Diesel Preventative & Factory-Recommended Maintenance

When it comes to your light-duty or medium-duty diesel vehicle, an ounce of maintenance is worth pounds of cure.

Instead of overpaying at the dealership, Wheeland’s Auto & Truck Service can perform all factory-recommended maintenance and additional preventative services to maximize the performance and longevity of your vehicle, such as:

Diesel Check Engine Light Repair

While most drivers dread the Check Engine Light, it’s your diesel’s way of letting you know that something is awry. If you remedy the issue expeditiously, you can prevent more expensive diesel repairs. In either case, the first step in remedying a Check Engine Light is a vehicle diagnostics. During the diagnostics, we will scan your vehicle’s computer to uncover the underlying issue, which may be:

NOX Sensors
Turbocharger Issues
Turbo Actuator
Diesel Particulate Filter (DPF)
Fuel Pressure Sensor
Service Emission
Glow Plug Failure
Cooling System Issues

Because of the potential culprits, it’s imperative to have your diesel truck inspected as soon as possible. Failure to do so can cause a potentially minor issue to snowball into much more expensive repairs.
