Hidden Diagnostics

Thanks Matell and evolution42 for sharing the infos.

will too much gauge sweeping trick damage the electronic system or any other part in anyway?

Evolution42:
I can't get the gauge sweeping thing going. I followed your instructions, but nothing happened.. what's going on?

1. make sure you don't insert the key before beginning the procedure
2. make sure you press the little trip-meter reset button/dial , not the cruise control "RES" button
3. try the procedure as quick as you can (especially pressing the trip/reset button). however, try not to turn your headlights off/on off too fast, because it's not too good for the xenons

does it work now?

Does anyone know what the 'error 2' message means in the trip display when you do the gauge sweeping??

Thread revival.

I can't seem to engage this diagnostic mode anymore.
Does anyone have any ideas ? I follow instructions as listed but still doesnt work.

1. Turn the ignition switch off.
2. Press and hold both AUTO and DUAL buttons, and start the engine.
3. After the engine starts, release both buttons.
4. The audio-HVAC display will flash a sensor number, then value for the sensor.
5. To adavnce to the next sensor, press the rear window defogger button.
6. To cancel this mode, press AUTO, or turn off ignition.

:confused: That's very odd. Unless one of your buttons is stuffed I can't think of what may be wrong.

Every time I get in my car and start the engine by reflex I activate this diagnostic mode.

Wish I could offer more advice

Is it just me or is the hidden diagnostics a bit incorrect.

My trip computer display (MY2006) says 19c but the diagnostics says 20c...

yay

wtf ... Radar dials!

Nice one :D

"error2" - someone with the workshop cd - what is that?

If the word "Error 2" is indicated, there is a malfunction in the communication line between the gauge control module and the body-controller area network (B-CAN).

Nice~!! tried on my 06 euro :P
What does these 2 mean??
5. Evaporator outlet air temp (C).
9. Vent temp air out (C)
