If you’re in Jamisontown, South Penrith or anywhere along the Mulgoa Road corridor, the region’s diesel specialist is around the corner.
What We Do at Robertson Place
- Diesel Vehicle Servicing — Logbook servicing for all makes and models, warranty-safe.
- Fuel Injection & Common Rail — In-house testing and repair on cutting edge diesel testing equipment.
- Fuel Pumps & Turbochargers — Testing, reconditioning and replacement.

A Team You Can Trust
Most mechanical workshops send injector, pump and common rail work out to a specialist. We are that specialist. Having the testing equipment on site in Jamisontown means faster turnaround, no freight, and diagnosis based on what the components actually do on the test bench, not what a fault code suggests.
First Diesel Services Director Roger brings more than 40 years of diesel fuel injection and engine experience gained across England, New Zealand and Australia. The team he leads shares that standard: qualified diesel technicians doing precise, honest work, supported by admin staff who keep customers informed at every step.
I’ve had my injectors and pump rebuilt from these guys unbelievable work guys can’t recommend them enough Roger and the team are diesel wizards thankyou very much.

Took my Nav in needing some real care to keep it on the road. Delt with Lachlan, couldn’t have been more accommodating and genuine with his service from booking to the reminder call a day before to the thorough job he put into the service. Will be taking my other ute in asap without a doubt. You’re looking for a diesel machanic, look no further! Cheers legends
