You probably have aftermarket software installed.
Flash to stock.

I have had this car ~ one year. What car feels like and last owners said it has no aftermarket software on it. What I have been logging with vag-com, highest maf what I have seen is ~130kg/s at full throttle. But it can be some expired trial tho.
Ok, I need to upload the original file from original section and try to flash it to the ECU.
Is it 800BB layout in my ECU since I have not yet opened it.

Before you flash and potentially brick your ECU make sure you have a backup plan. I strongly recommend a MPPS cable so you can recover the ECU if needed.

OK, thanks for the advice! How about if I brick my ECU with flash and I have another same chip, can I desolder bricked chip out of my ECU and solde a new one with original .bin file? Does it work that way...just wondering.

Not so fast !
If the ECU has a encrypt borad you can read it normally, but when you try to write it will stop in any point and brick the ECU.
I had an 2001 S3 Yesterday like this, open the ECU and there was the board, desolded the flash and resoldered again, tryed bootmode with Galetto and MPPS and could read, but not write anithing.
I finally desoldered again, programed externally and resoldered and job done.

If you have the tools to do so, sure, it will work if the software is exactly the same. But boot mode is much easier... |

I'm able to connect, and then read a little information, but I can't get much farther than this. I see .bin files posted by a few people, but I'm not sure if they've been able to do it through OBDII or if they're pulling their chips on this particular platform. It would be nice, as my intent is to decipher the SKC code.

The skc isn't stored in the main flash. It's in the eeprom (95040). Use argdubs tool to read it.

getting farther with the Nefmoto read, I just need to pick a memory layout, but I don't see a corresponding one to my ECU. Has anyone been able to successfully read through OBD connection on North American 2003 Audi A4's?
Still can't get ArgDub to work on this, application returns error:
"Initiating communication ... FAIL. (error=0x01)"

800bb, obd reading shouldn't be an issue as long as the ecu is installed in the car with a matching immobilizer.

I have read my 2003 A4 using nefmoto just fine, I pulled a BIN but not sure if what i have is correct or not. If someone wants to take a look i can post it. I got the security error as well and had to change this option to bypass it.
There are 2 check boxes, I dont recall what i did, but whatever yours is at, do the opposite.
under the KWP2000 Settings
last 2 check boxes
Security Use Extended Seed Request mine is checked
Security Support Special Key mine is checked.
as for memory map I used ME7 29F800BB.MemoryLayout.xml

thanks guys, I was able to get it working with a suggestion I received from "jimmcgee5" to drop the baud rate down after connection and that worked. http://nefariousmotorsports.com/forum/index.php?topic=3069.0title= |
