Diesel engine work at your yard or job site: hard starting, loss of power, smoke, rough running, injector and glow plug faults, fuel contamination and warning lights. Call 800-395-4908 with the unit and the symptom.
Diesel faults are diagnosed by reading the engine rather than swapping parts, and almost all of that reading can be done on site.
Prove It Before Replacing It
Injectors are expensive, so we prove which one is at fault before anything is replaced. Fuel trim and contribution data settle it.
Hours Matter As Much As Miles
Call 800-395-4908 with the engine, the mileage and the hours. Hours matter more than miles on a truck that spends time idling.
Read the codes and the live data, check fuel and air on the way in, pin down the cylinder or the circuit at fault, then repair it and prove the fault has cleared under load.
1
Hard starting when cold, power loss under load and smoke at idle point in three different directions. What the engine does and when it does it narrows the job before we set off.
2
Codes, injector contribution, rail pressure, boost and glow plug circuit readings. You see the figures the diagnosis rests on, not just a verdict.

Work carried out with quality parts, then run under load to confirm the fault has gone and nothing new has appeared. Written up for your records.
Stop-and-go traffic and long idling are the two conditions a modern diesel copes with worst, and Charlotte serves up plenty of both.
A diesel is at its best working steadily at temperature. Around Charlotte it rarely gets the chance: traffic funnels off I-77 and I-85 and crawls along US 74, and a truck doing deliveries or site work idles for a good part of the day. Soot loads the filter faster than light running can clear it, exhaust recirculation passages coke up, and a regeneration that never completes turns into a warning light and a loss of power. Fuel quality plays its part too, because water and debris sit in a tank that is topped up rather than run down.
Diesel work is one of the services under Truck Repair Shop Charlotte, so a fault that turns out to sit outside the engine stays with the same people. Where the problem is the running gear carrying the load rather than the engine pulling it, Trailer Repair Shop Charlotte covers the brakes, lights, bearings and couplings behind the truck.
The diesel calls that come in most often around Charlotte, and what each usually turns out to be.
Hard starting on the first cold morning of the year. Glow plugs or their control circuit, often failing quietly for months while warmer weather covered for them.
Power loss with a warning light after a lot of town work. Usually a filter that cannot complete a regeneration on short, slow runs rather than a failed component.
A rough idle that smooths out once warm. Commonly one injector out of balance. Contribution data identifies which cylinder before anything is removed.
Common diesel questions: what is possible on site, what causes filter warnings, and when a truck needs a heavy shop.
1
Full diagnosis, injectors and glow plugs on most engines, fuel filters and contamination, sensors, turbo pipework, cooling and charging faults. Internal engine work needs a shop, and we say so at the diagnosis stage.
2
Because short, slow journeys never let the engine complete a regeneration. We confirm whether that is all it is, or whether a sensor or a leak is preventing it, rather than clearing the light and leaving you to find out.
3
Yes, from diesel pickups through to work trucks and commercial units. Call 800-395-4908 with the engine and we will confirm before coming out.
4
Usually yes: draining, filters, lines and priming are all on-site work. If the contamination has reached the injectors or the pump we tell you what that means before any money is spent.
