Pinpoint Test G: Exhaust Manifold & Turbocharger Leakage Test - Visual Inspection

WARNING: This page is about a different variant/trim than selected.

G1: EXHAUST MANIFOLD & TURBO LEAKAGE TEST - VISUAL INSPECTION

Check the fitment and integrity of the following components for leaks. Refer to: DIESEL PARTICULATE FILTER
Differential pressure sensor.
Pre-catalytic converter exhaust gas temperature sensor.
Heated Oxygen Sensor (HO2S).
DPF .
Post DPF exhaust gas temperature sensor.
Pre DPF exhaust gas temperature sensor.
Check the integrity and joints of the high pressure EGR valve to the exhaust manifold. REFER to: ENGINE EMISSION CONTROL

Check the fitment and integrity of the Exhaust Gas Pressure sensor for leaks. REFER to: ELECTRONIC ENGINE CONTROLS

NOTE:

Soot stains around the turbo actuator as shown in image 1 are normal. Soot mass around the turbo actuator arm is NOT an indication of a failure.
Excessive soot staining around the turbo as shown in image 2 is due to the turbo catalyst joint. Soot staining around the turbo joint is NOT a turbocharger failure - Do not replace turbocharger until proven faulty. Rectify the leak and retest.

Check the fitment and integrity of the turbocharger system joints and exhaust manifold for leaks.
Check to see if the turbocharger leakage is identified from the V-Band Clamp, if required repair with new one following Refer to: CATALYTIC CONVERTER TO TURBOCHARGER CLAMP
Is there any signs of a exhaust gas leak from the turbocharger?

Yes: Rectify the exhaust leak as required and clear DTC . Once the fault is rectified, start the engine and check for leaks. If the fault persists, continue to GO to PINPOINT TEST H ..

No: GO to PINPOINT TEST H .
