Before anyone gives me crap, I did do a search on Dyno mode before asking this question.

OK, now, I tried this sequence on my 2002 C32 and nothing happened after the 3 pushes of the odometer reset button. Are you referring to the post on the left side of the instrument pod or are you saying we have to somehow get into the trip odo reset in the computer before the SRS goes out? Anyway, I pushed the post 3 times before the SRS went out and no beep, no voltage meter. Does this programming work on later models only? Anyone?

The post of the left side is what I'm referring to. I'm not sure if it works on older model cars but it has been verified to work on SL65's, W211 E55's, and my C55. I read about another method of dyno mode by holding the reset down for about 45 seconds. Not sure if that works or not either on older models.

For the 2002 C32 there is a different procedure. From C32life

I don't know if anybody outside of the dealer is aware of this, but the traction control can be completely disabled simply by use of the steering wheel buttons. Here's the low-down-
1. To start, the key must be removed from the ignition.
2. Insert the key and turn to position 1.
3. Immediately press and hold the trip odometer reset button until the instrument cluster beeps. There is no visual message, only an audio beep. Be patient, this takes around 40 seconds.
4. Press the lower menu button (it looks like two sheets of paper, the one with the writing in the background behind the blank one)
5. Press the up arrow button.
6. Press the "+" sign to disable the Traction System (turn "ON" test mode)
7. Start the engine, the traction system is now disabled.
To return to normal, remove the key and restart the engine. The traction control warning should no longer be in the cluster. If it is, shut the engine off and remove the key again. Then insert the key and turn to position 1. Note that the DYNO test screen is displayed immediately. Push the "-" button to enable the traction system (turn "OFF" test mode)
NOTE: When you first turn the key to position 1, ESP DYNO Test screen pops up, then after 1-2 seconds it may disappear while faults are displayed. If you weren't fast enough in pressing the "-" button before codes were displayed, just wait until all codes cycle by, then the ESP DYNO Test screen will reappear.
No, this doesn't work for any car but the 203, before you ask.
Enjoy, and I'm not buying you new tires!

On cars equipped with Command, to enter the diagnostic screen
press and hold the following keys for about 8 seconds: Mute + 1 + 3

WTF r u talking about?
u said u drove around to get the tires hot, not the engine

Oh yeah, if nobody has mentioned this yet: If you put the car in dyno mode that means ABS is also disabled so be careful because we're not responsible if you're out actin' a fool. A 3600lb car will skid a long way when the wheels lock up.

Thanks Bif. That is exactly what I was looking for. I'll give it a try tomorrow.

AMG_55

yeah, thanks biff, im gonna try it too, might work on my car

i really really hope it doesnt thou b/c i will permanently drive it like that (unless it rains) if it does. for my cars and my sake i hope it doesnt work

ScottW911

OK, so I tried this diagnostic mode on my Comand system and I'm showing a few codes. Does anyone know where I can find a list of these codes cheap and easy?
