Diesel Engine Diagnostics & Repair in Las Vegas

Modern diesel engines are complex systems controlled by sophisticated electronics. When something goes wrong, you need a technician who can read diagnostic codes and trace the actual problem, not just throw parts at it. MLM Truck & Trailer provides expert diesel engine diagnostics and repair for commercial trucks throughout the Las Vegas area, with mobile service available 24/7.

Our technicians use the Pro Link Edge by Snap On, a professional-grade diagnostic scanner compatible with all major commercial truck platforms, including Detroit Diesel, Cummins, PACCAR, Caterpillar, Navistar, and Hino. We perform diagnostics of check engine lights, body control modules, DPF cleaning, ABS systems, and exhaust systems (DPF and DEF). We read and interpret fault codes, perform live data analysis, and conduct component-level testing to identify the root cause before recommending repairs.

Our diesel engine repair capabilities include: fuel system diagnostics and repair (injectors, pumps, fuel lines, fuel system diagnosis, block testing), turbocharger testing and replacement (hoses, charge air coolers, exhaust inspections), EGR and DPF system service and repair (DPF cleaning, advanced exhaust diagnostics), DEF system diagnostics and service, cooling system repair (water pumps, thermostats, radiators, hoses, heater cores, freeze plugs, fittings, gaskets, leaks, cooling fans, fan clutches), oil system service (oil leaks, gaskets, seals, overheating diagnostics), air compressor diagnosis and replacement (governors, driers, valves, hoses and lines), electrical system repair (sensors, wiring, ECM, body control modules), driveline and transmission services (filters, fluid changes, clutches, transmission replacement, driveline and U-joint service, differential gaskets and PM services), and exhaust system repair and DPF service.

Many diesel engine repairs can be completed on-site, eliminating the need to tow your truck to a shop. Our mobile service trucks carry the diagnostic equipment and tools needed for the majority of engine work. For major overhauls requiring a shop environment, we provide honest assessments and coordinate logistics.

Diesel diagnostics and repair is available through our mobile truck repair service at your location. If your truck is down right now, our emergency roadside repair team can respond 24/7. For ongoing engine maintenance, ask about our fleet maintenance programs.
