Engine Warning Light for Audi
This bulletin applies to 2010-2011 Audi A3, A4, A5 and TT models, 2012 A3, A4, A5, A6, A7, Q5 and TT, 2014 A4, A5, A6, A7, Q5 and TT, 2015 A4, A5, A6, A7, Q3, Q5 and TT, and 2016 A4, A5, Q3 and Q5 vehicles equipped with a 2.0L engine.
The engine warning light may be on, accompanied by DTC P201500 (intake manifold runner position sensor/switch circuit range/performance) stored in the ECM. The likely cause is corrosion in the valve for intake manifold flap N316. If the flap valve N316 is faulty, replace it with P/N 06H 906 283 B. This new valve has an additional correction for the fresh air line.
Install the fresh air line with P/N 06H 133 583 F by first routing it along the cylinder head cover, then securing it with the included clips on the high pressure fuel line and activated charcoal filter cable. On in-line engines, loosen the securing bolt for the engine wiring harness between the second and third cylinder and secure the fresh air line with a bolt. On transverse engines, the M6 x 14 bolt with P/N N 107 732 01 (thread cutting) must be used in addition. Tighten the bolt at 9 Nm +/- 1 Nm. When routing the clean air line to the intake manifold flap valve, ensure that the clean air line is routed between the cylinder head cover and the vacuum unit lever for the intake manifold flap.
