	trying to disable rear cat DTC entirely in my european Audi A4 B6 3.0 ASN engine « on: January 26, 2016, 05:07:07 PM »

guys,

can you help me to disable rear cat DTC entirely in my 2002 Audi A4 B6 3.0 ASN engine? I'm unable to find a XDF suitable for my ECU. After reading the Tunning S4-Wiki, i will need address of the following memory positions:

CDKAT
CWDLSAHK
CDHSH
CDHSHE
CDLATV
CDLASH
CDLSH
CDLSHV
CWKONLS

See my ECU details:

Producer: Bosch
Build: ME7.1.1
ECU-Nr.Prod: 8E0909559M
ECU-Nr.ECU: 0261208238
Software: 367278

and see my ECU file attached to this message.

thank you in advance for your help.

Here is the AVK 3.0 559E file that removes SAIR and CAT. I've flashed it over 559D and others I believe. Its based off the 0001 sw version. DD posted it awhile ago, but I couldn't find it last time I looked. Might be ok for your car....might not....Make sure you have the tools to bootmode flash if you plan on trying it. I'd compare it to your bin and adjust accordingly.

Workshop2,

thank you for your answer.

still trying to get rid of the " P1140 Bank2 Sensor2 - O2S Internal Resistance too high" DTC in my 3.0 V6 Otto ASN engine.

Because one of my post-cat is out of service and my B2S2 o2 sensor is not OEM, i've been working during the last weeks on my 3.0 ASN Eeprom (with Tunerpro, WinOlS, MPPS ...) in order to get rid of all DTC. So i made good progress with everything except with the fucking "P1140" DTC. No way to shut it down. Yes, i zeroed the "1819E" address.

I've been reading a lot the Audi S4 tunning wiki and all the forum messages, specially this one which is the most clarifying one:

http://nefariousmotorsports.com/forum/index.php?topic=60.msg96#msg96

so, can any one provide any additional support to me? I know my 3.0 ASN engine is not very common between us. Cry

and please, excuse my written english, i'm a spanish speaker.

thank you in advance everyone.

Looks like your fault is at 0x1C4CC and the start of that that table is 0x1C2BC. I don't know how that error table is setup in ME7.1.1, but I did spend some time trying to dissable a DTC on one this week, and I'm fairly sure 0x1C000 is the start of the Error Code Class Table. I'm not sure if the equations are the same as they are in that thread for 7.1.1, but it should give you some place to start.

And you may need this :

And this may help. I have NO IDEA if these are correct for your file, but the 0x1C000 lines up.

still trying to get rid of the " P1140 Bank2 Sensor2 - O2S Internal Resistance too high" DTC in my 3.0 V6 Otto ASN engine.

ESKONF for 8E0909559M is between 0x1115d and 0x111c4
Changing byte #5 from 02 to C2 should remove the DTC for B2S2 O2 sensor.

Code:

00 00 00 10 (LSHHK2 installed) -> 02
11 00 00 10 (LSHHK2 removed) -> C2
11 11 00 11 (LSHHK1 installed) -> F3
11 11 11 11 (LSHHK1 removed) -> FF

These are what I would use for both rear O2 deletes:

Code:

0x1115d
0C C0 BF F0 00 C2 FF FF AA FA 55 55 33
0C C0 BC F0 00 C2 FF FF AA FA 55 55 33
0C C0 BF F0 00 C2 FF FF AA FA 55 55 33
0C C0 BC F0 00 C2 FF FF AA FA 55 55 33
0C C0 BF F0 00 C2 FF FF AA FA 55 55 30
0C C0 BC F0 00 C2 FF FF AA FA 55 55 30
0C C0 BF F0 00 C2 FF FF AA FA 55 55 33
0C C0 BC F0 00 C2 FF FF AA FA 55 55 33
0x111c4

It seems like one of the difference between ASN and AVK engine is the V144 the leak detection pump.

Metronet,

no lucky. Still having the "P1140 Bank 2 Sensor 2 - Internal Resistance too high" DTC. I did modify my .bin as you wrote in your post.
