Timing chain rattle – do I need to replace it?

The timing chain on my 2002 BMW 318i has begun to make a rattling noise. It has 146,000 miles on the clock and I rely on it for my daily travel. Should I replace the chain?
If the problem is just the tensioner you may be in luck, but I think the chain has stretched and I think you will have to replace it.
