timing belt or chain?

stupid question, I assume the F25 X3 uses timing chain instead of belt, right?

The timing belt on some cars is a toothed belt that cannot slip, should be quieter than a chain. However, all X3's have a chain.

A belt needs to be replaced and that can be a very costly affair. Chains are maintenance-free...
