Engine reliability and common problems:
The Mercedes-Benz OM651 is a 1.8–2.2-liter diesel engine used in models such as the 180 CDI and 200 CDI. It is known for good efficiency and strong durability, and well-maintained engines often exceed 400,000–500,000 km. The design includes a cast-iron cylinder block, an aluminum 16-valve cylinder head with hydraulic lifters, and a combined timing drive that uses a chain together with gears and balance shafts. Simpler versions use an IHI variable-geometry turbocharger, while more powerful variants are equipped with a BorgWarner twin-turbo system. Despite its good reputation, the engine also has several well-known weaknesses.One of the most serious problems involves bearing damage caused by overheating of the engine oil. If the oil cooler becomes clogged, the oil temperature rises and its lubricating properties deteriorate, which can lead to oil starvation and bearing failure. Because of this, the oil cooler is often recommended to be cleaned or replaced preventively around every 100,000 km.
The timing chain itself is usually quite durable and may last up to 300,000 km, but the hydraulic chain tensioner can wear out much earlier. When this happens the chain begins to rattle, and replacing the tensioner can require significant labor. The fuel system has also caused trouble, particularly in early engines. Versions produced before 2011 used Delphi piezo injectors that were prone to failure and in some cases caused severe engine damage. Later engines switched to electromagnetic injectors, which proved more reliable.
Another known weak point is the plastic intake manifold. After high mileage it can crack, allowing air leaks and triggering engine fault codes. Injectors may also seize in the cylinder head due to carbon buildup, which can make removal extremely difficult during repairs.
The cooling system includes a complex thermostat and pump arrangement with a vacuum actuator. When this mechanism fails, the engine may take too long to warm up or, in some cases, run hotter than intended. Additional issues occasionally reported include oil leaks, as well as clogging of the EGR system and diesel particulate filter.
Despite these shortcomings, the OM651 remains a capable and long-lasting diesel engine when maintained carefully. Regular oil changes with high-quality oil, monitoring the oil cooler condition, and proper servicing of the fuel system are essential for ensuring long-term reliability.
Overall, this engine can last around 250,000 to 420,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.

| Camshaft drive | Timing chain Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more. More service info |
| Timing chain change interval | 250,000 km (recommended) Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur. |
| Fuel system | Common Rail Common rail fuel injection provides more engine power, is quieter, more environmentally friendly and offers better fuel economy, but is more expensive to maintain and repair. |
