Timing chain

I have a 2005 120d. A mechanic recently told me that he could hear a ticking sound when the car was idling, with the oil cap taken off. he tells me that this sound is the timing chain wearing, and that it would need replacing. does this sound mean the chain is knackered, or is it normal to hear it with the cap off?
