Engine briefly cutting out
Discussion
Last year I started a thread about my V8 Vantage cutting out. My first V8 Vantage suffered this on maybe 15 occasions. It got so bad that I was given a replacement car for peanuts by the dealer. The replacement has done 5600 miles in the last year and it has also suffered this problem - including twice in one day last week. The problem seems to occur when accelerating; the engine appears to die for a second before carrying on. The second time it did it last week gave a pretty violent reaction - it felt almost as if I'd changed from 1st to 6th and stalled the engine. This was not the case as i was accelerating from 20mph in 2nd but it was the same sensation as having stalled it.
I'm getting pretty pi55ed off at Aston's inability to tell me what the problem is let alone rectify it. Does anybody else have this problem? Has anybody sussed out the cause of it?
Many thanks.

My old 4.3 had this problem and they couldn't ever diagnose the problem.I'm getting pretty pi55ed off at Aston's inability to tell me what the problem is let alone rectify it. Does anybody else have this problem? Has anybody sussed out the cause of it?
Many thanks.
Happily my new 4.7 now has the same
issue.It's actually dangerous.
It's booked in to have it looked at and I will report back
Electrical gremlins?
Water ingres in the fuse box?
I got this issue last week and a warning light on my dash "engine service urgent". Aston Works have already repaired/replaced the fuse box water issue and have now said it's down to a faulty wiper motor. My wipers were staying on for too long even after ignition switch off. Apparently water had got into the motor.
I've got to say I'm really impressed with the way Aston Works deals with faults. So if your in any doubt and can rectify an issue I would certainly give them a chance. They don't have the creature comforts of loan cars etc but rest assured the guys know what they are doing.

WHOAMI - thanks for that. I am glad I'm not the only person experiencing this problem. I had it on my 06 Vantage many times and it repeated itself on the 'loaner' they gave me (twice on the same day within 100m on the same road!). The new one has exhibited the problem in EXACTLY the same place on two roads on two separate occasions. I've asked Aston if anybody else is reporting this problem.....
To be fair, the Edinburgh dealer is very cooperative and are sending up a tech to look at diagnostic codes. They've done this before but have not unearthed anything.
So far, I've experienced this phenomena on over 20 occasions..... Beat that!!!

Is it repeatable on that stretch of road? Does it do it regularly?
I've never heard of this before and my car certainly doesn't do it (20k miles in 20mths). But if you can repeat it, get a dealer to come out on a drive with you.
Do you always fill up with fuel from the same place? Is the car always similarly full when it does it? Are you coming off or on the throttle? Does it always do it in the same gear? At the same speed?
It seems really, really odd that you've (both) had it in 2 cars. Check out the warranty thread and no one has mentioned it there, so there must be something specific happening...

The problem is, Murph, that it does it very, very intermittently. Aston sent a guy up (to Aberdeen) to have a look at it; he came on a test drive but the car did not miss a beat. I use various garages for petrol so that is not the root of the problem. It occurs maybe only once every 1000 miles (then twice in he same day) so very, very hard to replicate it. It's even done it on the M6 at an indicated 80mph with the cruise control on; feet were nowhere near the pedals at the time.
The AMOC site was interesting - it does seem quite a number of folk have this problem. Maybe I need to think about a 'class action' to get them to pull their fingers out and get it sorted....

My car has just been returned from the dealers.
No fault found, nothing on the ECU memory, technician couldn't replicate fault.
Now I have a degree of sympathy here as it is an intermittent fault.
However, basic problem determination seems to be a thing of the past.
If an error code has not been recorded and shows up using their diagnostic software, they seem to assume that there is no problem.
Anyway, they flashed the ECU so we shall see.
murph a lot of techs just look at the code side of things if nothing is stored then they don't tend to go much further, usually a reset or reflash and return to customer rather than use live data which can be a lot more informative, fault finding intermittent problems can be troublesome and time consuming but can be made a lot easier. there is a device i use which i plug into the car which then the customer uses as normal. what this does is store data as you drive it which is date and time stamped, which can be reviewed at a later date, unfortunately i have not seen any dealer to date do this, when the car exhibits the fault i ask the customer to make a note of the date and time, with this information i can review the data from the device before the event and during which can really help with the diagnosis then the items that raise concern can be fully interrogated with the Aston martin diagnostic equipment, Most intermittent faults we find are down to connector or wiring issues, and most of these are usually quite easy to rectify once identified,
In certain situations especially when our customer is a two or three hours drive away we have posted our diagnostic tool with installation information takes about 30 seconds to fit, after the fault has been replicated the car is booked in for a full diagnostic,
I am not saying it is easy because interpreting the data is a skill in itself,
the technology is available just not used by all. Also depending on the fault it still may not show what the fault is, but if you can prove what is ok it will still narrow down the list of items to test.

Have you checked the immobilizer. It sounds naive, but on a previous car I had the engine cutting out when somebody else was interfering on the same frequency than the immobilizer. If it happens on the same stretch of road it could just be that there is some installation which uses the same frequency and then overrides the engine management system as you pass. In my case it was the remote controlled bridge on a ferry which when in use interfered with my engine which then cut out or would not start in the ferry queue.
whoami, Can I suggest that you, and anyone else for that matter, contact AM directly about this issue. It appears that the problem with this intermittent problem is that it is not being reported. Mine was in at the Works in November and, prior to it being booked in, I contacted AM in Gaydon to see if they had any other reports about this problem so that I could pass on this info, and solution, to my contact at the Works. Their answer was that they had no information about this being a problem for other owners although, by the time I arrived at the Works, they had contacted them to advise them of my concerns. No fault was found but it's obvious that this problem exists with many, if not all, Vantages.

Breakthrough - Aston called me yesterday to tell me they've found out what the problem is. They are picking up my car next week to put it right!!
Spooky, just as you've found a solution, mine cut out for the first time since they flashed the ECU .Would you be good enough to let me know what the solution is please?
Thanks
