The ExhaustGasRecircValve, on left side of IntakeManifold throat, is Vacuum actuated by the EGRSolenoid.

The EGRSolenoid, mounted near EGRValve, is a 12v~Vac Relay actuated by the PowerControlModul\PCM.

The DiffPresFlowElement allows calculation of EGRFlow from ExhaustManifold to EGRValve to IntakeManifold.

The DPFElement, mounted on 2 RiserHoses+Tubes, sends DiffPressure to the PCM for calculating EGRFlow.
