This used OEM BMW 8524835 Timing Chain Tensioner Guide Rail was removed from a donor vehicle. Also known as a guide rail or chain guide, it keeps the timing chain properly tensioned and aligned in the 0.6L 647CC I2 range-extender engine found in the BMW i3 and i3s. When this guide wears, you may hear rattling or slack in the timing chain. It must be coded to the vehicle on install.
