// Our Specialities
The things we do better than anyone local
Most workshops send this work away. We do it in-house at Leighton Place with the tooling and software to back it up.
ECU Flash Tuning & Remapping
Custom ECU flash tuning, remapping, module coding and adaptations for power, economy and driveability.
Learn more 02EGR Solutions
Carbon-choked EGR valves, coolers and intake manifolds cleaned, repaired, replaced or blanked.

AdBlue warnings, countdowns and no-start lockouts sorted — injector, pump, heater, tank sensor and NOx faults diagnosed and repaired properly.
Learn more 05DTC Fault Code Solutions

What you can expect
Honest advice
We tell you what needs doing now, what can wait, and what doesn't need doing at all. Quality over quantity, every time.
We go deep in diagnostics
Parts cannon repairs cost you money and don't fix the fault. We test, measure and prove the cause before we quote.
Specialist capability
DPF, EGR, AdBlue, diesel and ECU work handled in-house — cleaning, repair, replacement, remapping and fault-code solutions.
Local and independent
No franchise scripts, no upsell targets. Just a Hornsby workshop that wants to see you again next service.
// About the Workshop
A Hornsby institution, still run by hand
Owner and head mechanic Jason has spent over 20 years in the trade. Taking over from the late Phillip Lim — his mentor and the workshop's founder — Jason has kept the same long-standing customers coming back to Leighton Place.
We value doing the job properly over doing it fast. Every vehicle gets diagnosed before it gets quoted, and nothing happens without your approval. We service all makes and models, from work utes and 4WDs to European passenger cars.
// Everything Else
Full mechanical servicing
We're still your local general mechanic — logbook servicing, pink slips, brakes, tyres and everything in between.
Logbook Servicing
Manufacturer-schedule servicing on all makes and models that keeps your new-car warranty intact.
Pink Slips & Rego Checks
NSW e-Safety (pink slip) inspections and rego renewal checks for light vehicles.
Brakes & Suspension
Pads, rotors, fluid, shocks, bushes and steering — inspected and repaired to spec.

// FAQ
Straight answers
My DPF light keeps coming on — what are my options? +
We test the filter and the systems around it, then talk you through the options: a deep clean and regeneration, a replacement filter, or a software solution. A blocked DPF is usually a symptom of something else — leaking injectors, a tired turbo, a faulty sensor or a lot of short trips — so we fix that too.
Do you do ECU flash tuning and remapping? +
Yes. Custom flash tuning and remapping for power, torque, towing and fuel economy, plus manufacturer reflashes, module coding, immobiliser and key programming, and fault-code solutions.
Do you work on all makes and models? +
Yes — Japanese, European, American and Australian makes, from work utes and 4WDs to European passenger cars. We specialise in modern common-rail diesels.
Will servicing here void my new-car warranty? +
No. Under Australian Consumer Law you can have your vehicle serviced by any qualified workshop. We service to the manufacturer's schedule with the correct parts and fluids and stamp your logbook.
Do you handle insurance and warranty repairs? +
Yes. We deal directly with the major insurers and extended-warranty providers, prepare the reports they need and manage the claim through to completion.
Do you do pink slips? +
Yes — NSW e-Safety inspections for light vehicles, plus advice on anything that needs rectifying before renewal.
