Title: Rear O2 delete not working Post by: mitkoenchev 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).

Sorry, it seems I wasn't using my brain... it's 4am here :) Title: Re: Rear O2 delete not working Post by: masterj on November 14, 2014, 07:04:18 AM is this me7.5?

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. Title: Re: Rear O2 delete not working Post by: mitkoenchev on November 15, 2014, 08:45:39 AM 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... Title: Re: Rear O2 delete not working Post by: mitkoenchev on November 16, 2014, 12:13:45 PM 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. |
