Bahh....one successful read/write session and about 30+ failures. This "S" box is a real PITA. I've tried two different ECM's, three different cables, two different power supplies and I still can't get consistent read/writes.
Update: Well, for anyone else who's interested, I think I finally found the "key" to consistent reads/writes. No mystery as I read it in a few other threads but I started leaving 5-10 minutes between attempts. (powering down in-between of course) Since I started doing that I've had 4 successful reads and 3 successful writes. I don't know if all ECU's require this much pampering but mine does.

So, in bench there is no issues to read/ write the EEPROM either over OBD or bootmode, right? If you are having trouble reading Sbox with the ecu in the car probably this is due the instrument cluster disturbs the communication.

Correct, no issues on the bench. Another thing I did was dis-assemble and remove the extra wires coming out of my junkyard ECU connecter. (it was fully populated with wires) There's only a couple now.
I haven't gone back to try the ECU in the car again. My first attempt at connecting was with 3.0. After I realized I was using 3.0 I then switched to 3.1 but at that time I hadn't been using a 5-10 minute wait period.
Wondering if I should just unplug my instrument cluster? Still being a little cautious about actually putting my good ECU in my bench setup. Probably just paranoid.
I should add that I was waiting 30-60 seconds (powered down) for all my experimenting prior to this but that doesn't seem like it was enough. I noticed the PCB does have two fairly large capacitors (compared to the majority of the microscopic one's used on most PCB's) so those might take a while to dis-charge.
UPDATE:
Unplugged my instrument cluster and was able to get a clean read (no failures at least) on my first try; ECU installed in car. Will flash that file to my spare ECU tonight. Do the ol' switchero tomorrow.
UPDATE:
Flashed my spare ECU. Connected with my genuine vag-com cable and the VIN (etc) info that comes up matches the ECU in my car. me7_95040 -SKC reports same skc code as what's in my car as well. Lookin' good!

Well I believe I have success. Swapped in my flashed ecm, connected with vcds, cleared all codes and then fired it up. Car stayed running, no CEL,. Restarted three more times, no problems. Sweet! Finally. I'm now equipped to train others LMAO

Error 07h is time out, error 01h is a general error (think I have to include a better description about this error) and error 0Bh is check sum (communication chksum) which is strange because its only used in my kwp2000 library and me7_95040 only uses kwp1281.
I'll PM you a new version with more detailed descriptions.

Well im failing miserably trying to read the 95040 from my ecu via OBD, i usually remove the ecu and clip the chip to read them but im determined to read with your software ArgDub, btw thanks for releasing this cheers.
Ive tried diffrent ports diffrent directorys removed instrument fuse but keep getting 'error 0x01'
the lead im using is a cheap serial vagcom lead with ftdi usb -232 converter, maybe this is the problem? not sure but this lead works fine any other time.. eg.. nef software/vagcom software etc..
as the audi a4 ecu's are a pain in the ass to remove i would really like to get this working.
one other thing to mention nefmoto software has trouble reading the ecu on this car, any other audi ive used nef on (5 diffrent audi a4's) it reads first time everytime (vagcom software works fine everytime with this car)
nefmoto connects to the car but keeps failing on read, i managed to get one full read out of approx 40 tries.
Audi A4 1.8T (163) AVANT 2003
ECU: 8E0909518AA
any idea's with your software ArgDub??
Thanks
Col
