To keep people from having to track down the codes for the different diag modes. Note, none of these are credit to me, just putting them together in a useful place. Here is what I have found so far from various locations:

ipod diag:
* select audio aux input
* hold down hangup and down arrow for about 8 seconds
* release both buttons

Info found here: http://www.mercupgrades.com/iPod+Vol...rticle-45.html

console diag (disable traction control, reset service indicators, etc):
* turn key to position 1
* press and hold accept call button
* press and hold okay button
* after about 8 seconds, you should get into the diag mode
* release both buttons

Here is a video of that http://www.youtube.com/watch?v=3tLtaMPS46o

Anyone figure out the command system diag/engineer menu keys yet?

 

Hi, how does this work with keyless go??

I don't have my car yet, but a friend of mine has his and is wondering about it.

 

Push stop/start without your foot on the brake?

There's another thread with info for getting to the menu (where the disable ESP vid came from) that they specifically mentioned how it works with keyless go.

 

thanks

 

no problem, just glad it was useful. i kept having to hunt around to find the codes
