I have changed your topic because you never bothered to.

It is a ME7.1 ecu so it should be very very easy to get into bootmode if you follow the instructions. You never mentioned what you have tried and how you are doing bootmode without a bench cable.

It's primitive but it worked for my cluster coding when I had my jetta. Power and ignition switches, ecu plug, obdport with K line. I have tried grounding pin 24 to ecu board as well as bridging the 2 ports on the board that have been mentioned I've tried everywhere from 4 to 15 seconds holding the ground on then power on release ground then connect. Nothing has worked.  Sent from my Z917VL using Tapatalk |

in order.
ground boot pin, power on, wait 5-15 seconds, release ground on boot pin, tell galetto to read ecu. "boot mode inactive"
bridge the 2 pads, power on, wait, release the bridge, command galetto, "boot mode inactive"
from what ive been reading it can be driver compatibility issues. thats kind of where im at.
i have even tried ground pin 24, power on, wait, release ground, ign off (power on however) command galetto "boot mode inactive"

That should work. If it was driver problem I think you would get port open failure, as you said before. "boot mode inactive" is a good sign, it means galletto is talking to the cable correctly (I hope).

All I can suggest is to get another cable off of ebay (ftdi based) and hack galletto to see the correct serial num.

I did that with this one already. used m-prog to change the serial of my cable to match galetto (after saving its original serial)
I don't want to resort to buying an ecu off ebay but its that or mail this one off to someone and hope they can fix it all while not having a car to drive

also worth noting, nefmoto will not connect in boot mode or otherwise.
i can only think its not going into boot mode for some reason.

Or maybe your bench harness is missing a few things?

its wired exactly as the diagram says, only difference that i can tell is the k line from obd port splits to go to the cluster plug, and the ecu plug. there is nothing currently connected to the cluster plug though. would that cause issue?

Hi, i see a long time gone, but how you solve this problem, do you successfully cross-flashing 8D0907551 M-box file to 4Z7907551M? Because I'm thinking to do that on my 2002 Audi A6 6-speed 4B0907551AK but I'm afraid to brick the ecu. Thanks

if I had check summed the file properly im sure there would have been no issues.
I am currently running an s4 mbox so my abs/level controls are not happy.
