As per title. I collect my 230 on Thursday, and have read and youtubed a lot about the exhaust sound on the 230. Does it have to be in any particular mode, and can the volume of sound be adjusted? Thanks :-)

The noise of the engine is amplified via a speaker in the plenum chamber.

It is louder in "sport" mode and the volume can be adjusted with ODIS or VCDS

The exhaust sound itself you will not hear. If you have the DSG, you will get the occasional pop. I have the manual and the exhaust is very quiet indeed!

Thanks folks :-)

Sound.

I thought the noise was simulated and not the amplified engine sound.

That correct, it's basically a small electric motor that's out of balance so vibrates when it spins.

It amplifies engine noise via a simulated means.

The 230 exhAust is actually different to the 220 but not sure how the actual note from outside cabin is different.

That does not make any sense.

Just what I was thinking. 

 

The sound generator has no connection to the engine what so ever.

I thought it sits in the intake manifold and amplifies the engine vibration/acoustic

I too, thought the 230 had a different exaust system to the 220. The sound can be heard outside the car and not just in the cabin, so I was told

to amplify is to make something greater, in this case louder.

The tsi engine produces very little actual engine noise so the sound generator simulates it.

There is no connection to the engines other than the generator being activated in correlation with its speed, there is no microphone so the noise is not transmitted, it is produced.

When I was a kid I simulated all the engine and the tyre skidding noises for my Dinky and Corgi cars.

Lips got sore after a while though.

It's exactly the same principal, albeit a little more "refined". The noise made is completely artificial.

An amplified simulated engine noise makes sense.

Wonder  if it will become a thing with Electric Vehicles.

 

When I lift the bonnet of my car the injectors sounds more like a manic knitting machine, not so nice. But from inside with a few revs it is not bad at all.

I believe the Toyota Prius has one for exactly that reason.

It's exactly the same principal, albeit a little more "refined". The noise made is completely synthetic.

 

"Refined" and "synthetic" are terms that should only be used for oil. Mine were totally natural and organic.

I can still do a pretty reasonable representation of a Merlin engined Spitfire performing a flypast! Of course very few Australians would recognise it as such.

 

Nearly wet myself when I heard and saw a Spitfire again at North Weald when visiting the UK last year.

Artificial was the term my brain wanted but my finger didn't agree.

We had a spitfire and a Lancaster bomber fly over a couple of weeks ago for the yanks weekend that goes on close to us. It was pretty special to see!

The 230 has a totally different exhaust system to the 220. It's more like a sports exhaust; if you want to call it that. There are more pops and bangs on the shift changes and are noticeable on the outside of the car. Plenty of YouTube vids regarding this.

I understand that an exhaust system can be tuned for a preferred timbre/frequency/volume but I thought that to get snap/crackle/pop you had to get some fuel being fed in on the overrun?

Really?

Is this a another system than the sound generator inside the dashboard?

Which all vRS's have if they have a vRSmode -button, even Diesel.

What I have described is the sound generator. Some models have also been known to play a low tone through the speakers in the passenger cabin to mimic engine noise too.

Ok.

So this has nothing to do with exterior sound coming from exhaust as I thought.

Just to make some fake sound inside to "sportier" atmosphere.
