Listed from most frequently reported, each with its source.
Some examples report faults related to the cooling circuit: stuck thermostat, water pump, or related component failure. These issues can cause abnormal engine temperature management, diagnostic warnings, and in severe cases, overheating.
Cooling
Direct injection V6 engines may experience carbon buildup on intake valves and ports over time. Typical symptoms include rough idle, lack of response at high RPM, increased fuel consumption, and the need for periodic cleaning (e.g., walnut blasting).
Engine Internal
The PCV (crankcase ventilation) circuit can fail or become deformed, leading to excessive crankcase pressure, oil entering the intake manifold, increased oil consumption, deposit buildup, and contributing to electrical issues.
Engine Internal
The V6 3.5 engine (M276) in the E 300 may experience timing chain tension and rattling noise, especially when cold. The issue also affects belt tensioners, guides, and camshaft phasers. If neglected, it can worsen timing and cause further damage.
