Sensor faults, wiring and connector problems, starting and charging issues, and engine warning lights.

Repair scope, parts and timing depend on the fault. Our team keeps the conversation tied to your unit and the approved work.
Before you arrange service
Heavy-duty repair questions.
Do you work on Cascadia, Kenworth, Peterbilt and Volvo VNL trucks?
Yes. These are among the commercial trucks we work on. Call with the year, model, engine and repair concern so our team can discuss the specific work and scheduling.
Can you diagnose DEF, DPF, SCR and NOx sensor faults?
We offer commercial diesel aftertreatment and electrical diagnostics, including DEF, DPF, SCR and sensor-related concerns. A stored code does not establish which component needs replacement; testing determines the repair scope.
What if my truck is in derate?
Call with the truck details, warning message and whether it can be moved. We can discuss bringing it to our Pompano Beach shop. Do not assume the truck is safe to drive from a fault code alone; transport arrangements are the operator's responsibility.
Is this in-shop service or roadside assistance?
This page is for repairs at our Pompano Beach shop. Scheduled commercial-yard work may be available by arrangement. Call to confirm the job, location and timing; immediate roadside dispatch is not offered through this page.
Do you sell parts or offer emissions deletes?
We source and install parts as part of repair work. We do not operate a retail parts counter or offer emissions-delete or tuning services. Our aftertreatment work focuses on diagnosing and repairing the system.
Do you also repair medium-duty trucks and trailers?
Yes. Our broader commercial repair work includes medium-duty trucks, commercial trailers, buses and shuttles. Visit our commercial repair page or call to discuss your vehicle.
