Engine reliability and common problems:
Compared to their predecessors, B48 engines are more robust and less prone to major failures. They are well-suited for chip tuning, which can noticeably enhance performance and responsiveness without compromising reliability.Oil consumption, while significantly improved over earlier engines, may still appear closer to 100,000 km, often due to hardened valve stem seals. Another common issue is unstable idle or fault codes related to a lean mixture, typically caused by a faulty fuel tank ventilation valve — a relatively inexpensive part.
The cooling system is a known weak point. Coolant leaks may result from seal failures, cracks, thermostat or pump malfunctions, or general contamination. Symptoms include engine overheating, white smoke from the exhaust, poor coolant quality, visible leaks, warnings on the dashboard, and elevated temperature readings.
These engines are sensitive to fuel quality and oil change intervals. Cutting corners on maintenance often leads to costly repairs or even engine replacement.
At higher mileage, weaknesses may also include chain tensioners, the VANOS and Valvetronic systems, high-pressure fuel pumps, throttle actuators, and the turbocharger.
Overall, the B48 is a reliable and practical engine without inherent flaws. The mentioned issues tend to appear only under certain conditions and are not universal across all units.
Overall, this engine can last around 200,000 to 340,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
