BAD NEWS just tried it from a cold start and it's back, gonna ring audi now.Good News! Can you post a video clip of your new exhaust for us, I'm still in two minds as to go to Audi or not from the experiences people have received on here from Audi. Do you have a part number of any sort for the replacement part?
I've just recorded a video of mine after having the new back box with the same result as you have you heard anything back after sending them a video?For sure
Not losing any sleep over it just an observation made really. I’m just dreading the tips flaking, got everything crossed I will have a trouble free exhaust now.
I still have the rattle, just accepted that’s never going now unless the dealer offers anything from the video I have sent.

Bad times, I emailed the director of Audi UK to complain I had to take a day off work for it and initially the back box should of been replaced 2 weeks ago but when I took it in that time they hadn't got it but they failed to tell me that when they rang me the day before. The customer relations manager's gonna call me on Monday so I'll tell her the good news.Nothing at all, trying to build a good relationship with the dealer. He acknowledged the day after I sent it and said he would reply but that was Tuesday.
Will give him a week and then follow-up.
Got bigger problems at the moment anyway, the Turbo on my girlfriends Corsa is playing up and doesn’t kick in until very high in the Rev range... looks like a new turbo, cars are never easy.

First video just has the cat heating noise, cant hear any exhaust flap rattle. Cat heating wont be changed as its needed to meet emissions regs as Audi have confirmed. It is bad compared to other OEM's but when a free flowing exhaust is used along with the fueling and ign retardation needed for cat heat it does lead to noise. If car is cycled into dynamic engine mode before start the noise goes. It will always start in comfort unless forced into dynamic so that cat heat is used, it legally has to be the default engine mode. I work in engine calibration and cat heating is a neccessary evil to meet emissions regs.BAD NEWS just tried it from a cold start and it's back, gonna ring audi now.
This is the video
Someone on youtube took there's back for the same reason and it was fixed
It's a bit ***** how come the pfl didn't do it with the cat noise?First video just has the cat heating noise, cant hear any exhaust flap rattle.

Can hear exhaust flap rattle on second vid which is then gone with a new exhaust later on in the video.

Different model years have different emissions regs. FL is Euro6 which is not easy to achieve.It's a bit ***** how come the pfl didn't do it with the cat noise?
Thats why it always defaults to comfort with the cat heat mode enabled. The same as the emissions regs are only met with stop/start enabled hence it is always the default mode.Reading the posts and watching the videos I think that my exhaust valves ain't rattling. The cold start tapping is present until S mode or Dynamic is selected so I'm going to keep the original exhaust as it's not flaking.
The car still sounds **** with the ticking imo but I'll live with that for now as I can make it disappear but I'm not accepting the 'cold start' excuse by Audi.
If it was for emission reasons then surely you shouldn't be able to override it....
So why can it be overridden?Thats why it always defaults to comfort with the cat heat mode enabled. The same as the emissions regs are only met with stop/start enabled hence it is always the default mode.

Surely the cycle should be completed before an owner can override it..
And I saw the BM thread but why don't every new car, regardless of make or model, make the same racket?
I still think it's Turkish...
And that my friend is that.Good point. This is the problem with NEDC drive cycle based emissions regs. Stop/start is needed to meet them but then the driver can simply turn it off. I imagine this will change when the new regs come into effect for 2019my
Most current petrol engines run a cat heat cycle at start, the noise is bad on the RS3. As to why others don't make the same noise, there are many different variables such as base engine design, catalyst spec, exhaust spec etc etc.
The point I was trying to make is that I can never see Audi changing the engine calibration to stop the noise.
For me I accept that it's just a characteristic of the engine. A minor annoyance on what is a fantastic engine. I praise Audi for producing a 2.5L 5cyl 400bhp monster of an engine in a world where 2.0L 4cyl engines with no soul are the norm.

I’ve got a routine now...
Press start button to ignition on..
Cycle drive select or * button to select Dynamic
Foot on brake then start the car.
No rattle.
Think I will start this, I tested it and the rattle does go. I only put it into individual once it’s started anyway haha.
Only annoyance is that the drive select sometimes takes a bit of time to load up, on the MMI.
You don’t need to wait for the mmi though mr nutta.....
When you press the DS button just look at your centre RS dial and you’ll see the modes change.
Done before firing up the car there’s no rattle.
Having gone from a car with the rattle to a replacement exhaust (still rattled but was significantly quieter and of far poorer quality) to a new car with the rattle (but a lot louder) I would caution anyone thinking about getting the back box swapped out - it is unlikely to end well imo.

Yep I'm not getting mine changed out either, I too can live with a brief rattle on start up.
I've no sign of exhaust tip paint peeling and now have 2900 miles on the
clock. I reckon there must be a batch of exhausts with manufacturers variance in quality assurance.
One thing I do have though is the rusty hubs. It is pretty embarrassing for a 50k motor. On first service in Sep I'll get them to 'explain themselves' !
And lastly, my steering wheel does appear to be on straight and true.
All in all so far an epic motor !
Anyone else getting extremely rusty front and rear discs? I've only done 450 miles ***!

lol I've actually been driving it as much as possible, at least once a day if not more.
