VW Climatronic Diagnostic Codes
NOTE: This post has been back-dated to the year when I first published this information on my web page at istargazer.ca. This information applies to my 1999 VW Passat GLX which comes with the automatic climate control. (Stargazer, 28 December 2006)
The speedometer has a factory built-in error to show a speed faster than your actual speed. The Climatronic (automatic climate control) system includes a number of sensors that you can access through the diagnostic mode. To see your true speed in digital format press the following key combinations:

The speedometer has a factory built-in error to show a speed faster than your actual speed. The Climatronic (automatic climate control) system includes a number of sensors that you can access through the diagnostic mode. To see your true speed in digital format press the following key combinations:
- Press Fan Down, Temperature Colder, ECON at the same time.
- Use the temperature control buttons to cycle through the various channels to Channel 16.
- Press ECON to go back to normal. It goes back automatically when you restart the car.
This information was originally posted by Syncro Driver @ VWvortex forums:
There are a total of 45 diagnose channels numbered from 0 to 44. Some readouts represent a measured value and can't be altered--for example the amount of light that the sunshine-sensor on the dashboard measures. Others represent the actual adjustment and can be altered--for example the speed of the blower in 256 steps.Update: Posted 6 Mar 2001 by Syncro Driver @ www.ClubB5.com
It's not possible to make permanent adjustments so don't be afraid to try it at your own Climatronic. (Stargazer's Disclaimer: I am not responsible for any damage which may occur to your vehicle by attempting to use these techniques.)

"The channels that I know the meaning of are:Btw, an audi climatronic had 72 channels of which I do have a list. The 45 of VW must be a selection of this list (also a Hella system as far as I know) but I just don't know which. Is there anyone who knows them all?"
- 1 -- Interior temperature (sensor)
- 3 -- Sunlight sensor
- 7 -- Coolant temperature sensor
- 9 -- Blower speed (adjustable)
- 10 - Measured blower speed (sensor)
- 11 - Defog valve (adj. 0-255)
- 12 - Dashboard ventilation valve (adj. 0-255)
- 13 - Recirculation valve (adj. 0-255)
- 14 - Lower ventilation valve (adj. 0-255)
- 16 - Speed (sensor)
