The new flap valve (right) has an additional connection for the fresh air line.

Check the intake manifold flap valve N316 with Guided Fault Finding. If the flap valve is faulty, replace it with P/N 06H 906 283 B. This new valve has an additional connection 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.

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.

Example of routing the new fresh air line.
