  • Vacuum leak
  • Faulty Vacuum Solenoid (N316)
  • Faulty Intake Manifold Runner Position Sensor1 (G336)
  • Intake Manifold Runner binding or sticking

Possible Solutions

  • Replace failed vacuum lines or faulty vacuum solenoid (N316).

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)
    • 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.
  • When found in 2012-2016 Audi with 3.0 TFSI, please see TPI 2050329
  • When found in 1.4 TSI engine code BWK, check N316. This is a photo of the faulty 2 wire vacuum operated solenoid valve which was causing this DTC. Part number: 03C 906 283
