Advanced Testing. Accurate Repairs. Long Term Performance.

All Insurance Autobody Works, we provide expert-level diesel engine diagnostics and repairs for all makes and models whether you're driving a work ute, delivery van, 4WD, or commercial fleet vehicle. Our Sydney-based workshop is fully equipped to handle the complexities of modern diesel systems, including common rail fuel systems, turbochargers, and DPF (Diesel Particulate Filter) servicing.

If you’ve noticed power loss, excess smoke, or your engine warning light is on, we’ll quickly pinpoint the issue and restore your diesel engine to peak performance.

What We Diagnose and Repair

Modern diesel engines are efficient, powerful, and built to last but when something goes wrong, it takes specialized knowledge and tools to fix it right. Our trained diesel technicians diagnose and repair:

  • Common rail injection system faults
  • Turbocharger boost loss or oil leaks
  • DPF blockages, regeneration failures, and cleaning
  • EGR (Exhaust Gas Recirculation) system issues
  • Fuel pressure loss and injector misfires
  • Sensor faults and engine control unit (ECU) errors

We use factory-level scan tools and testing equipment to deliver accurate results with no guesswork reducing repair time and saving you money.

Common Diesel Engine Symptoms

If you notice any of the following, your diesel engine may need diagnostics:

  • Engine warning or glow plug light
  • Black or white smoke from the exhaust
  • Hesitation, poor throttle response, or rough idling
  • Turbo whistle, whining, or boost loss
  • Excessive fuel consumption
  • Hard starts or long cranking

Early detection and repair can prevent further damage and extend the life of your vehicle.
