Title: How do I know which ECU file is for my car? Post by: Alpinab7 on November 26, 2014, 08:59:03 PM I am looking for a stock ECU file for a 2003 Audi RS6 (US version). I see several here but each has a different "software number". For example:
4d1907558 - 366304 (six digit number is the software number) 4d1907558 - 367724 Does it matter which one I use? I need to go back to stock software for a state inspection and they have been breaking my balls. I don't have the original file or any logs that show the software number. Thanks Title: Re: How do I know which ECU file is for my car? Post by: ddillenger on November 26, 2014, 09:01:58 PM I am looking for a stock ECU file for a 2003 Audi RS6 (US version).
