I recently took my car to Cornell diesel , and I couldn’t be happier with the service I received. From the moment I walked in, ash and the staff were very professional, courteous, and clearly knowledgeable. They took the time to thoroughly explain the issues with my vehicle and provided a detailed estimate before starting any work.

The team worked efficiently, and my car was ready even earlier than expected. The quality of the work is top-notch; my car now runs smoother than it has in years! What impressed me the most was their honesty – they didn’t try to upsell unnecessary services, which is something I’ve encountered at other workshops.

The workshop itself was clean and well-organized, It’s clear they prioritize customer satisfaction and take pride in their work.

I highly recommend Cornell diesel to anyone looking for reliable and trustworthy car servicing. They’ve earned a loyal customer, and I’ll definitely be coming back for all my future maintenance needs!

If you’re in Sydney this is the place to bring your diesel, great team and a clean workshop with all the equipment. Honest quotes and updates on work being done.

Ash will bridge the gap between customer service and technical knowledge so you don’t have to worry about anything being lost in translation, you will be looked after and so will your vehicle.

I was struggling to find a good diesel mechanic I could rely on until I found Cornell’s Diesel Systems. I spoke with Ash and I couldn’t have been more happier with how I was treated. They listened to my concerns about my car and went above and beyond to make sure it was sorted for me. Ash and the team kept me updated and did so in a timely manner. Do yourself a favour and visit these guys if you’re struggling to find a reliable mechanic who will help YOU!

Thanks again team 🙏 A+++

Tom and Ash have ince again gone above and beyond!

Our pathfinder went in for new injectors, starter motor, and boost solenoid. The team worked magic to get this all done in time for our queensland road trip doing well to look after us.

The navara is booked in for new injectors and an intake clean.

Really happy custimers and highly recommend Cornell Diesel Systems!

Took my car for a diagnosis of smoke white in cold start and black smoke post warm up on mild acceleration. I try and research at best, but diesels are not very easy to isolate, and we need to trust process by elimination. Since I didn't have a lot of time, i was trying to get hold of a diesel specialist. In came Cornell Diesel Systems.

Ash was very patient in listening to my car's issues and booked me in. Post dropping off the car, he kept me informed of all the diagnosis they had done incl a compression test as the cost of changing few parts meant I was really asking the Q of should I keep this vehicle? Ash and the team did those tests and gave me confidence that my car was indeed in good condition, and it was just a matter of fact of regular wear and tear. It was a big ticket bill for my car, but I am hopeful of using my car for some overlanding trips! Post the fix all the all the issues that I mentioned have been addressed and my car runs smoothly. Thanks Ash for looking after my vehicle as if it was their own!

These folks also love their cars and are happy to hear from car enthusiast. I would recommend taking your diesel vehicle to these guys for a check without hesitation.

I was blowen away by the quality, they have an immaculate workshop and some of the latest testing equipment. Im super happy with the results and the professional service. I thought injector testing was a simple thing often not needed, I was wrong. The new injectors are complex little things that if not correct will result in running problems.The staff are super helpfull and tested my I ejectors and gave me a report on each one. Thanks guys

I recently had my engine replaced at a Cornell diesel for my 200 series Land Cruiser, and I must say that they did an outstanding job. From start to finish, their customer service was top-notch, leaving me extremely satisfied with my overall experience.

The staff at the workshop were friendly, knowledgeable, and always willing to address any concerns or questions I had throughout the process. They displayed a high level of professionalism and expertise, making me feel confident that my Land Cruiser was in good hands.

Not only did they complete the engine replacement efficiently, but the quality of their work exceeded my expectations. The new engine runs smoothly, and I haven't encountered any issues since the replacement. It's evident that the workshop's technicians are skilled and experienced in their craft.

In addition to their excellent workmanship, the workshop manager Ash also provided me with regular updates on the progress of the engine replacement. This level of communication kept me informed and assured me that my Land Cruiser was being taken care of properly.

Overall, I highly recommend this diesel automotive workshop for anyone in need of engine replacement and all services for their vehicles. The exceptional customer service, skilled technicians, and impressive attention to detail make them a standout choice. I am incredibly satisfied with their work and will definitely return for any future automotive needs.

Thank you to the entire team at Cornell diesel and a special thanks to the work shop manager Ash, Lorenzo and all the staff for going above and beyond to deliver exceptional service. Keep up the great work!

I took my car here for some diagnostic testing and after a few days they could not diagnose any faults. Eventually they suggested testing the injectors to which I agreed on. They had discovered that one of the injectors had failed their testing. They then replaced that said injector. All said and done and paid for mind you thousands of dollars later. Within minutes of driving my car home I noticed the car was driving much rougher than before I dropped my car off. I’m very disappointed in the whole experience and wish I hadn’t taken my car here. Some development needs to be done on properly diagnosing faults. I’d say they never road tested the car before, during or after during any of this said diagnostics.
