The Job
More Than a Standard Diesel Service
Diesel engines work differently to petrol, and a standard service doesn't always catch the issues specific to them. At SJB Mechanical, we offer diesel servicing in Cairns for utes, 4WDs and diesel passenger vehicles, backed by genuine diesel fault-finding experience. Our 4WD and DPF service is $300 plus GST and service items, covering the areas that tend to cause the most trouble on diesel engines.
Excess smoke, reduced power and rough running are common issues we see, and we'll explain what's causing them in plain English rather than technical jargon. For anything beyond routine servicing, our vehicle diagnostics can help track down the exact fault.
Call SJB Mechanical on 0447 162 060 to book your diesel service.

Questions
Questions we get asked
Excess smoke can be caused by issues such as a dirty air filter, injector problems or a blocked diesel particulate filter (DPF). The colour of the smoke, whether black, white or blue, can also point to different underlying causes.
Reduced power in a diesel engine is often linked to a clogged fuel filter, a failing turbocharger, or a DPF that needs regenerating or cleaning. Regular servicing helps catch these issues before they become more serious.
Diesel engines run on different fuel and emissions systems, including components like the DPF and high-pressure fuel injection, which need specific checks. A diesel service also focuses on areas like fuel and air filtration that work differently to a petrol engine.
