The camshafts are responsible for opening and closing the valves in time with the movement of the pistons. Sometimes the lobes can become worn or scored, necessitating a replacement of the entire shaft. Performance options are also available with more aggressive cam profiles that allow increased lift and duration.
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.
