Common Engine Fault Codes Related to Turbo and DPF Problems Modern diesel engines can store fault codes for boost pressure, airflow, EGR, DPF restriction, fuel pressure and oil pressure faults. These codes are useful for…
A turbocharger does not create its own oil supply. It depends entirely on the engine for clean oil under pressure, and that oil must also return freely back to the sump. If oil supply or…
Foreign particle ingress in turbochargers occurs when contaminants like dust or metal enter via the air intake or exhaust system. This can cause significant damage, including blade chipping and turbo failure. Proper maintenance, cleaning, and…
Exhaust Backpressure & Turbocharger Failure Backpressure is one of the most common root causes of repeated turbocharger failure. When exhaust gases cannot exit the engine efficiently, pressure builds in the exhaust manifold and turbine housing.…
Turbo Underboost: Causes, Symptoms & Diagnosis Turbo underboost occurs when the turbocharger cannot produce the required pressure commanded by the engine’s control unit. This results in low power, poor acceleration, limp mode, and common fault…
When a turbocharger’s compressor nut is missing, it’s a sign of serious internal failure rather than a minor issue. Causes include oil starvation, overheating, overspeeding, foreign object damage, improper repairs, airflow changes, and metal fatigue.…
