The eccentric shaft is an important component of BMW's Valvetronic system, a form of variable valve lift control. If the teeth on the gear or the lobes have worn out, this can result in improper valve lift, decreased or abnormal performance, and even damage to cylinder head components. Replace your eccentric shaft with this high-quality part from OEM Febi to restore performance and eliminate valve lift issues without the marked-up price of a Genuine BMW eccentric shaft.
