18438/P2006/008198 - Intake Manifold Runner Control Stuck Closed, Bank 1
Possible Symptoms
- Malfunction Indicator Light (MIL) ON
- Reduction of power at higher RPMs
Possible Causes
- 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).
- Check Intake Manifold Runner Position Sensor 1 (G336) 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, 01-14-76 or TPI 2019485 https://static.nhtsa.gov/odi/tsbs/2014/SB-10065428-2280.pdf NHTSA
- If the ports on the intake manifold (which supply intake flap/ tuning valve solenoids) have insufficient vacuum, make sure the thermal door actuator 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
- Vacuum operated water pump may draw excessive vacuum causing intake manifold flaps to malfunction. Updated vacuum hose for water pump.
- 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
