DIESEL TRUCK SERVICE

Diagnose the system before replacing expensive parts.

Modern diesel engines combine high-pressure fuel systems, turbocharging, emissions equipment and electronic controls. Accurate diagnosis matters.

01

Diesel Diagnostics

Scan data, fault codes and system testing help identify performance, starting and drivability concerns.

02

Fuel & Injector Systems

Fuel-pressure, injector and related fuel-delivery concerns can be tested and repaired.

03

Turbocharger Diagnosis

Boost concerns, turbocharger faults, leaks and related airflow problems are diagnosed.

04

EGR & DPF Systems

Diesel emissions and aftertreatment faults are diagnosed using proper testing procedures.

05

Cooling & Engine Systems

Diesel cooling-system, oil leak and engine-performance concerns can be inspected and repaired.

06

DIESEL DIAGNOSTICS

Loss of power can have more than one cause.

Fuel delivery, turbocharger performance, sensors, airflow, emissions systems and engine condition can produce similar symptoms. Testing helps identify the actual fault.

Scan data & fault codes Electronic system information provides a starting point for diagnosis.
Fuel-system testing Fuel pressure and injector operation can be evaluated when required.
Boost & airflow testing Turbocharger, intake and charge-air faults can contribute to poor performance.
DPF & emissions diagnosis Aftertreatment concerns require diagnosis rather than automatically replacing components.

COMMON DIESEL PROBLEMS

When should your diesel be checked?

Hard Starting

Glow-plug, fuel-pressure, injector, battery or other faults can contribute.

Loss of Power

Boost, fuel-delivery, sensor or emissions faults can reduce performance.

Black Smoke

Excessive black smoke can indicate over-fuelling, airflow or turbo-related problems.

White or Blue Smoke

Smoke colour and operating conditions can help narrow the diagnostic direction.

Check Engine Light

Modern diesel systems should be scanned and tested rather than diagnosed by symptoms alone.

DPF Warning

DPF warnings, regeneration problems or derate conditions should be properly diagnosed.

Diesel truck in reduced-power or derate mode?

Do not assume the DPF itself needs replacement. Sensor faults, exhaust leaks, EGR problems, failed regeneration or other conditions can cause aftertreatment warnings and reduced-power operation.
