What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint "Key Not Detected" message appears on the IC while driving even though the key is in the car and no doors have been opened. Cause Possible SW Remedy Confirm that the message is not due to the driver's door being opened and that the door latch is reading properly. For vehicles that do not have the above issues, SW is released for option code 805 ONLY. For all other vehicles, the SW is still in development. Current workaround is to ensure that the key is left on the antenna in the storage compartment.

Common questions

Is the LI80.35-P-080195 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
