Hi,
some of you may already have these codes, however i thought for those who havent, id like to help...
this is the info i purchased off ebay,

Your Audi Climate Control Console has a diagnostic code that can enable you to access your digitally displayed speed, in kmph by pressing certain buttons in a certain manner.

To access your actual speed display, just follow these simple procedures:

1. Make sure that the car is started.
2. Press, and keep pressed the Re-circulation button, and then at the same time press the upward pointing arrow next to the re-circulation button.
3. Your Climate Control screen will change to a different mode displaying ā€˜1cā€™.
4. Use the Temperature Control (+) button to go up in sequence to display code ā€˜17ā€™. (or in some models it may be ā€™18ā€™)
5. Press the Re-circulation button again once and the code will be activated and it will begin to show the digital speed in kmph.
6. If you go past 99kmph, it does not show the hundred on some vehicles, but just shows the last two digits. Eg. For 127kmph, it will show 27.
7. To go back to your normal climate control mode, just press the Economy button, or switch the ignition off.

the following are also values you can access through the module, just select the number, i.e, 17c on climate control screen will be your digital speed, 27c will be your digital rev counter...

Accessing On-Board Diagnostic codes
Press and hold the recirculation button. Then press the manual flow control up arrow. You should see a 1c. Press the temperature up ("+") or down ("-") buttons to select a code number. Then press the recirculation button again. The value should display. Press the temperature up or down button again to display another code.
NOTE: Air Flow Motor (V 71) and Potentiometer (G 113) are not installed in USA/Canada vehicles. Disregard values displayed for these components.

hope ive been of some help....






I took out the caps in the title

 

That is a great info. Thank a lot for sharing...

I'm going to try today.

 

unfortunately it does not work on a 2002 a4 Q Tip.

 

haha it should.

 

are you serious? you paid for that?? ohh man try the search button next time

 

hi there, does this work for all Audi A4's??

I have a UK 2001 2.0SE but cant get the 1c to display...

also has anyone else ever had problems with the temp control on the climate control? if i select 18C on the panel it feels like 25c

if i select low its fine.


Regards

Del

 

Will these codes work on my 1997 A4??

 

go ahead and try it, it works with my 98

 

Does it work with B6s? Will it work with my Honda? Will it work with my Skateboard?

 

lmao!
