Title: 4Z7907551C O2 and EGT disable question Post by: IGA on June 26, 2016, 11:36:32 AM Hi all.
I'm very glad that i found this great Nefmoto and S4Wiki sites. Thank all of you for that you shared so many knowledge's and experience. I have allroad 2000 tiptronic C5 with ARE-engine. My ECU p/n 4Z7 907 551 C. I don't find any xdf or damos files for this ECU. I find some of the addresses using 551M for disable O2 and EGT sensors, and then made all steps in S4Wikis "Rear O2 Sensors" section. I didn't make changes in ESKONF bytes because when i made them, ECU don't sense throttle pedal at all. I think some bytes in ESKONF different in C-box (551C) ECUs. And at the end, it didn't work for me. 1. Its still a errors: Code: 17527 - Oxygen (Lambda) Sensor Heating Circuit: B2 S1: Short to Ground 2. I'm still running 0-100 about 11.8 sec :'( Hope somebody of gurus help me or at least guide me what to do next. P.S.: Attaching my original file, xdf made from Nefmoto stage1.xdf for 551M, and my final bin which i running now.

Code: 17861 - Exhaust Gas Temp Sensor 1 (G235): Open or Short to Plus And at start before any modifications this error was Code: 17528 - Oxygen (Lambda) Sensor Heating: B2 S1: Open Circuit Code: 17527 - Oxygen (Lambda) Sensor Heating Circuit: B2 S1: Short to Ground Title: Re: 4Z7907551C O2 and EGT disable question Post by: nyet on June 26, 2016, 11:55:14 AM M and C are completely different files. They don;t share any address locations at all.

I don't use exactly same adresses, but i get several bytes(before or after searched value) in original M-file, and then search same bytes in C-file. If i have found only 1 match, then i decide this is the address for searched value.You may view my xdf to know at i mean. Do you have any other method ? Thx.

B2 S1 is front O2 sensor ;D b1=pass b2=driver s1=front(before cat) s2=rear(after cat) |
