So, first drive for the year for the 2015 V12S

Take the cover off, remove the trickle charger, unlock the car. All good.

Get in, key in and press.

No whine and firing, just a gearbox fault, then a tyre pressure fault then a traction control fault,

The one thing it is not doing is starting. Any hints before I find the Aston recovery number?

The first suspect is always the battery. Having had it on a conditioner guarantees nothing.

If you have a spare battery, try that first.

People do say a weak battery in these Aston causes weird things to happen. This is one of the reasons why I changed mine when the battery was 6 years old but still working ok.

A bunch of faults showing definitely sounds like the battery to me.

I'd tend to agree with this. The chances of simultaneous failures in multiple separate systems just from being stood seems pretty unlikely - the common factor is the voltage the battery supplies to the various circuits and ECUs.

Almost certainly a kaput battery, especially if its the original one from new.

My V12VS is a 2017 and the original battery died more or less on its 4th birthday. The replacement is now 2yrs old and seems 100% totally fine, even though if anything I've been driving a fair bit less in the last 2yrs than I did in the first 4yrs....

So there's likely a degree of variability in the lifespan of them.

They aren't too expensive anyway so its not such a big deal, albeit a pain.

Your battery has lasted 7 years, so a reasonable life.

It is funny now, how the first indication of failure, seems to be masses of misleading fault messages.
If the car is so clever, why cannot it display; 'Error - Battery voltage low, 7 years old, so probably duff' ?

In the old days, we heard the starter turning over so slowly, that it would not start the engine.
Did not need a fancy dashboard then, because it was obvious to anyone listening, that the battery was weak.
In fact some onlookers might walk away. They knew the next action would be, "Please give me a push start". - smile

Agreed. I have a booster pack that works on my track day mini and my Boxster. Not willing to attach it to the vantage for fear of blowing everything to hell! Hopefully a new battery will sort it smile

Thanks all for comments…

Because that would be too easy. You're supposed to have it trailered 100 miles to an AM dealer so they can use AMDS on it at £175/hr +VAT.

Of course. Silly me.

Talking of batteries.
We are supposed to all be buying battery cars. It won't be £175/hr +VAT with those.
The manufacturers are upping the stakes. At some point between the battery warranty expiring (year 8 ish) and year 15, the dashboard will light up with errors, then you have it trailored (I was going to say to a scrap yard, but these cars are green) 100 miles to be 'recycled'.
Instead of £175 / hr +VAT, it will probably be £50,000 +VAT, to repeat the whole experience again.

A far juicier earner for the motor industry.
You think I am joking. Just wait and see.

Happily using a new IC car, to discover it is still working well after 20 years, will never be allowed again.

I had the same happening to me last Friday, only that I was stuck in a public car park in the South of France.
Called the recovery people from the insurance who sent someone out with a booster so I could start the car and drive to the dealer in Cannes who replaced the battery.
All sorted now, battery was 8 years old on a V12VSR.

Mine is nose first into a fairly tight garage, could make for an interesting extraction. We shall see… maybe they will just replace the battery in situ. Which would be a good result!

My V12 Vantage did the same, perfect one day, wouldn't start the next. Battery was the issue.

I did this too. Had a couple of erroneous messages over a couple of months that disappeared as they do, and the starter laboured a couple of times after the car had been sitting for several days, so decided to get the battery swapped before it died.

My 2005 Honda ( before I sold it) at 195K miles a message appeared on the dashboard. It said “Check battery” A battery check revealed a dead cell. $80 dollars at the local discount automotive parts store for a new battery (installed) and I was on my way.

Can I ask
Are you doing it yourself or is there some company that comes out and does it for you ?

Thanks
