BMW B47 Engine Problems

The B47 is generally stronger than the N47, but EGR/DPF health, boost control, cooling condition, and service intervals still decide buyer risk.

Check a car before buyingSearch a fault codeCompare models

Common problems

  • EGR cooler problems and recall/campaign history.
  • DPF loading or frequent regeneration from short trips.
  • Boost leaks, actuator issues, or sensor-related limp mode.
  • Oil leaks and cooling-system residue as mileage rises.

Symptoms to take seriously

  • Limp mode, reduced power, smoke, or boost-pressure codes.
  • Coolant loss, EGR odor, or evidence of emissions-system work.
  • Rough idle, hesitation, or repeated DPF warnings.
  • Missing oil-change invoices or long intervals.

Checks before buying

Check BMW campaign/recall history for the EGR cooler.
Scan DPF soot/load, EGR command, boost pressure, and sensor data.
Inspect coolant level, EGR area, turbo hoses, and oil leak points.
Prefer cars with consistent oil service and regular longer drives.
