Exhaust Repairs in Artarmon — Quieter, Cleaner, Safer

A damaged or worn exhaust system isn’t just noisy — it’s a safety issue. Exhaust gases contain carbon monoxide, and any leak can allow these gases to enter the cabin. At Brumby Motors in Artarmon, we inspect, repair and replace exhaust components on petrol and diesel vehicles of all makes, from simple muffler repairs to catalytic converter and DPF replacement.

Signs You Need Exhaust Attention

• Loud or unusual noise from underneath the car — rattling, hissing or roaring
• Strong exhaust smell inside the cabin
• Visible rust, holes or damage on the exhaust pipe or muffler
• Check engine light — often related to oxygen sensor or catalytic converter
• Excessive black or white smoke from the tailpipe
• Reduced fuel economy — a failing catalytic converter affects engine efficiency

DPF Issues — Diesel Vehicle Owners

Diesel Particulate Filters (DPF) trap soot from diesel exhaust gases. They periodically self-clean (regenerate) during highway driving. Vehicles used mainly for short city trips don’t regenerate properly, causing DPF blockage. Symptoms include a DPF warning light, reduced power and excessive fuel consumption. We diagnose DPF condition, perform forced regeneration where possible, and advise on cleaning or replacement when needed.

Frequently Asked Questions — Exhaust Repairs Artarmon

Q: How do I know if my exhaust is leaking?

A: An exhaust leak often makes a ticking or hissing sound that increases with engine revs, especially on cold start. You may also smell exhaust fumes inside the car with the windows down. A hoist inspection will confirm the location of any leak.

Q: My check engine light is on — could it be an exhaust issue?

A: Yes — oxygen sensor faults and catalytic converter efficiency codes are among the most common check engine triggers. We scan for the specific fault code and confirm the cause before recommending any repair.

Q: How long does a catalytic converter last?

A: Typically 150,000–200,000 km under normal conditions. Catalytic converters are damaged by misfires (raw fuel enters the converter), incorrect fuel, coolant leaks and physical impact. We’ll diagnose the cause of failure before replacing to prevent recurrence.

Q: Can a DPF be cleaned rather than replaced? A: Often yes. A forced regeneration or professional DPF cleaning can restore function if the filter is heavily sooted but not physically damaged. We’ll assess the DPF condition and recommend the most cost-effective solution.
