Diesel truck problems can turn a scheduled route into expensive downtime. My Truck Repair Shop, operated by AGB Group Inc, provides heavy-duty diesel truck diagnostics and repair at 3236 US-701 Hwy in Conway, South Carolina. We serve owner-operators, local businesses and fleets from Conway and the Myrtle Beach area.
Diesel problems we diagnose
A warning light or fault code is the beginning of diagnosis, not the final answer. Similar symptoms can be caused by fuel delivery, air management, electrical supply, sensors, wiring, aftertreatment or mechanical conditions. We combine scan information with hands-on testing before recommending parts.
- Check-engine lights, fault codes and reduced-power complaints
- Hard-start, no-start and intermittent starting problems
- Low power, hesitation, rough running and unusual smoke
- Fuel, intake, boost and exhaust-system concerns
- Cooling-system and overheating complaints
- Oil or coolant leaks and related engine inspections
- Charging, battery and electrical faults that affect engine operation
- DEF, DPF, EGR and SCR warnings or derates
Diagnosis before parts replacement
Heavy-duty systems are connected. A low-voltage condition can create module faults; damaged wiring can imitate a failed sensor; an air leak can affect performance and aftertreatment. Our process is to document the complaint, review fault and operating data, inspect the related system and test likely causes. We then explain the repair path and parts availability.
This method does not promise that every fault will be simple, but it helps reduce guesswork. If additional disassembly or specialized work is needed, we tell you what the next step is before continuing.
Heavy-duty systems and supporting repairs
A diesel repair may involve more than the engine itself. At our Conway shop we also handle confirmed services such as batteries, filters, exhaust components, electrical troubleshooting, brakes, transmission concerns, air conditioning, tires, selected body and trim work and trailer repair. For emissions-related faults, visit our DEF, DPF and EGR diagnostics page. See the complete overview on our services page.
Why shop-based repair is often the faster choice
Roadside work has real limits: traffic, weather, safety, parts availability and access to equipment. If the truck can be moved safely, bringing it to our Conway facility usually gives the technician a better environment for testing and repair. Limited paid roadside diagnostics may be available by request, but we will recommend towing when that is more practical.
Information that helps us prepare
- Truck year, make, model and engine, if known
- Active warning lights and exact fault codes
- When the symptom started and whether it is constant
- Recent repairs, replaced parts or programming
- Current location and whether the truck can be driven safely
- Clear dashboard, component or leak photos when available

Frequently asked questions
Can you diagnose a truck that is in derate?
Yes, derate and aftertreatment complaints are among the systems we diagnose. The underlying cause must be tested before any regeneration or repair recommendation.
Do you replace batteries, filters and exhaust parts?
Yes. We service batteries, filters and supported exhaust components, including diagnosis of the condition that led to the failure.
Should I bring fault codes when I call?
Yes. Exact codes and dashboard photos help us prepare, although a code by itself does not prove which part has failed.
