TECHNICAL BACKGROUND

Vacuum lines and "T" fittings may become clogged with debris from production or increasing mileage.

This debris may cause a restriction that could affect the intake manifold operation and cause the following P2014, P2015 faults.

PRODUCTION SOLUTION

N/A

SERVICE

Ensure correct intake manifold is installed on engine, refer to ETKA.

The intake manifold runner can be checked for proper operation using MVB 143 field 3.

The vehicle must be driven in order to place a load on the engine.

The engine RPM should be quickly increased to at least 3000 RPM and released. MVB 143 field 3 value should immediately change from 0% up to 100%.

If the values in field 3 instantly change to 100%, the hose and fittings are not restricted. If no restriction has been identified, this bulletin does not apply. Continue GFF based diagnosis.

If there is a restriction, the values in field 3 will slowly increase or not increase at all. Inspect vacuum lines leading to intake manifold, and fittings, for restrictions (twisted, kinked hoses or blockages caused by debris).

Reposition or clean as required.
