The BMW m52 has a timing chain not a timing belt. there is no maintenance on the chain it is made for the life of the engine.
Inferior technology is only used on inferior cars. BMW stopped using belt timing in the early nineties. They all have chains.

After 1991 all BMW's use simplex or in this case, duplex timing CHAINS.
