EGR & DPF Carbon Cleaning Sydney
Carbon and soot build up inside the EGR valve and Diesel Particulate Filter (DPF) on every modern diesel — especially on vehicles doing short trips, idling in traffic, or running cold most of the day. Once the build-up reaches a threshold, the engine drops into limp mode, throws check-engine and DPF warning lights, and starts losing fuel economy.
We clean the EGR and DPF in place, without removing parts. That keeps your seals and sensors intact, the labour bill low, and your vehicle off the road for hours instead of days. Every clean is paired with a full service: oil, oil filter, air filter, and fuel filter.
How It Works
- Submit Your Vehicle — tell us your rego and what it’s doing. No upfront price, every diesel is different.
- We Quote You — SMS or email back with a fixed price for your exact vehicle, usually within hours.
- Drop It Off — bring it to our Sydney workshop on the booked day. Pre-diagnostic scan runs first.
- Pick Up Same Day — carbon clean, full service, post-diagnostic report — back on the road same day.

Frequently Asked Questions
What is EGR and DPF cleaning?
EGR (Exhaust Gas Recirculation) valves and DPF (Diesel Particulate Filter) systems accumulate carbon and soot over time, especially on vehicles doing short trips or city driving. Cleaning removes this build-up, restoring engine performance and fuel economy without the cost of replacement parts.
Do you remove the DPF or EGR from the vehicle to clean it?
No. We clean both the DPF and EGR while they’re still installed in the vehicle. Other shops remove the parts to clean them off-car — that adds hours of labour, risks damaging seals and sensors, and means your vehicle is off the road longer.
Is cleaning better than replacing the EGR or DPF?
In most cases yes. New EGR valves and DPFs can cost several thousand dollars plus labour. Cleaning restores them to near-new condition at a fraction of the cost, provided the underlying components are not physically damaged or cracked.
How long does an EGR/DPF clean take?
A full EGR and DPF carbon clean typically takes 2-3 hours. We run diagnostics before and after so you can see the improvement.
What vehicles do you service?
We service most diesel passenger vehicles, 4WDs, utes, and light commercials with EGR and DPF systems. Tell us the make, model and year and we’ll confirm fit.

Common Questions About Pink Slip Inspections
How long is a pink slip valid in NSW?
A pink slip (eSafety check) is valid for six months from the date of inspection in New South Wales. You must complete a pink slip inspection every year if your vehicle is more than five years old to renew your registration with Service NSW.
How much does a pink slip cost?
The maximum inspection fee for a pink slip in NSW is set by Transport for NSW - currently $52 for cars and light vehicles, $29 for motorcycles, and $27-$41 for trailers (effective 1 July 2026). Mobile providers quote a total that includes the callout to your address; your exact price is confirmed when you request a quote. Caravans, trailers, and motorbikes have separate set pricing.
Can I drive on expired rego to get a pink slip?
Driving an unregistered vehicle in NSW is illegal and carries significant fines and demerit points. The safest option is to book a mobile pink slip inspector to come to your address, so you do not need to drive the vehicle until the registration is renewed with TfNSW.
What happens if I fail the pink slip inspection?
If your vehicle fails the eSafety check, you receive a list of repairs required to pass. Our inspector can advise on the most cost-effective workshop or mobile mechanic. Once repairs are complete, the re-inspection of the failed items is included at no additional charge within 14 days.
