Known engine issues
EGR valveMost problems of this engine are related to the EGR system, called AGR here. In early years, the valve could clog at 30,000 km and a recall campaign was even conducted. When it sticks open, overheating causes the intake manifold to crack.
Intake cloggingThe second most frequent service issue is clogging of the intake manifold and ports in the cylinder head, leading to loss of power and unstable engine operation. In severe cases, the intake swirl flaps may stick and break off.
Timing chain stretchThe chain timing drive on B-series engines differs little from N-series predecessors and may require attention before 200,000 km under very active use. There is already a cost-effective procedure to replace these chains without removing the engine.

Known issues and risks
Listed from most frequently reported, each with its source.
Timing chain tension/failure (N47)
Often reported

Timing chain
DPF and EGR clogging
Often reported
Frequent city driving in this 2.0 diesel engine can cause DPF clogging and EGR valve issues.
Exhaust Emissions
High-pressure pump/injector problems (CP4)
Often reported
BMW 2.0 diesel engines report failures or malfunctions of the high-pressure fuel pump (Bosch CP4); this can lead to pressure loss, heavy smoke, or no-start conditions.
Fuel System
Turbocharger failures/actuator or wastegate issues
Often reported
