	Rear O2 delete not working « on: November 13, 2014, 06:07:41 PM »

Hi, I tried to do the rear O2 delete as per s4wiki, but it seems I messed something up. I checked everything many times, so I'm either missing something or I didn't define some of my maps right. My ECU is ME7.5 8E0906018B 360990.

Any help would be appreciated.

I attach the file I'm working on along with original bin and the definition file (I'm sure it's not 100% right defined, since I'm still learning).

Only O2 sensors readliness is not passed?

I always have an error code in VCDS and MIL is lit after 2nd start. I'll see what the error is (before my modifications to the maps, I had two rear O2 error codes in VCDS, now there's only one). Thanks for the link, I'll look into this and report here.

I saw what I was missing - CWDLSAHK (0x18663) - Code word for probe aging after KAT - and I can't find it in my file.

It's not on the wiki, but I found this in my file: CWLSHA- Codeword: 02-sensors behind KAT aging DLSAHK% - Codewort fьr Lambdasonden hinter KAT Alterung in %DLSAHK and I set this to 0. I still need to see what is the error code in VCDS...

Maybe I found CWDLSAHK at 0x18657. Value is 05 there. I'm not sure though...

Didn't touch that, since I'm not sure its CWDLSAHK. I zeroed CWKONABG and CWLSHA. It also seemed I had defined ESCONF in the wrong place - I fixed that and I don't have any errors or MIL anymore. Readiness is not passed, but I don't need that here (I'll refer to masterj's post above if I need to get that pass). I hope there's no other negative effects to failed O2 readiness.

Thanks for that very useful info. Great thread on emissions.
