2008 Audi S6 Starts without pressing brake

Title says all. car starts without pressing brake. my key fob is dead so i use the iginiton swith to start it.
I could be wrong but isnt the brake supposed to be pressed to start the car? my porsche and jag required the brake to be pressed. I havent driven my audi in over a year so i forgot. im just hoping i dont have some kinda electrical F*** up. somebody plz help. lol

You are correct in thinking brake needs to be depressed to start engine. You need VCDS and must scan car. Perform autoscan and post results in this thread. More than likely (the Forum) can figure out the issue. The key not working should be addressed sooner than later as well…

My S6 (10/2006) also starts without the brake pedal being depressed. And it’s the same story with my dads A6 3.2 (01/2006).

No errors found in VCDS.

If i use my keyless start i have to press the brake. if i just use the key to start the car it starts without the brake…
