dose the 2002 W208 has this function"dyno mode" ??? like what i found on the W209 fourm.

Turn It Off—All the Way Off!

For years we've complained about the butt-in behavior of the electronic stability programs in Mercedes-Benzes, which automatically intervene to shut down power and braking when they think your driving needs help. A dashboard switch suggests the program can be turned off, but it can't—it just kicks in at what it sees as a more intemperate level of driving on your part. We were convinced it simply could not be shut off.

Well, Benz lovers, we found a way.

Here's how. To start, turn the ignition key to the first accessory position, making sure the dash display shows the odometer. The SRS airbag light should be on. Press the trip odometer reset button three times rapidly before it goes off. If you do this right, a screen will appear showing a voltmeter. Then press the "up" arrow on the left side of the wheel twice to take you to the "ESP dynamometer test" screen. Using the plus (+) button on the right side of the wheel, select "on." And then start the car. Warnings will appear informing you that the ESP, ABS, and BAS (brake assist) aids are now turned off and you're on your own.

If you did it right, you've put the car in a mode intended for diagnostic testing on a rolling dynamometer—all electronic supervision is unplugged. Unhindered by techno-aids, the SLK's grip on the skidpad improved by 0.03 g compared with simply hitting the ESP switch on the dash. To return all the safety technology, scroll back to the dyno test screen and select "w/t. 15 off" with the minus (-) button. Shutting off all the electronic aids isn't easy, and that should tell you something. Owners are not generally privy to the dynamometer mode; therefore, we will continue to publish test numbers attained with the dashboard ESP switch turned off. We just thought you'd want to know.

 

wow, sweet trick...how about for a '98 w/o command???

 

I've tried in my 99 to no avail. I might just disconect the ESP module fuse itself if I am going to dyno. I dunno.

 

Thanks it works

 

Resurrecting an old but interesting thread...

Anyone currently on the boards ever really try this out with a 2000+ CLK or is this just an urban legend?

 

i'm pretty sure it actually works on 00+

 

To clarify, the CLK (W208) models do not have a "dyno Mode"

The CLK (W209) 2003 + models may....I don't know.

When my 2002 CLK55 was dynoed at the AMG Meet here in Atlanta last April, the tester simply turned off ESP. Wasn't perfect, but it worked.

 

I have had my 2002 W208 dynoed, and Chappy is correct.

 

on the w208 well ESP Button hit and ESP is off. no need go into dyno mode and this actually works really good, if not there is a electrical problem...

I know is a old thread but I still believe is a valuable info, specially because so many say they had a dyno but never add any test results from the dyno expect serious people,, sorry was not to offend anyone in this thread
