MAP Sensor on M119.981 (ME 1.0)?

Diagnostics yields DTC 0105 Manifold Absolute Pressure/Barometric Pressure Circuit but I can't find a MAP sensor in the Benz EPC, nor have I been able to locate such a sensor on the inlet manifold. Is the diagnostics pulling my leg or is there a very well hidden MAP sensor lurking about somewhere?

The car is a RHD 1998 W140 S420 and M119.981 is the engine with the direct ignition and fly-by-wire throttle controlled by Motronic V1.

The problem I am trying to fix is a consistent misfire that is particularly noticeable at idle when cold, but is present in all conditions.

Any info on this DTC or the MAP sensor in general would be of value.
