Hi everyone, I bought a 2001 audi tt quattro coupe, no manual and somehow I turned off the display that tells you how many liters per one hundred km you are getting, can anyone tell me how to turn it back on, it reads 11.4 all of the time now, would really love to turn it back on. Thanks

 

You control the OBC with the button on the bottom of the wiper control stalk. Press that and it should turn back on. Then a short push will cycle it to the next screen. A long push will turn it off. Not sure what you mean about the 11.4, when mine is off, the screen is blank.
