Diesel, DPF & EGR service Sunshine Coast
DPF warning light, limp mode or loss of power? We diagnose and fix diesel particulate filter, EGR, AdBlue and injector problems – European, 4WD and all makes.
Diesel services
DPF diagnosis & regeneration
DPF soot and ash levels checked with scan tools, forced regeneration where suitable, and the root cause found so it doesn’t clog again.
DPF cleaning or replacement
When regeneration isn’t enough, we quote cleaning or replacement – with photos and a fixed price.
EGR valve & cooler
Sticking or blocked EGR valves, coolers and intake carbon build-up diagnosed and repaired.
AdBlue / SCR faults
AdBlue warnings, countdown messages, NOx sensors and dosing problems diagnosed.
Injectors & fuel system
Rough running, smoke, hard starting – injector and fuel-pressure testing.
Diesel servicing
Correct low-ash oil, fuel filter and air filter to manufacturer specification – logbook stamped.
Why DPFs block up
Short trips
The DPF needs regular highway driving to burn off soot. Lots of short city trips stop regeneration finishing.
Underlying faults
Faulty sensors, EGR, injectors or turbo problems create extra soot – we fix the cause, not just the symptom.
Wrong oil
Diesels with a DPF need low-ash oil to specification – the wrong oil shortens DPF life.

Frequently asked questions
My DPF light is on – what should I do?
Often a 20–30 minute drive at steady highway speed lets the DPF regenerate. If the light stays on, flashes, or the car goes into limp mode, book a diagnostic – or call us first and we’ll tell you the safest way to get it to us.
Can a blocked DPF be cleaned?
Often yes. We check soot and ash levels first: some DPFs can be regenerated or cleaned; if the ash load is too high it needs replacing. We’ll show you the readings and quote.
What does the EGR valve do?
It recirculates some exhaust gas to reduce emissions. When it sticks with carbon you can get loss of power, rough idle, smoke or a warning light.
Do you work on diesel 4WDs and utes?
Yes – European diesels and all makes, including popular utes and 4WDs.
