I need some help.
I have tried on my car and it is not working. what to do?

 

[QUATTRO_REP]

u use the actual up arrow, not the fan up + symbol. im guessin thats what ur doing cos i did the same thing! hold the re-circ button and hit the up arrow, then it should work.

I didn't realise these codes were secret.
The climate diagnostic display is mostly used for channel 17, which displays actual speed rather than optimistic speedo speed. Although a lot of people have GPS/SatNav for that these days.
