So where is the MAP sensor located?

Na, I've got a boost problem:
Address 01 -------------------------------------------------------
Controller: 028 906 021 GL
Component: G00SG 1446
Coding: 00003
Shop #: WSC 06325
1 Faults Found:
00519 - Intake Manifold Pressure Sensor (G71)
28-00 - Short to B+
Readiness: N/A

I think the sensor in question is mounted on the pipe that runs from the I/C round the back of the engine between the engine and bulk head to the intake manifold, but I'm not 100% sure.
