When your diesel is giving your issues, you need more than just a fault-code reader. We combine advanced diesel engine diagnostics, repair, and overhaul capabilities to find the cause, make the right repair, and handle major internal engine work when needed.

Advanced Diesel Engine Diagnostics In Oxnard, CA
Diagnostics are one of our strongest specialties. But diagnostics that's just the start.
When you experience a loss of power, hard start, excessive smoke, overheating problem, recurring fault, or abnormal engine operation, there can be several things at play. Instead of jumping straight to parts replacement, we troubleshoot the systems involved and work toward identifying the actual failure.
Our capabilities include:
- Advanced diesel engine diagnostics and troubleshooting
- Electrical and electronic diagnostics
- High- and low-pressure fuel system diagnostics
- High-pressure fuel pump diagnosis
- Fuel injector troubleshooting
- Engine oil, fuel, and coolant leak diagnosis
- Cooling system troubleshooting
- EGR and emissions-related diagnostics
- Engine performance and no-start diagnosis
- Hydraulic diagnostics on applicable equipment
Once we know what’s wrong, we can determine what it will take to put the engine right.
From Fuel System Repairs To Complete Overhauls
Max Dieseltronics isn’t a general automotive repair provider, and we don’t want you to mistake our diagnostic specialization for limited mechanical capability.
We do serious diesel engine work.
Our mobile engine repair capabilities include high-pressure fuel pump removal and installation, injector replacement, water pumps, EGR components, engine-mounted air compressors, leak repairs, and valve adjustments.
When the problem goes deeper, so do we.
Major Diesel Engine Repairs
For engines requiring substantial mechanical work, our capabilities extend to:
- Cylinder head removal and installation
- Internal engine repairs
- In-frame engine repairs
- Major engine component replacement
- Complete diesel engine overhauls when appropriate
That combination matters. The same diesel specialist who investigates your engine problem has the knowledge and capability to take the repair beyond basic diagnostics when the findings call for it.

Customer Testimonials
Can't say enough positive things: punctual, knowledgeable, hard-working, problem solver, positive attitude...it was a pleasure and we greatly appreciate having so many assets up and running!
I had an ECM on a caterpillar 3126 motor Motorhome which is very hard to get programed in California due to software costs and could not fine a mobil guy. I contacted Max who asked for some engine numbers and said would call back. the next day called back and came out Saturday morning pluged his system into my computer and within couple hours he fixed the issues. I found Max very smart and No BS. besides being a nice guy I trust him going forward and would recommend his services. i live in Ventura county
Great service and communication. We have used Max now for our Kubota Skidsteer and also our JLG Telehandler. He got us back up and running quick at our jobsite which was a major plus not having to load up and haul to a repair shop. Highly recommend their services!
