application-specific features:
ME 7.5.1
ME 7.1

• 2.8L 5V V6
Several components have been added to more
accurately control boost pressures and regulate
engine torque. These include:
Features:
• Electronic Throttle Control
• Dual stage intake manifold with ECM actuated
• Electronic Throttle Control
Intake Manifold Tuning (IMT) Valve N156
– The throttle valve has the ability to operate
independently of driver input to maximize
efficiency
ME 7.1.1
• 2.5L 5-cylinder 4-V
• Turbocharger Recirculating Valve N249
• 3.2 VR6 (MY 2003 through MY 2006)
– Using an electrically operated solenoid valve
to control activation of the bypass valve allows
for more accurate control of charge pressure
bypass during throttle changes.
• W8
• 4.2L V8-5V
• W12
Features:
• Charge Air Pressure Sensor G31
• Electronic Throttle Control
– The Charge Air Pressure Sensor G31 provides
the ECM with exact data regarding manifold
absolute pressure.
• Dual stage intake manifold with ECM-actuated
Intake Manifold Tuning (IMT) Valve N156
• Dual ECMs (W12 only)
Refer to SSP 892303, The Phaeton
