Just thought I would resurrect this thread and ask if everybody is now cured by having a new fuel tank fitted.

Had my car two weeks now and its done the hesitation upon accelerating thing about 4 times and cut out twice when coming to a standstill at the lights - very frustrating and I can see in the wrong circumstances it could be quite dangerous!

Clearly I need to speak to the dealer tomorrow morning but wanted to know if the fuel tank was the definitive fix!

Hey Adam,

I have had my P+J back for a week or two after the new fuel tank was fitted. I have not seen the problem again but absence of proof is NOT proof of absence.

I really strongly recommend that you get your dealer to get the laptop and log the data - you can see what I had to do to get this sorted and it was a real song and dance.

I'd recommend that you get your dealer to get in touch with AM Aftersales Management in Gaydon - then ask about other folks who have had this issue. If you want to get in touch with me offline then I'll be happy to have a chat. Following the no-naming and shaming policy I don't want to put details up here - even though they would just be details of the right folks with whom you should talk.

John

I continue to use mine on an almost daily basis now and have had no hiccups since the new tank was fitted. That was a couple of thousand miles and she feels just fine!!

Well just got my car back. They connected it up to the diags computer and said they could see the error codes the car had recorded. (result as I half expected there to be no trace).

Anyway he said they didnt think it was the fuel tank as Gaydon had analysed the error codes and said my ECU was missing some of the programming it had learnt (Ive no idea how an ECU can loose programming but....). So they have reflashed it and asked me to try it out.

On the way home things seemed a bit smoother generally but it could be in my mind. Anyway time will tell if its fixed or not.

Hmmm, mine has done this about three times over the past few months also. Need to take it in anyway as all the electrics went dead on the way back from Le Mans (speedo etc all went to zero). Ho hum.

Mark & Adam - good luck to you both. Once you get the laptop plugged in and you replicate the fault you are cooking on gas.

Mark - sounds like you may have a faulty exhaust catalyst. That was the first problem that the mechanics found, then the new fuel tank was fitted...

I've had this as well on my Vantage. Having read the whole thread it sounds like the same issue as oceantools and one or two others have experienced. In my case it's a brief cut-out at around 2,000rpm when accelerating hard from a light throttle. Defo feels like fuel injection-type problem. Happened two or three times over the last month (though bizarrely not during a 2,000-mile roadtrip!)

Will ask AM to look at it during upcoming service. Some of the solutions on here look v useful so well done to those who posted. Obviously I'll report if I get a different diagnosis / solution.

My dealer is currently looking at the "engine cutout" issue and asked me for VIN's of other V8 Vantage owners that have the same problem to find out, if certain ranges of cars are affected.

So please anyone with the typical cutout problem (not the engine dying completely), please send me a PM me with your VIN.

Your help is greatly appreciated.

I know that my car is not the ones on this post but I have owned a DB7 zegato which has had the stop dead at speed problem. I have only had the car a few months and read a post regarding this problem. I am trying to contact gmaclean [a previous owner] to find out if the problem was identified and fixed so if you are out there or someone knows gmaclean I would be pleased to hear. So far I have not had the fault although the check engine light came on when the fuel level was half of the reserve. I am not surprised by this as lots of cars have issues with petrol caps and tank pressure.

6 months after the new fuel tank was fitted and this problem has not happened again.

So it looks like the new fuel tank resolved the problem.

In my case they did a software update for this and the hesitation in automatic mode. Its only been 2 months, but no further cut-outs and automatic mode is better, not perfect, but much better. Mine is an 09, so there may be different causes of this same phenomenon depending on the year and other factors.

Good to hear John.

My car still does it every 150 miles or so. Goes in again in a few days for servicing and they are having a look at it again.

The last time mine went in for invetigation they did a software fix. I cannot remember the precise details but it is something to do with the engine management software entering a calibration mode at an incorrect moment. It was maybe something like 'it should only enter calibration mode in 5th or 6th gear under certain circumstances but was entering this calibration mode in 2nd gear when it should not have been.' Sorry I cannot offer more precise details. However, the good news is that since they performed this mod the fault has not reappeared in around 1500 miles of driving.

Do you remember at what date they did this update ? Last time they investigated the problem back in september.

Good for you! As a fine example of the nice people on pistonheads you were kind enough to give me a great deal of assistance and pointers when I first hit this problem. Cheers and happy driving!

Just had a look at some old emails. The car was tweaked mid-November. There is a very brief description of the problem - a "coast-down re-learn procedure had lost it's memory. The code was re-flashed and was confirmed as being retained in memory".

As mentioned earlier, i've not had any recurrence of the problem. It may just be worth running that one by the dealer should you experience the problem.

Thanks very much Ocean Tools for your help, greatly appreciated.

Will talk to my dealer.

Or better switch to a V12V, that might be a final solution biggrin

Happy to report that I've just taken delivery of a March 06 V8V and, yes, I do have the stuttering + cut-out issue!!!
Experienced 2 cut outs in the 30 miles I've driven so far, both when idling at junctions or red lights. Stuttering was a bit more common, with the car generally feeling hesitant at low revs in 1st or 2nd gear, and stuttering a bit before regaining composure.

I've booked it in next Thursday, let's see what they say!

Since this topic popped back up, I might as well do an update.

Its now been 18 months since they did the software update and it has not stalled since. So in my case, the software update did fix the problem. This is on an 09 SportShift.

Hmmm

I've got a 10 Manual, and very occasionally the engine cuts out. It's always before it's up to full temperature, and after coming to a halt after a bit of slow moving (typically, after a 5 minute drive into my village if there's a few cars queueing at the crossroads).
It's very strange, as there's no misfiring or anything - it just stops. If I'm not looking at the instruments I don't even notice until I try to move off! Only happened a few times, but sounds rather different to the above problems.
I also suspect there's a flat spot around 4.5K revs, but haven't looked into that one yet!

So the car died on me on Friday night, in the not very practical location of Wardour Street...
Engine cut out and refused to turn back on.

Well the morning after I opened the bonnet and noticed the hose connecting the engine to the radiator had popped out and was no longer connected to the intake!
Of course as soon as it was reconnected the engine started 1st time without fail.

Now I'm wondering, how much of my problem (stuttering and engine cuttting out) might have been cause by the loose hose...? Answers on Thursday after Nick Mee takes a look at it.
