Sorry for the cross post but this is getting no play on the tech forum.
-------------

It seems that 2002 W203's could access diag mode - oil level in quarts/liters, ESP full off, etc...

by 1) holding reset button ~40 seconds, 2) hitting page down button on wheel.

This no longer works on 2003 - well on the coupe anyhow.

Any MB techs can share the new 'secret handshake' required to get into this mode?

Thanks
Peet
