The timing chain in any vehicle can begin to stretch and rattle over time. This is a common issue, and though BMW says it is a lifetime part, most enthusiasts decide to change them. If you need only the timing chain instead of a kit, ECS Tuning has your replacement.

This guide is used to provide tension to the timing chain, but it wears over time. These plastic tensioners also become brittle with time and mileage, usually cracking and/or breaking completely. A common sign of worn timing chain components is noise from the timing chain area.
