Derates, failed regens, warning lights, and recurring emissions faults can quickly sideline a working diesel. Max-Dieseltronics provides mobile DPF, DEF & SCR diagnostics and aftertreatment service in Oxnard, CA, with advanced troubleshooting focused on finding what’s causing the problem.
Diagnose The System Before Replacing The Parts
Aftertreatment systems are complex. The DPF, DEF delivery system, SCR system, EGR components, sensors, electronic controls, and diesel engine all have to work together.
When something goes wrong, the fault code is only part of the story.
Max-Dieseltronics specializes in advanced diesel diagnostics. We look at the conditions surrounding the fault and test the systems involved before determining what needs attention.
Our mobile aftertreatment capabilities include:
- DPF and regeneration diagnostics
- Failed or recurring regen troubleshooting
- DEF system diagnostics
- SCR system troubleshooting
- Derate diagnosis
- Aftertreatment fault-code analysis
- Live-data evaluation
- Sensor and electrical circuit testing
- EGR system diagnosis and component replacement
- Electrical and electronic diagnostics
- Engine performance troubleshooting
- Fuel system diagnostics
- Cooling system diagnosis
That deeper approach is particularly important when an aftertreatment problem keeps returning after codes have been cleared or components have already been replaced.
When An Emissions Problem Is Really An Engine Problem
A DPF or SCR fault doesn’t always begin in the aftertreatment system.
If the diesel engine isn’t operating correctly, the problem can show up downstream. Fuel delivery issues, injector problems, EGR faults, electronic problems, cooling concerns, and other engine conditions can affect aftertreatment performance.
This is where our engine expertise matters.
Max Dieseltronics doesn’t stop at emissions diagnostics. If troubleshooting uncovers an engine-related failure, we have the mechanical capabilities to address it.
Our services include high- and low-pressure fuel system repair, high-pressure fuel pump removal and installation, injector replacement, EGR repairs, water pumps, valve adjustments, leak repairs, cylinder head R&I, internal engine repairs, in-frame work, and complete diesel engine overhauls when appropriate.
The goal isn’t simply to make the warning disappear. It’s to identify and correct the problem behind it.

FAQs
Where Do You Provide DPF, DEF & SCR Diagnostics?
Max Dieseltronics provides mobile service throughout Oxnard, CA, and locations within approximately 50 miles. We diagnose applicable aftertreatment problems on diesel pickups, medium- and heavy-duty trucks, construction and off-highway equipment, and commercial or industrial diesel equipment.
Why Does My Diesel Keep Having Regen Problems?
Recurring regeneration problems can have several causes. Sensor faults, EGR problems, engine operating conditions, fuel-system concerns, electrical issues, or excessive soot loading may need investigation. Looking beyond the DPF itself can help identify why regeneration is repeatedly unsuccessful.
Can An Aftertreatment Problem Put My Diesel Into Derate?
Yes. Depending on the engine and fault, the control system may limit engine performance when certain emissions or aftertreatment conditions are detected. The fault information and operating data need to be diagnosed to determine what triggered the derate and what requires repair.

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!
