Start with the exact vehicle and symptoms
Warning messages and reduced power
Write down the exact dashboard message, when it appeared, and any change in operation. Follow the owner’s manual; do not clear codes or attempt a generic regeneration procedure to make a warning disappear.
Maintenance history
Bring oil, filter, and other service records. Diesel engines have specific fluid and maintenance requirements, and no single interval applies to every truck.
Vehicle fit and service scope
Provide engine details, dimensions, weight rating, body configuration, and the requested work. Confirm equipment requirements with Tony before dispatching a driver or arranging transport.
Have these details ready
- Year, make, model, engine, and fuel type
- Body dimensions, weight rating, and any commercial upfits
- Exact warning messages, mileage, and service records
- Whether the vehicle runs normally or needs transport
