Command Engineering Mode
Does anyone know how to get into the Command Module Engineering mode for my 2011 SL550? There are videos on YouTube about how to unlock it for 2003 -2008 W230, also ML, and E Class models, but the electronics were changed for the W230 in 2009 and the unlock code also changed.
