The Fuse by-pass tom foolery for V8 Vantage?

[TonyHetherington]

Hi everyone

Please forgive me as I'm certain this is a really common question - however, there's no FAQ's or WIKIs and the search function is broken at the moment.

A colleague's friend has just bought an '07 V8 and I mentioned that I recall a way to keep the bypass valve open the whole time on the active exhaust.

Is it just a case of pulling out a fuse, or is there more to it than that? If there's a thread with all the info I'd be much appreciated of a link to it (as I say, the search function is broken at the moment)

Thanks very much
Tony

Just pull the relevant fuse in the boot.

The relevant fuse is documented in the handbook

Fuse 22 in the rear offside boot compartment;)

It's really that simple and there's no side affects?

Fan-tastic

edit; oh, and I assume that to make it work again you just plug is straight back in?

Remove the parcel shelf from the boot to get the full benefit of all that exhaust noise coming into the cabin

or buy a Roadster (and pull fuse 22)

Yes, Fuse 22 but you'll need a Porsche on hand to remove it (ask Pikey and Greg).

Took your advice but opted instead for a Tequila Sunrise (small vodka and extra orange juice 'natch !) complete with umbrella and sparkler - but point taken anyway !!

The actual reason I did it was that there was some "talk" on AMOC ages ago that removing fuse 22 would eventually cause the valve to permanently jam in the open position with associated £millions of cost to replace it. Admittedly the posters were from the other side of the pond IIRC.

My luck wih things mechanical ('tho not the V8) has been patchy lately and in truth I got a bit jumpy at the thought of another repair bill.

I did notice that once the fuse was replaced there were a lot of loud clicking and whirring noises from the exhaust area for the first few starts (which having removed the fuse on the way home from the dealer 7 months ago I had never heard before !)

I'll give it a week with the fuse in so everything works as it should - then pop it back into the glove compartment for another half year and return to drinking pints of real bitter !

Hope the forum is happy with this ??!!!

Only in the Aston forum could somebody be quite so polite

[clanger]

I was told by a dealer that you need to periodically replace fuse 22 or the baffle can seize up? - is this true or a dealer myth???

[bogie]

if its a mechanical valve, or one worked on air pressure, im sure it could seize up without use....but who cares

...I guess all these owners fitting tubi and larini exhausts are not bothered, even with doing away with it for good, so I cant see its a problem...unless you really do want to make the car sound like a regular car again ......

[rickdms]

If the valve is left in one position it will seize, this can happen if the car is not used on a regular basis as well as removing the fuse, As exhaust goes from really hot to very cold add a little water, Sorry meant loads of rain water, not a good combination for anything metal, as the valve normally always seizes in the open position there is no real problem just loads more noise. And they should be checked on service and lubricated, if tight some duck oil and a little bit of swearing normally free off quite nicely.

[Murph7355]

How many valves have been reported as seizing?

[XXXAngelXXX]

none

My suspicion too.

With all respect to the guys in the US, many were suggesting removing the fuse was bad and proceeded to note how their dealers had wired the valve open. Now call me old fashioned...
