Rattling noise from intake manifold (plastic actuators) and engine mount wear causing vibrations
Often reported
A characteristic rattling noise comes from the intake manifold, typically appearing after 120-140,000 km, caused by plastic actuators or flaps inside the manifold. Additionally, engine mounts are reported to wear relatively early, especially after 60-100,000 km, causing vibrations during acceleration and at low revs.
