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 is a direct fit replacement for any broken or stretched chain. A great replacement to a damaged chain or one that may have been misplaced out of a timing belt kit.
