Technical Background
Perform 2 inspections before replacing the intake manifold.
Tip:
An ODIS intake manifold adaptation process must be performed after intake manifold replacement.
Inspection 1:
Vacuum line and vacuum tee restrictions (CCTA/CBFA).
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 DTC P2014,
P2015 faults.
Inspection 2:
Intake Manifold flap (BPY/CCTA/CBFA).
The intake manifold flap can separate internally and will not operate correctly with the regulator valve.
See Figure 1. and Figure 2. for an example of a damaged flap disassembled.

Production Solution
Improved intake manifold design.

Service
Procedure 1:
Vacuum line and vacuum tee restrictions.
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, Continue procedure 2 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.

Procedure 2:
Intake Manifold flap.
Check intake manifold flaps and if necessary replace intake manifold.
 Remove the engine cover. See Repair Group 10 Engine Assembly in Elsa.
 Move the carrier plate by hand in an axial direction (Figure 3, red arrow) to check if the carrier plate
can be pulled out.

Figure 3.

If the carrier plate can be pulled out, the flap has separated and the intake manifold must be replaced.
See Repair Group 24 Multiport Fuel Injection in Elsa.

If the carrier plate cannot be pulled out, perform the following procedure:
 Check the diagnostic limits of the flap with the ODIS tester.
 Under Motor, select Guided Functions (Figure 4).

If the adaptation is not successful, the flap stop is worn internally, the intake manifold also has to be
replaced. See Repair Group 24 Multiport Fuel Injection in Elsa.
Note:
The new intake manifold will come with a new style Solenoid Valve for Intake Manifold Flap -N316. Please reference TB 2047363 for installation of Clean Air Line.

Note:
If no carrier plate, vacuum line or vacuum tee related damage is identified, and the adaptation
passes, diagnose the faults using guided fault finding. This bulletin does not apply.
Note:
During intake manifold replacement, all fuel injector seals must be replaced, see Elsa for installation
instructions.
After performing Intake Manifold Replacement, add fuel additive G 001780M3 to the fuel tank. Also, refer
the customer to brochure 2020 VW Top Tier Fuel (VWTOPTIERMAY20) and explain the benefits of using
Top-Tier fuels as indicated in Technical Bulletin 2014815.
