Engine reliability and common problems:
The Mercedes-Benz OM642 is a 3.0-liter V6 diesel widely used in many models under the 3.0 CDI or 350 CDI designation. It is known for strong performance and good durability when maintained properly, and well-kept engines are capable of exceeding 500,000 km. At the same time, the unit has several characteristic weak points that tend to appear with age.One of the most well-known problems affects early engines produced before around 2010. The oil cooler sits deep in the valley of the V-engine, and the sealing gaskets eventually harden and begin to leak. When this happens, oil accumulates in the center of the engine block, and fixing the issue requires significant disassembly, making the repair relatively expensive.
The intake system can also cause trouble. The swirl flaps are operated by plastic linkages that may break over time, which leads to uneven engine operation, warning lights, and reduced power. The Bosch fuel system itself is generally efficient, but the piezo injectors are sensitive to fuel quality and are expensive to replace, often with little possibility of repair.
Turbocharger problems sometimes appear as mileage grows. Carbon deposits may cause the variable geometry mechanism to stick, and in some cases particles from a deteriorating exhaust manifold can damage the turbocharger. The engine is also quite sensitive to oil pressure. Issues with the oil pump, contaminated oil, or overheating can lead to bearing damage if lubrication becomes insufficient.
Additional concerns include the crankcase ventilation system, where the membrane inside the PCV valve may fail, as well as typical diesel emissions components such as the EGR valve and diesel particulate filter, which can become clogged over time.
Despite these weaknesses, the OM642 remains a respected engine when serviced correctly. It delivers strong performance, uses a durable double-row timing chain, and the cylinder heads are equipped with hydraulic lifters that reduce maintenance needs. With regular oil changes—preferably every 10,000 km or sooner—and good-quality fuel, it can be a long-lasting and capable diesel engine.
Overall, this engine can last around 360,000 to 600,000 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 | 400,000 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. |
