lsv , E_lsh, E_latv etc. the Z flags must be set aswell or it will not pass readiness.

Solution is in masterJ's post or you can modify the code directly in asm, either force b_sbbhk to the required value, or change the jump command.
