FAQs
Find answers to common questions about emissions diagnostics, emission system repairs, and check engine light faults.
When do I need a vehicle emission repair?
You may need a vehicle emission repair if your check engine light is on, fuel economy has dropped, or your vehicle is producing unusual exhaust emissions. An emissions diagnostic can measure system performance, identify the underlying fault and recommend the right repair before the problem worsens.
Can a mechanic diagnose emissions problems?
Yes. An experienced mechanic uses specialised diagnostic tools to identify faults within your vehicle's emission control system. Our car diagnostics service helps identify issues affecting petrol vehicles and recommends repairs that restore performance while helping meet Australian vehicle emission standards.
Can exhaust system problems affect emissions?
Yes. Faults in the exhaust system, catalytic converter, or oxygen sensors can increase emissions and reduce engine performance. Exhaust repairs may be required if damaged components are causing your vehicle to operate inefficiently or trigger a warning light.
Why has my check engine light come on?
A check engine light can indicate problems with the emission control system, the fuel system, or the engine management system. Driving with the wrong air-to-fuel mixture may increase carbon and nitrogen emissions, so it's best to have the fault diagnosed promptly before more serious repairs are required.
What happens if an emissions fault is left unrepaired?
Ignoring an emissions fault may cause your vehicle to perform poorly, consume more fuel or eventually fail an emissions inspection. Regular preventative maintenance helps identify developing issues early, reducing the risk of extensive repairs and keeping your vehicle running efficiently.
