[edit] 18438/P2006/008198 - Intake Manifold Runner Control Stuck Closed, Bank 1

[edit] Possible Symptoms

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

[edit] Possible Causes

  • Vacuum leak
  • Faulty Intake Manifold Runner Position Sensor1 (G336)
  • Intake Manifold Runner binding or sticking

[edit] Possible Solutions

  • Replace failed vacuum line
  • Check Intake Manifold Runner Position Sensor 1 (G336) and wiring, see repair manual.

[edit] Special Notes

  • When found in 2005 - 2008 Audi A4 and A6 with BKH 3.2L FSI engines, please see TSB 2019485/1 or 24-08-76 which discusses faulty vacuum hoses to the IMT (Intake Manifold Tuning) valve and IMR (Intake Manifold Runners).
    • If this fault is found after cylinder head and/or intake manifold removal repairs verify the vacuum operated Intake Manifold Runners do not have obstructed movement.
    • 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.
