Where is the diagnostic menu?
What I'd like to know is how I can get in to the diagnostic menu on the dash... or does it even exist? You know, the one where you can see the engine oil level, enable dyno mode etc.
Searching for "diagnostic menu" gives me nothin under w220.
Just read the manual, there are many, many different menus for all kinds of information, too much to post them here
There is a diagnostic menu there, though you will have to guess what all the numbers mean. Some of them are obvious eg engine revs etc.

Make sure your MFD is displaying the MILES screen.
Turn Key to OFF
Turn Key to ON
Press the R button (right side of cluster) three times while the SRS light is on:

If you pressed the reset button 3 times while the SRS light is on and you were on the MILES screen, your display will display your voltage:

You can scroll through the various screens using the page up / page down controls on the left side of the steering wheel:

You'll see the car model, engine type, oil level (when running), software versions, VIN # and a bunch of other information:

Last page is the ESP DYNAMOMETER TEST screen:

Using the volume +/- controls on the right side of the steering wheel select ON

Start the car and several malfunctions will display since this will disable ESP, ABS, BAS, BPV and several other electronic controls in the car.
When you are done with dyno mode you MUST disable it... otherwise it will always be in dyno mode. Go to the ESP DYNAMOMETER menu and select W. KL15 OFF and then start the car.
It is the same thing that the stealerships use.
