Service Interval Indicator

[Schod]

1995 A6, 1984cc ABK, petrol, manual gears, climate control.

I found this on the web:

This is the procedure to reset service and oil message:
on the instrument board we will call the left button #1 and the right one # 2.
-press button 2(right and switch on the ignition while keeping the button pressed,the display will show you "oil service
-release button 2 and PULL(not push) button one tll that you will se cleared oil service
-press again button 2 to display service message
-release button 2 and PULL button one until message is cleared
-switch off ignition key (http://www.automotivehelper.com/topic71405.htm)
-done


Turn off the ignition
Press and hold the button on the left side of the display while turning the ignition on
Service OIL will be displayed
Pull out the button on the right side of the display until the service prompt is cleared
The display should now read ---If the above procedure does not work, outlined below is an alternative procedure:

With the ignition off, push the right button
Turn the ignition on and then pull the left button
This should clear the warning messageI tried it but it did not work.
Does it refer to the USA vehichles?
