Key not detected warning
Happened twice to me since taking delivery. Only seems to happen if front passenger alights and then slams door a bit heavy handed. When i try to take off, the 'key not detected' warning comes up on the dash with the audible 'bong' . I can get the warning to disappear if i pull over and open the same slammed door and close it again. Its a weird one.. Anyone else had this?

Did you ever resolve the weird glitch? IMHO, the problem is a loose connection (or equivalent) in the passenger door wiring related to the 'lock/immobilizer system. In some models, there are up to three (or more) different levels or 'systems' that each interacts in different ways with the electronic key systems, some of which are permissive, some of which are no-go/alarm systems, and still others that are 'kill everything.' It will take an experienced,tech with an interest in figuring it out to search through the logic diagrams and find the fault tree. That you can 'un-do' the problem is good and will greatly assist the tech.
