I have finally gotten the cable, power supply, and everything to work. I can get the nefmoto program to read/clear dtcs however it says it is unable to validate my memory layout

"Validation failed, ECU reports RequestUpload service is not supported. RequestUpload may have been disabled by aftermarket engine software"


i get this message, however the ecu is un-molested never modified. i am using the correct ecu definition file for my car (00 A6 2.7T).

"ME7 AM29F800BB" this is the one i am using.

Also when i check the flash to write I get the message
"Checking if flash matches succeeded
Flash memory does not match file to flash"

I was wondering if anyone can shed any light on this. I am in the military and going to deploy in these next couple weeks and want to get my car tuned before I go so my wife can enjoy it without it driving like shit on 630cc's/85mm/k04s on a stock ecu file..eek. thanks for any help.

Im going to continue to search but I have not read about any issues like this yet.

apr? its a stock ecu and im using nefmoto. i have a full version of ecux that also works but i dont need it for what im doing.

it is a k box a6 that i have kicking around from my wifes 00 a6 2.7t that i have been referencing...it is a Bosch MAF but if i flash it for an M-box shouldnt be an issue, no? my stock one is an AA and i get the "immobilizer" message when i try to bench flash it. so im going to try to flash that one in the car from what ive read that should fix the issue. since thats the ecu id wanna use anyway i just hope flashing it in the car would get rid of that immobilizer message, we will see today.

my aa box came off my 01.5 a6 6 speed, stock as shit. apr nothing ever used. i know aa's are also for a 02 tip s4 but they are different part numbers both ending in AA

i know not much proof by what some guy says but i have the same ecu.

anyway this is my stock ecu (the aa), i have a spare k box from my wifes 00 a6 6 speed i was trying to flash for my 01.5 a6 while i stiill have the AA in it. buttttttttt i cant get the k box to flash apparently on the bench, it says it cannot validate the memory layout (i tried 29F800BB and 29F800BT, which i read you use for a6/s4). so if i can get that to work thats fine and dandy.

so i tried to hook up the AA box (my stock untouched 01.5 ecu) on the bench and i am getting a immobilizer message from nefmoto saying it needs to be turned off. from what i read it needs to be put into boot mode, or it can be flashed with the ecu installed in the car to get around turning off the immobilizer.

i dont give a shit which one works, as long as i can flash either one of these to work. so imma try to flash AA box on the car now and see what happens.

Makes sense now. Glad it worked out for you.

Glad you got everything sorted.

Trial programs can prevent the ECU from being read, which prevents validating the memory layouts. It is possible your stock ECU came from Audi with ECU reading disabled for some reason. I have seen some VW R32 ECUs that appear to have had reading disabled by the factory.

Also, some ECUs are happier flashing with a slow init connect versus a fast init connect, or at different baud rates. The different init methods cause the ECU to use different communication settings internally, and some have better implementations than others in the different ECUs.

I've gotten "Validation failed, ECU reports RequestUpload service is not supported. RequestUpload may have been disabled by aftermarket engine software" a couple times.

You can still flash the ECU.

I got that with an APR tuned car. I proceeded to flash it anyways and worked without a hitch.

It even did it once with my own SW when I didn't do anything to disable anything. You can ignore it.
