New Guy, New to me Car, Old problem....
I bought a 08 Mini S with a dealer installed JCW package last week. Drove it and a GTI and there was no choice, the Mini was way more fun. Traded a 06 Corvette and don't regret the change. Now after learning about the inherent problems, I'm not second guessing the decision but facing the inevitable.
I took my wife out for supper. Heard a little rattle on cold start up. Drove 20 miles to dinner on the lake. After dinner on start up, a more pronounced rattle. No noise after startup however. So I figure I'll be on the phone first of the week searching for a competent shop to determine what's up. I'm in SouthWest Missouri with no local Mini dealer, (nearest are KC, St. Louis or Little Rock) there'a BMW dealer in Springfield and several independent shops but I'm not sure who has Mini experience. The car has 84K on it so if it is the dreaded "death rattle" with this many miles what all should I have done if it has to be down for repairs? Water pump? Vacuum pump? Thermostat? And how much should I budget for repairs?

I let the car set approximately 18 hours and then checked oil and viewed the tensioner, It has the dimple in the head so a sign of an upgrade. Oil was full. Hit the starter and no rattle. I let it sit another 5 hours and checked again, no rattle. The local family owned used car dealership where I bought it changed the oil but I don't know what kind they put in it. I'll call tomorrow and if necessary, change it over to a proper synthetic. Can that make a difference? If so, what to use, Mobile 1 or Castrol?

I use Mobil 1 0W 40, it was one of the alternate lubricants recommended by MINI until is wasn't rated LL-01, for long life oil. I change my oil every 5000 miles, so the LL-01 rating doesn't matter.
Be sure to use an OEM oil filter they don't cost any more than other brands, but some people have had problems with aftermarket oil filters.
This is where I got mine,

Be sure to check the oil weekly and keep the level at the top of the dipstick. My MINI uses about a quart every 5000 miles, some use more. They only hold about 4.5 quarts of oil, so it is important to keep it topped up.
MINIs have a weird water pump/ thermostat, unless you have a coolant leak at the waterpump, you will be OK.
If you have an automatic transmission, you should change the transmission fluid. They say it is "lifetime" fluid, but that is nonsense.
There are tutorials available here to show you how.

Follow Up.
I started the car this morning. There's a sound like a heat shield rattle for one second, then nothing but a smooth, quiet engine. I checked with the car lot that sold it to me, they changed oil with Castrol Synthetic 0-20 weight. Is that too thin? Is the tensioner pressure fed and leaking down resulting in the rattle until re-pressurized on start up? Should I try a new tensioner just to be on the safe side? Thanks again to all of you who responded with helpful suggestions so far.

They are both hydraulic and spring tensioned.
Try putting 5W-30 in it and see if that stops the noise.
Here are some interesting articles about the timing chain tensioner, there was a recall.

If you can't get a free one from the dealer.

Another follow up: I drained the 0-20 weight out and filled with 5-30 Castrol. 4.5 quarts. Double checked, its showing full. If I let it sit for 4-5 hours, upon start up I get a less than a second of rattle that sounds like a heat shield. If I shut it down and start it up again, no noise. Once started, I can rev it up, no noise. It doesn't have the same rattle noise I've heard on the sound files found on the net depicting the 'death rattle".
So learned ones, is this the start of the "death rattle" or likely something else, and if so, what?

Have you looked at the engine when it is making the sound? Maybe it is a heat shield.
My car sometimes make a short sound when starting cold, that's about 5% of the time, I don't worry about it. I have the original chain tensioner that came with the car new.
If you are still concerned, put the newest chain tensioner in your car, I've read that it has a stronger spring than the older tensioners.

The sound is so quick, and only happens on a cold start up, I haven't been able to be looking under the hood. I also wonder if it could be something with the AC compressor since we are in the midst of heat and humidity here in Missouri and once the system pressurizes upon start up, its good to go. I'll turn off the AC on the next cold start up to see if that has an impact.
I will go ahead and order a new tensioner for peace of mind.
