2014 RS5 rattles when in idle

[D's RS5]

I am wondering if anybody has the same issue as I do...
There is a noticeable rattling noise coming from the driver side panel when the car is in idle. It goes away when I press the gas pedal. I am sure it is not one of the panels loose kind of thing. The car has a little over 14K on it. I took it to the dealer yesterday and basically they cannot tell me what's going on as the car is not throwing codes and they don't "have another car that they can compare side by side". They even tried to tell me that it could be a normal thing for the car. Sure. The car runs great of course right now but the rattling just bugs me too much...it could be a very serious issue. I googled around and it could be the timing chain/tensioner problem. Anybody has any ideas/suggestions/solutions?
addition: the rattling sounds like from the shield that goes over the manifold, more prominent on the driver side.

Do you have access to a lift? I've had several cases in my past where a strange rattle ended up being a catalytic converter going out. and in just about everyone one of those cases in my past, the rattle was only apparent at idle (various cars, never an RS5 specifically). I'd at least put it up in the air and lightly hit the cats with your fist to see if there's any signs of a cat that's breaking up. The reason why this comes to mind is because I had several mechanics that looked at my cars in these past situations, and the only person who could figure out where the problem was coming from was the guy at a local exhaust shop.

Even at 14k miles a cat can go back. Driving through cold puddles while the cats are hot can easily cause premature breakup of the inside material.

Did you track it down as to whether it comes from the engine bay or the interior? A rattle at idle isn't normal. I don't have any rattles going on like that. The timing chain issue was with the 4.2 V8 in the B6/7 S4. The RS5 4.2 V8 is a completely different engine based on the V10 from the R8. There haven't been documented timing chain issues since the B7. Audi addressed that issue in subsequent engine designs. The catalytic converters in these cars I believe are at the beginning of the exhaust way up in the engine bay and protected from the elements.

The Audi dealer lifted the car up yesterday, two of the mechanics said THEY THINK it is the timing chain tensioners, but they cannot warranty it.
I am sure that the rattle is from under the hood off of the engine...

They cannot warranty it? I would certainly hope it is covered under the warranty!

Unless the car is TD1.

Can't warranty a 14 rs5 with 14k miles...got to be TD1 or something.

Not TDI.... anyhow, we took it to another dealer who had a couple of RS5s in stock(the first dealer could not warranty it because "we don't have a car in stock so we can compare side by side", another words, they don't work on these cars much and have no clue) this time around the tech said there is definitely some abnormal noises, so we are just waiting to find out what the deal is. Will update when we find out more.

There is a TSB for a rattle sound accompanied with the slight bump felt shortly after coming to a stop. The remedy is an adjustment to the transmission programming. My 2013 suffers from this. I'm not sure if it affects 2014 or not, but, it's worth looking into.

does it make the noises when engaging gear from rolling out of idle? mine makes a rattling type noise when rolling out.....sounds like clutch/flywheel?

Update on the rattling noise:

after all these headaches, I thought it might be the exhaust manifold shield at first. I am a retired mechanic. Later I determined that was the AC pump compressor. This compressor has a shaft and a gear that will need to be replaced. This is not normal. I recently had my RS5 put in the shop for this to get it repaired. They had to remove my engine and transmission because the AC compressor and your power steering compressor is located on the side of the engine. My car is still under warranty so it was no cost to me. If you have this noise at an idle and raise your RPM up very little and it goes away, or turn on your AC unit and it goes away, most definitely you have this problem. Most Audi dealerships are not familiar with RS5s, I in fact did take my car to one dealership that told me it was normal. Being a retired mechanic, I knew that was not the case. Why would someone spend $90K on a car that makes rattling noise? You just need to find a dealership that works with RS5s.

-----now fixed :)

Thank you for the fix. I have the exact same noise from day one in my 2013.

What would you say is the danger of not fixing this? Just annoyance? I am out of warranty and don't wanna spend $3000 for Audi to fix this, haha.

I’ve also had this noise since day 1. I’ve taken it into the dealership 3 times and they haven’t been able to pinpoint the issue. They thought it was the transmission line rattling, so they insulated it. Then they thought it was the power steering line so they insulated it. None of the above fixed it, but it is an intermittent problem, and goes away when the RPMS are raised.

Hello! Did you solve the problem? Is it something serious or just annoying? Thank you
