We provide repairs for:

Fuel Injection Problems: Faults with fuel injectors lead to misfires, reduced fuel economy, trouble starting the engine, and white emissions. At Straightline Auto Repair, we can assist fuel injection repairs, ensuring everything works as intended.

Turbocharger Failure: The turbocharger is responsible for making your vehicle more efficient, channeling energy that would otherwise be lost back to the engine. The turbocharger can become damaged due to oil contamination, oil starvation, restricted airflow, and other causes that result in a loss of power and engine efficiency.

Clogged Diesel Particulate Filter (DPF): The DPF is responsible for catching exhaust ash and other contaminants, reducing diesel emissions. A process called "DPF regeneration" occurs under certain circumstances to burn the contaminants away. If DPF regeneration doesn't occur, it can cause a DPF blockage, resulting in poor engine performance. There can be many reasons behind why a DPF clogs. The team at Straightline Auto Repair will assist is identifying what repairs your diesel vehicle needs to continue functioning properly.

Engine Overheating: If your engine begins to overheat, it can cause serious damage. A coolant fluid leak, broken radiator hose, or clogged diesel particulate filter can all cause a diesel engine to overheat. Contact the team at Straightline Auto Repair for a diagnostic and repairs.

Bad Glow Plugs: Diesel engine glow plugs are responsible for heating incoming fuel and contributing to efficient fuel combustion, starting the engine. If you had a faulty or malfunctioning glow plug, it may result in trouble starting your vehicle or even failure to start it. Contact Straightline Auto Repair for glow plug replacement services.

Straightline Auto Repair can assist with a wide range of diesel services, from smoke and noise diagnostics to fuel injector repairs.

Remember, diesel engine maintenance is important to preserve the life and reliability of your vehicle. Check your owner’s manual to determine maintenance schedules.
