Common Diesel Breakdowns and What Causes Them

Even though diesel engines are vulnerable to certain types of wear and failure. The most frequent causes of roadside issues include

• Blocked Diesel Particulate Filters from frequent short trips or low-speed driving
• Fuel injector faults or pressure problems affecting performance and emissions
• Turbocharger failures due to oil starvation or overheating
• Electrical issues, such as flat batteries or faulty alternators, are preventing the engine from starting
• Sensor failures like MAP or crank sensors that trigger limp mode and reduce power output

These problems often develop silently until they suddenly stop your vehicle. Fast action is essential to avoid further damage.
