Yes, noticed this on mine after regular daily use (when it's easier to spot patterns of events). When starting the car in the morning there doesn't appear to be a rattle - and the engine settles down quickly to idle just below 1000 rpm. When starting the car after a day at work, on a warm afternoon, the rattle is quite evident, disturbingly so - and the engine tries to idle at around 1200 rpm. However, I have now got into the habit of turning the ignition off straight away, waiting a few seconds, then re-starting the engine. The idle speed settles to below 1000 rpm (as it does in the morning)... and I then wait a couple of minutes before setting off for home. This seems to minimise the graunching noise that would occur if driving away 'quickly'.
Other than that, the car seems fine. It has had the known timing chain fix (apparently), but the engine is still a very noisy one and is lightly rattling as I park the car after a 30-mile journey.
Not sure if this is 'normal'... and quite worried that there's a long-term problem here.
