- A lot of problems are caused by a capricious direct injection system with piezo injectors;
- Also, Vanos phase regulators and the Valvetronic system regularly fail here;
- Many complaints on specialized forums are related to oil consumption and intake coking;
- A very modest resource in this engine has a timing chain, thermostat and pump.
