Engine OM642.961

Symptoms:
- Rough idling and loss of power
- Excessive smoke from exhaust (black or blue)
- Engine warning light illuminated
- Increased oil consumption
- Difficulty starting or misfires

Diagnosis:
- Check for clogged or faulty EGR valve causing rough running and smoke
- Inspect turbocharger for wear or failure leading to power loss and smoke
- Examine diesel particulate filter (DPF) for blockage, especially in GLK 320 CDI 4MATIC DPF models
- Test glow plugs and fuel injectors for proper operation to resolve starting issues and misfires
- Monitor oil condition and level to detect leaks or consumption problems

Fixes:
- Clean or replace the EGR valve to restore proper exhaust gas recirculation
- Repair or replace the turbocharger if worn or damaged
- Perform DPF regeneration or replace the filter if severely clogged
- Replace faulty glow plugs and fuel injectors to ensure efficient combustion
- Address oil leaks by replacing seals or gaskets; use recommended oil grade to reduce consumption

Prevention:
- Use high-quality diesel fuel and perform regular fuel system maintenance
- Follow scheduled oil changes with manufacturer-specified oil to protect engine components
- Avoid short trips that prevent DPF regeneration; drive at higher speeds periodically to burn off soot
- Regularly inspect and clean the EGR system to prevent clogging
- Monitor engine performance and address warning lights promptly to avoid severe damage
