M52 Timing Chain Tensioner

Hi All,

My M52 has a light timing chain rattle when cold which I think is a worn tensioner.

BMW have quoted a reasonable £26.95 for the piston, spring and crush washer, however I've read on the net that people fit whole uprated tensioner assemblies which the BMW parts guy seemed unaware of.

Does anyone have details of the whole assembly or even a part number? Any opinions on which one to use?

Thanks in advance.
