Known engine issues
OverheatingThis is a very hot engine with a thermostat point around 105-108°C, causing seals to harden quickly and oil leaks to appear. It is critical to monitor the cooling system and change oil as often as possible.
Oil consumptionDue to constant overheating, valve stem seals harden and piston rings stick, leading to oil consumption that increases with mileage. Oil passages may also coke, making it easier to buy a replacement engine.
Timing systemTiming chains last a long time, but the tensioner has a short lifespan. An updated tensioner now exists. As with all BMW engines, the Double VANOS units have limited service life.
