Rattling noise when starting ignition, then gradually gets worse till its loud enough to hear inside the car with radio on. Sounds like roadworks being done with a drill. Revving engine stops it briefly. Only doe 35,000 miles. It has a timing chain so surely not nearly time to replace it?
It sounds like an issue with the timing chain tensioner!
Is the vehicle still under warranty? If so, take it to the dealer and have it checked out. If not, here's what I would recommend to try.
First, hopefully you have been maintaining the vehicle well, changing the oil as recommended and using Synthetic oil?
What I would try first is adding a can of engine flush to the engine, pick up a can at any parts store. Go ahead and pick up everything you will need to do an oil change too.
Ask for 10w30 Synthetic oil, (I know it calls for a lesser weight but trust me, any weight oils with multi-numbers is a seasonal oil, which means it can be used any time of the year). The heavier weight oil will give you or your engine more oil pressure which in turn will help by giving it more protection!
Plus, pick up a QT. bottle of Lucas Engine Oil Stabilizer while your at the parts store picking up the other stuff.
Hopefully you know how to change your own oil?
If not, you can go to a good shop and request for this to be done and they will do it for you.
If you do it yourself, you first want to use the engine flush and let the engine run with it in there for about 25-30 minutes, do not drive it just let it idle. You can rev the engine a little to help it work but do not rev it really hard.
After it has run for the allotted time, drain oil and replace oil filter, make sure to look at your old oil filter to make sure that the old gasket is on it and not stuck to the engine. If it is stuck to the engine you will need to remove it before putting on new oil filter or you will have a severe problem!
Most of the time the old gasket will come off with the old filter, I just always tell my mechanics to check and make sure! Add a little oil to the new oil filter gasket and screw new oil filter on hand tight and then tighten it with a oil filter wrench another 3/4 turn.
Then start by adding the Lucas Oil Stabilizer, it is thick like syrup so be careful not to spill it. Then add the oil but also be careful not to overfill the engine! I will usually add 4 qts. in total, so 1 qt. of Lucas and 3 qts. of oil, then crank the engine let it run about 30 seconds or so, shut it off and let it sit for about a minute and check it and add more oil as needed to top it off from there.
See if that stops the noise! That will be the cheapest way to try first!
If that does not work, I think the issue is going to be with the timing chain tensioner and it would have to be replaced, but I've had some luck in doing what I've said above as most of the tensioners use oil pressure from the engine to tighten the chain and the hole to prime the tensioner is really small so it doesn't take much to stop it up.
Hopefully the flush and then the thicker weight oil and Lucas will do the job, if it does, I would recommend to continue using it at each oil change! And, if you use these quick lube places, you will have to either bring your own Oil and Lucas Oil Stabilizer as they may not do as you ask!
Hope this helps

There are a lot of possiblities. Mass air flow sensor, o2 sensor. So this was hooked up to an OBD2 scanner and no codes came up? A good mechanic should be able to diagnose this problem in person. It is very hard to do over the internet but I will do my best to give you the most probable culprits. If you have a moment to accept and rate my solution on the original problem it would be greatly appreciated.
Thanks,

Your car is from 2006 how come it needs a timing belt ( do you drive 20K per year? ). What is wrong with the drive belt. The sound from belt is not a clicking noise.
Any way try to avoid that dealer. What a baloney.
When you start the car, open the hood try to identify where the noise comes from.
1-If it comes from the top engine, open your oil cap, to see if oils splattered from mechanical movements. Usually oil is not enough then it takes time to travel to the cam shaft and the lifters that why after making noise a while then the engine becomes quite since it gets lubricated. How long have you been from last oil changed?
2-If it comes from the front engine try to identify if it comes from Power steering or AC. Check Power-steering fluid to see it it needs filled up. Check this before starting the engine.
Try to turn on AC to see if the noise more or less so you can determine the AC clutch is bad.
Hope you can find the source for a good fix.

From a written description a rattle is not really possable to diagnose, is may be nothing to worry about but could be bad or dangerous, is there a fixya expert nearby to have a look before you land up with a big bill!
