Does a BMW z4 have timing belt?

The BMW Z4 does not have a traditional timing belt. Instead, it uses a timing chain, which is much more durable and longer-lasting than a belt. The timing chain is located at the front of the engine and is driven by the crankshaft. It runs over the camshafts, which control the opening and closing of the valves. Because timing chains are more durable than belts, they do not need to be replaced as frequently, but may require more maintenance. For example, the timing chain tension should be checked regularly, and the tensioner may need to be replaced over time.
