N47T Engine EGR Cooler Diagnosis and Determining the Condition of the Intake System
1.

Remove the engine cover and inspect the intake manifold and venturi pipe to the throttle for holes or
cracks.
Are there visible signs, on the intake
manifold and venturi pipe, of
overheating, similar to the illustration
(1)?
• YES – go to step 4.
• NO – continue with step 2.

2. Perform the air mass system test in ISTA (path Function Structure/Power train/Diesel fuel
electronics/Air mass/Air mass system test.
a. Select test: Charge group functional check. The tests checks the integrity of the charge air and
intake systems.
b. Listen and isolate any whistling in the charge air and intake systems while the test is running.
c. At the end of the test the throttle valve will close which causes the engine to shut off.
Did the engine shut down smoothly?
• YES- Check the results of the test plan and check the charge air circuit of the induction system
(air flow before the throttle valve).
o Repair as necessary.
o Do not continue with the rest of this procedure.
•

NO (engine stumbles or runs rough before shutting off) – there is a leak in the intake or EGR
system (air system after the throttle valve). Continue to Step 3.

3. Check the EGR system.
Is the EGR system leaking (external exhaust leak)?
• YES- repair as necessary.
o Repeat the test plan for the charge air system to confirm repairs.
o Do not continue with the rest of this procedure.
•

NO- continue to Step 4.

4. Check the intake manifold and venturi pipe for leaks.
Did you find any leaks?
NO – go to step 8.
YES – determine cause of leak.
A. If either component is damaged, continue to Step 5.
B. If leaks are found with no damage (leaking gaskets or sealing rings)

Repair as necessary.
Repeat the test plan for the charge air system to confirm repairs.
Do not continue with the rest of this procedure.

5. Remove the intake manifold (Refer to Repair Instruction RA 11 61 550 Removing and
installing/renewing intake plenum).
6. Check all swirl flaps for damage
or melted/missing parts (1).
Are any swirl flaps damaged?
YES- Continue to step 7.
NO - Go to step 8.
Note: N57T is pictured, N47T is similar.

7. Check compression of all cylinders (Step 6 = Yes only).
• Refer to Repair Instruction RA 11 00 540 Checking compression of all cylinders.
• The cylinders compression should be greater than 16 bar (232 psi).
• The compression test is to be performed after the engine has reached operating temperature.
• When performing the test, count the rotations of the engine crankshaft and apply the same rotations
to each other cylinder of the compression test. The industry standard is four (4) rotations per
cylinder.
• When comparing the values of all cylinders, the compression results should not vary by more than
2 bar or 29.01 psi between the cylinders.
Is compression performance of one or more cylinders out of range?
YES– Submit a TC case to the TC Engine group for further repair assistance. Continue with step 8 to
determine the cause of the damage to the intake system.
NO– continue to Step 8.

8. Remove the EGR valve and
check for jamming (valve is
normally sprung closed).
Is the EGR valve jammed or
stuck open?
YES- continue to step 10.
NO – go to Step 9.

9. Check the bypass flap on the EGR
cooler.
Is the flap binding?
YES- Replace the cooler (with EGR
valve.
NO – Reinstall the EGR valve and
continue to Step 11.

10. If the EGR valve is stuck open, check the valve for debris holding the valve open.
Is there debris jamming the valve open?
• YES (debris) - Replace the EGR cooler (with new EGR valve).
• NO (open, but no debris) - Continue to Step 11.
11. Check for faults after all repairs and re-run appropriate test plans to confirm diagnosis and repairs.
