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.
Turbo, injector and EGR problems (usage reports)
Often reported
In BMW 2.0 diesel engines derived from the N47/B47 family, turbo lag, turbo failures, injector or EGR valve abnormalities are reported to cause power loss, engine warning light illumination, or rough running.

Timing chain tension/wear (isolated cases)
Often reported
In some B47 2.0 diesel engines, although less common than the N47 predecessor, timing chain wear or tension issues may occur.
Timing chain
AdBlue consumption and warnings
Often reported
Multiple reports indicate anomalies or practical notes regarding AdBlue consumption: some users report variable range depending on tank capacity and vehicle usage, and more frequent refill requests than expected.
Exhaust Emissions
Clogged DPF (Diesel Particulate Filter)
Often reported
In many 2.0 diesel Euro6 engines in the Serie 1 F40, incomplete regenerations of the DPF can occur, especially with city or short-distance driving.
