I know, you don't want to admit it, that's OK, I understand. 
There is one on the market that claims it will not change the ECU of your computer and leaves no evidence of one being used and won't violate warranty issues. Since I have an A6, I am getting tired of the V4 mode and sound, just want constant V8 drivability. Manual sticks can have that constant V8 in the Sport and Track modes, so no issue with them.
I've done some reading on other car and truck forums touting the use of the disabler, most comments have been favorable.
