Hey Everyone,

I get the following error when i had to do a full read of the ECU; Validation failed, ECU reports RequestUpload service is not supported. RequestUpload may have been disabled by aftermarket engine software.

I try it on two cars Audi A3 1.8TQ 1999 and Audi A4 1.8TQ 2002 both stock.

I have tried playing with the baud rates, tried slow and fast int(fast didnt work at all). I tried each memory layout with different baud rates. I can read ecu Info with no issues.

Current setup: Windows 7 x64, FT232R USB UART cable.

I wonder if there is a problem with the driver or a problem with the cable or software...

And a question:

If I can not Full Read the software, is that means 100% I will not be able to Full Write a new software? I am scared to try Full Write...

You claim they are stock, but are you sure?

Yes, I think they are original. I attached one of the files which I was able to read with MPPSv17.

Would you check if it's an original?

And would you give any opinion on this: If I can not Full Read the software, is that means 100% I will not be able to Full Write a new software?

If you are going to flash over them anyway, boot mode them to stock. I do not have every file floating around to check if your particular file is stock; get the stock file and compare it yourself using md5sum or just flash it to your ecu.
