Diesel Repair & Service in Auburn, CA

About Our Diesel Repair Service

Diesel engines use high-pressure fuel injection and compression ignition instead of spark plugs. Modern diesels also have complex emissions systems including DPF filters, DEF fluid injection, and EGR valves. These systems require specialized diagnostic tools and training. We service Ford Power Stroke, Chevrolet and GMC Duramax, RAM and Dodge Cummins, and Volkswagen TDI engines. Common diesel problems include clogged DPF filters from short-trip driving, failed fuel injectors, turbocharger boost leaks, and DEF system faults. We diagnose the root cause before replacing parts.

Why Choose Auto Analytx

We have the diagnostic tools and technical knowledge to work on modern diesel engines. Every diesel repair is backed by our 24-month / 24,000-mile warranty. If your DPF needs forced regeneration, we perform the procedure using factory procedures. If injectors are failing, we test each one to confirm which need replacement rather than guessing.

We provide upfront pricing before starting work. Most diesel diagnostics are completed the same day. If we need to order parts, we source them and schedule your repair within 1 to 3 days depending on availability.

Call us at (530) 392-4323 for an exact quote after we diagnose your vehicle.

What is a DPF filter and why does it clog?

The DPF filter traps soot from the exhaust to meet emissions standards. It clogs if you drive short distances frequently without letting the engine reach operating temperature. The truck needs highway driving to regenerate the filter by burning off soot. If the filter clogs completely, it must be cleaned or replaced.

Can you delete my emissions equipment?

No. Removing or disabling emissions equipment is illegal in California and voids your warranty. We diagnose and repair emissions systems to factory specifications. If your DPF or DEF system is causing problems, we fix the underlying issue rather than deleting the equipment.

Do you service Volkswagen TDI diesels?

Yes. We service Volkswagen TDI engines including Jetta, Passat, Golf, and Touareg models. We have the diagnostic tools and technical knowledge to work on both pre-2015 and post-emissions-fix TDI vehicles.
