Tell us about the job and we'll match it with up to 3 diesel mechanics in Sydney. Your contact details go only to businesses on a paid plan here, and after you send we tell you which businesses got them. Free, no obligation.
Diesel mechanics for diesel servicing and repairs, injectors and fuel systems, DPF cleaning and truck repairs. Mechanics Directory lists 191 diesel mechanics in Sydney. Listings show the services each business offers, and a rating where there is one.
Compare two or three. Ask whether they work on your make, and on light vehicles, trucks or machinery, whether they can come to you, and for a written quote for parts and labour. A business that is owner verified on Mechanics Directory has confirmed it runs the listing.
It depends on the vehicle or machine, the oil and filters it takes, and whether the injectors, turbo or DPF need work. Asking two or three local diesel mechanics for a written quote is the quickest way to see the going rate in Sydney.
Licensing depends on the work and the state. Modifications such as GVM upgrades need certifying under your state's rules, and outside Western Australia and the Northern Territory, modifications to heavy vehicles over 4.5 tonnes are regulated by the National Heavy Vehicle Regulator. In New South Wales, a business that repairs vehicles needs a motor vehicle repairer licence from NSW Fair Trading, and the people doing the work generally need a tradesperson certificate (some minor work is exempt). You can check a licence on the NSW Government's online licence check. In New South Wales, autogas (LPG) work is regulated under the Gas and Electricity (Consumer Safety) Regulation 2018; ask for the autogas licence. Listings marked "Credentials listed" show a licence, accreditation or membership on the business's profile. We don't check it, so confirm it with whoever issued it.
A diesel particulate filter (DPF) traps soot from the exhaust and burns it off on longer runs at highway speed. Lots of short trips can stop that happening, so the filter blocks and a warning light comes on. A diesel mechanic can check the filter and clean it or run a forced regeneration.
Some businesses are based in a nearby suburb but cover this area, including mobile mechanics and towing services that come to you. On suburb pages we list businesses based in the suburb first, then the ones that say they serve it.
Tell us about the job once. We match your request with up to 3 diesel mechanics near you. A business on a paid plan here gets it with your name and contact details and can contact you directly. A business on the free plan sees the job and your suburb but not your details, so it can't contact you unless it upgrades. A business that hasn't claimed its listing sees your request only once it claims. After you send, we tell you which applies to each business. It's free and there's no obligation.
