Title: Need help with ecu coding that won't take.
Post by: Vintagewhr on January 09, 2016, 02:58:37 PM
So here is deal.  I purchased an ecu(sometime ago).  This is an L box that I was going to run in my b box 2000.  So I go to install everything and find out the coding on the L box is 06611.  I have everything done and it runs but I get the p1612 code and my transmission is like in dumb mode.   I have tried multiple times to code my ecu to 06651 with zero success.  Every time I try it just goes right back. I have tried the login.   Seems to do nothing.... I am stumped.  I need the experts and that's why I am here.... Any and all help is very much appreciated!!!

The only reasons the coding wouldn't stick on an ME7.x ecu:

1. The engine is running.
2. The coding is not supported.

Take a screenshot of the ecu number in vag-com, then go into nefmoto, and hit read ecu info. Screenshot that as well.

I can take a screenshot of the ecu in vcds.  I am currently not running nefmoto.  Was planning to start playing with it with this ecu.  What do you mean by the coding is not supported?  As in the number I am giving it doesn't exist???  Thanks for your help. Also below is the number on the ecu itself.

4B0 907 551 L

You are trying to put S4 coding in an A6 ecu.

4B0907551L supports the following coding variants:

06652
06752

The last digit is irrelevant to function, so you don't have to worry.

It is my understanding I can make an A6 ecu work right?  If so which one of those would I want for a 2000 s4 tip? 

I am on my way home and will be able to check the number in VCDS shortly.

Thanks!!!

The vag number in vcds is 8DO 907 551 A

Considering A is a manual ecu, it makes perfect sense that it won't accept tiptronic coding.

Flash it with a tiptronic file, then try your coding.

I don't have the ability to flash.  So does this mean I am hosed unless I can flash it??

I'm confused.  Install Nef, flash a file.  Done.

I can do that just haven't gotten that far yet.  where would I get said tiptronic file.   Or would I have to start flashing from my b box and start on a tune.  I was hoping to put that tune on so I had a jumping off point that was tuned.
