MY15 Vanquish Start up Exhaust

[uglistix]

Hi all,

I've just bought a 2015 Vanquish and within 2 days I've already started to receive comments from neighbours about the start up noise at 5am! Before these comments become complaints, I wanted to do a bit of research and see if there's anything that can be done about the exhaust note on start up.

I've done a bit of reading on this forum and have found discussions relating to various fuses (22 and 15) for various Aston Martin's. However I think I'm right in saying that these topics were either for different models, or older Vanquishes, or more often than not were relating to owners wanting a louder noise throughout the rev range! Please point me in the right direction if I've missed some topic that would help here. Otherwise any suggestions would be welcome!

Now, don't get me wrong - as the driver of the car I LOVE the start up. So I'm looking for a solution that is switchable!

Thanks in advance for any advice!

John

the startup is loud, everybody asks me why do I rev it but I then point out its the sequence. somebody could have removed the "fuse" opening the baffles full time

Actually - the comments from the neighbours was exactly along those lines.... "hey - would you mind not revving the car when you start it up?". I did a demo to prove it wasn't me, but rather the start sequence - which left them rather bemused.

I don't think the fuse has been removed (although that's just a guess). A few seconds after start up the noise calms down considerably and general driving around town is surprisingly quiet (unless in Sports mode obviously!).

The DB11 has a quiet start mode which is useful is certain settings like school collections and early/late departures from home. So you could swap for a DB11?

Call Clive to see if he can help. He's a great guy.

but surely that just replaces the removal of the "fuse", wont help on a quieter startup

Excellent! I've fired an email off to Clive!

You could offer to pay for secondary double glazing in their bedroom? Just a thought...

They actually make it worse for themselves. They live in a converted barn next to my driveway and (apparently) the insulation is too good, which means that in summer they have to sleep with the windows wide open. So it's their fault right?

lol yup! I guess you could offer to pay for Air Con installing in their bedroom then so they don't need to open the windows?

Buy them a big box of ear plugs, much cheaper!

What a wonderful way to wake up each morning, they should pay you for being their alarm. Might help if you park so the exhaust points away from their windows

Two questions:

Where on God's earth are you going at 5am? Go back to bed!

Why are you driving your Aston to wherever you're going at 5am? Take a quiet daily driver!

Well, I like to drive my cars daily just after I've bought them to make sure I catch any niggles... but who knows - this might become my "daily driver" if I get too addicted! As for why 5am... well it could be worse... A couple of days I leave at 4am - but only when I'm cycling in (40miles each way!!).

My comments are on the assumption that Vanquish exhaust valves work in the same way as V8 etc.

As I think has already been said, whether your fuse 22 (or15) is In or out will not make any difference at start-up.
When the fuse is in, the exhaust valves close above about 1500 rpm, the re-open above about 4000 rpm.

You will need a 3 way switchable device, to enable you to close the valves during the 0 to 1500 rpm range.

I have a three way switch on my V12VR which was done by BR at Burghley a few years back. I prefer to call the three stealth, normal and loud! Living in the middle of nowhere never felt the need to start in stealth mode so never tried it I am afraid.

You have the sport button for noise reduction, no need to find the fuse, that's what the sport button does If you have set the default to "always on" which I certainly have, then you can push the key in and deactivate sport before putting foot on break and starting. Or just leave "sport always on" not operated.
