Hi everyone, how's living with co-****-vid-19? I remember once long ago displaying and scrolling fault codes on my dashboard display (2005 W209 320 cabrio) using a "secret" procedure (kinda key-on-off-on-off-finger in the ear-tongue-out-press-up). Can't remember the "secret" procedure. Can anyone guide me to a relevant post? Any clue anyone? 1000 thanks
