Possible Symptoms
- MIL On
- Reduction of power at higher RPMs
Possible Causes
- Vacuum leak
- Faulty Intake Manifold Runner Position Sensor2 (G512)
- Intake Manifold Runner binding or sticking
Possible Solutions
- Replace failed vacuum line
- Check Intake Manifold Runner Position Sensor 2 (G512) 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 2019485/1 or 24-08-76.
- 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.
