Frequently Asked Questions

  • What services are included for diesel vehicles?

    Diesel servicing typically includes oil and filter changes, fuel system inspections, injector checks, turbo inspections, cooling system checks and diagnostic testing. Because diesel engines operate differently to petrol engines, regular servicing is essential to maintain performance, fuel efficiency and longevity.

  • Do 4x4 vehicles require different servicing?

    Yes, 4x4s often experience more strain due to off-road use, towing and heavy loads. This means additional checks are required for suspension, drivetrain components, differentials and underbody systems. Regular servicing helps ensure your 4x4 stays reliable both on and off the road.

  • What are common signs of diesel engine problems?

    Common signs include excessive smoke, loss of power, difficulty starting, unusual engine noise or poor fuel efficiency. These issues can be caused by problems with injectors, fuel systems, turbochargers or sensors, and should be checked as soon as possible to avoid further damage.
