Despair: The usual Fuse 22 not working on '11 V8V (Rick?)
Discussion
As per forum membership requirements, I've immediately pulled the usual Fuse 22 in the rear fusebox (as I've done on my prior Vantages), and there's absolutely no difference much to my shock! It's the yellow 20 amp at the end of the row next to the relay, marked number 22, as per usual, so I'm certain it's the right fuse.
I did some quick test drives now.. same behaviour... fuse in or out, the proper noise only comes on above exactly 4000rpm... have Aston worked it out and sabotaged this excellent feature for 2011..?

As far as I am aware it is still the same fuse at least up to 10.5 model year the only car that is different is the rapide currently, removing the fuse does not have an immediate effect as there will be a residual vacuum still within the system, I wonder if you have not left it long enough for the system to clear, try a longer run 3 or 4 activations of the system should be more than adequate to purge the system,
Hi Rick,
Thanks.. I got the car yesterday and have had it pulled since then, except this morning when I did some testing with it in and out again. Shall I leave it out for a day or so and see if this works?
I wonder if they haven't changed things in an attempt to sell the new upgrade sports exhaust (as found on the N420)..? Talked to my dealer and they said there are some new cats and other things on the new cars for new emissions regs, and this is why the starter motor and startup sound in general also sounds different and the car seems quieter on the whole...
Edit to add: Oh I see what you mean, 3 or 4 activations of the exhaust flap system should purge any residual vacuum in the pipes... okay, I'll go out and do a bunch of hard accelerations from low down to over 4000rpm and report back!

My my 10 V8 was much quieter than previous MY cars even with the pipes de corked. Just fitted Quicksilver Supersport Exhaust. It now sounds like an Aston again from start up through the rev range. In addition I think it saves a few kgs looking at the stock item after it was taken off.

The V12V handbook says the following:
Boot Fuses
Fuse. Rating. Function.
F15. 5A. Not Available
F22. 20A. Exhaust bypass valve and vacuum pump
Has anybody removed fuse 22 from a V12V and did it work?
The handbook does indeed say F22 Exhaust bypass. However the circuit information now says that F22 is not used (listed as spare) and fuse 15 does the exhaust valve bypass. The Sport button also has a similar effect, by altering the engine mapping and consequently affecting exhaust valve operation.Boot Fuses

Thanks James. So I should just try remove Fuse 15 as if it were the old Fuse 22... there's no particular risk in doing so? Any thoughts as to why the amperage rating would've changed so much, doesn't quite seem to make sense?Kind Regards,

No Clue as to why they've dropped the fuse rating considerably.
It should, however, work in the same way as removing fuse 22. Is it too early in the morning for someone to try it??
I have a 2011MY V8V in bits on Tuesday, so I can pull fuse 15 on that one as a test. It's at a dealers, so if I put warning lights on, they will have AMDS to enable them to sort it
