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.

Over time, your engine timing components begin to wear out. Tensioners weaken, chains can stretch, and timing chain guides can wear down. All of these lead to the possibility of the timing chain jumping teeth on the sprockets, causing your timing to shift. This could result in rough idle and reduced engine power, or even complete engine failure. Prevent damage to your engine with new timing components, such as this IWIS timing chain tensioner. Note, we recommend replacing timing components every 100K miles, or sooner, depending on the condition of the timing components.
