18502/P2070/008304 - Intake Manifold Tuning Valve (Bank 1): Stuck Open

Possible Symptoms

  • Malfunction Indicator Light (MIL) ON
  • Reduction of power at higher RPMs

Possible Causes

  • Vacuum leak
  • Faulty Intake Manifold Tuning (IMT) Valve Position Sensor (G513)
  • Intake Manifold Runner binding or sticking

Possible Solutions

  • Replace failed vacuum line
  • Check Intake Manifold Tuning (IMT) Valve Position Sensor (G513) and wiring, see repair manual.

Special Notes

  • When found in 2005 - 2008 Audi A4 and A6 with BKH 3.2L FSI engines, please see TSB 24-08-76 (TPI 2019485/1)
    • If the ports on the intake manifold (which supply intake flap/ tuning valve solenoids) have insufficient vacuum, make sure the solenoid under the air filter housing isn't broken/leaking. This can cause a leak in the circuit connected to the mechanical vacuum pump on the right cylinder head resulting in P2006,P2007 and P2070.
