V8V 2015 won't start after being serviced
Discussion
Hi all, some advice from the wise people here please. Sorry if the story is a bit long but i think necessary to outline the issue.
Sent my 2015 v8v,manual 16000miles, into Aston Works for a 7 year service in December along with instructions to replace cabin and air filters and to check the battery (based on nothing more that it being 7 years old and I was thinking of replacing it routinely).
This was done but they also highlighted weeping O rings on AC compressor and a 1 clean drop leak from the gearbox. These were dealt with under Timeless warranty (now expired) with new O rings and I believe the gearbox may have been removed in full or partially (5 hours labour??).
I was away on holiday so the car spent about 2 weeks there in all before being delivered back.
The car is always on a battery conditioner and has never failed to start first push .Anyhow, 2nd day back I go to use it and it starts but very reluctantly, as if battery is flat. went for a 5 mile run then stopped and it refuses to start at all, no noises at all. So I connect a trickle charger under the bonnet which shows full charge next morning. Again, same symptoms, poor start but it does start. Go for 20 mile run and it will restart once or so but reluctantly.
So I bite the bullet and buy a new Bosch S5013 battery and fit it (after charging it overnight). Car starts but again rather reluctantly. I leave it charging via the under bonnet points overnight and next morning charger shows battery full it won't start at all. I rock the car in gear and it reluctantly starts for first time then refuses second time.
I put a volt meter across the under bonnet points.12.5 v engine off, 11.9 volts engine running with headlights on.
Any ideas please? Alternator? starter motor? a short? And why the coincidence with the recent service works when I've never had any problems in the past, in fact it has always impressively started as soon as the key is pushed and now is dead.
Many thanks and Best Wishes for the New Year.

Sorry to hear your having problems.
The starter motors & alternators on these engines seem to be very reliable and your car is only 7 years old.
If your problems started right after the service at Works I would definitely take it back to them, explain your problems and ask them to have another look at it on a FOC basis.
Let us know how you get on.

Just rechecked voltages (or somethings changed) 12.5v engine off, 14v engine running. I just tried a suggestion from elsewhere and put a jump lead from block to body to earth the engine. It starts quite crisply. I think Works dislocated or forgot to reconnect something, I'll get on to them after the holidays.

Sounds to me like the braid strap between body and engine has some corrosion preventing a good earth - if it was not connected then the car wouldn’t crank at all, as the engine sits on rubber mounts that act as isolators. It is possible that, if Works dropped the gearbox they may have undone the braid and not reconnected it properly. The additional connection between body and engine that fixes the issue is pretty conclusive, and this is not the first case I’ve heard of on a VH Aston. As far as I can tell from looking at the wiring harness diagrams on Scuderia Parts the earth strap for a Vantage is at the rear of the car, in the tunnel by the gearbox on the LH side. Probably just needs to get the car on a ramp, remove the rear undersheets, take off the braided strap, clean the strap eyelets, bolts, washers and the body where it attaches, reassemble, tighten and then protect with some silicone grease. Sounds like a call to Works and ask them to fix it.
My problem now appears to be solved...AMW have been very helpful and acted extremely promptly. They collected the car by transporter and inspected it in their workshops. They agreed with my (our) diagnosis of a poor earth strap, apparently it was corroded. This has been rectified and the car delivered back following day. tried it a few times and all appears good now, So many thanks to you all here for your input, it was very helpful.

Do you know if the strap was removed during the service and put back corroded?David W. said:

I don't know and didn't ask. My guess is that it was removed for the gearbox work then not correctly reinstalled .But that's only a guess. AMW are hardly likely to admit to it ,I thought, so I didn't press them. They were very helpful in any event.

Glad it's getting better. It will be good to know the outcome after the chat with Works.
I am thinking of going there myself this year.
where you mention block, was that the engine block?
Kevin
Sorry forgot to reply to you. Yes a jump lead from a big nut on the engine block itself and the other end to a big nut on the suspension turret or somewhere near that looks like an earth. Once earthed like this it started first time.I am thinking of going there myself this year.
