Vehicles using 808 engine list:

Engine 808

Symptoms:
- Loss of power and reduced acceleration
- Excessive smoke from the exhaust, especially black or blue smoke
- Engine warning light (check engine) illumination
- Rough idling or stalling
- Increased fuel consumption

Diagnosis:
- Check for fault codes using an OBD-II scanner to identify specific sensor or system failures
- Inspect the diesel particulate filter (DPF) for clogging or regeneration issues, common in these engines
- Examine the turbocharger for signs of wear or failure, such as unusual noises or reduced boost pressure
- Test the fuel injection system, including injectors and high-pressure pump, for leaks or malfunction
- Verify the condition of the EGR (Exhaust Gas Recirculation) valve, which can become clogged with soot

Fixes:
- Perform a forced DPF regeneration or replace the DPF if severely clogged or damaged
- Clean or replace the EGR valve to restore proper exhaust gas flow and reduce emissions
- Repair or replace faulty fuel injectors or the high-pressure fuel pump to restore fuel delivery
- Service or replace the turbocharger if boost pressure is insufficient or mechanical failure is evident
- Reset the engine control unit (ECU) after repairs to clear fault codes and recalibrate sensors

Prevention:
- Use high-quality diesel fuel and adhere to recommended oil change intervals to reduce soot buildup
- Avoid frequent short trips that prevent the DPF from reaching regeneration temperature
- Regularly inspect and maintain the turbocharger and fuel system components
- Follow manufacturer guidelines for engine warm-up and cool-down procedures to prolong component life
- Schedule periodic diagnostic checks to detect early signs of component wear or failure
