Help! Engine stall on my '18 AM Rapide S
Discussion
I have 2018 AM Rapide S Shadow Edition with 7k km on it for the last 3 years. The car has been a very nice run one with just few minors,
Then I last weekend, I took it to go on errands and the car was perfect for all day.
And, on the way back to home, while I was stuck in heavy traffic, engine stoped. Info screen said "engine stall" with usual engine warning lights and oil light. I restarted and it was working fine.
However for the next 30 min, I went through exact same engine stalls for about 7~8 times while the car was on idling. During this time, I did't feel any strange engine oil temp change, misfires, vibration or any RPM change.
Every function was working fine except while idling, engine shut.
Engine stalled again when I was going down to my garage at very slow speed.
I sent it to the dealer and tech guy couldn't find any faulty code!???
So could anyone give me some advice? Thanks in advance.

Not sure I can help, but I can ask some questions.
Do you get the "Engine Stall" indication every single time it stalls? Because if you do, to me that means the car doesn't think you switched it off, so your key dock is working.
Did you send it to an Aston Martin dealer (who will have AMDS)? Because I also find it difficult to believe that the car stalled, acknowledged that it had stalled, but didn't log a DTC to indicate why it stalled. Especially as it stalled on the move as well, not just at idle.

Whenever engine shut off, "engine stall" was displayed on the display.Do you get the "Engine Stall" indication every single time it stalls? Because if you do, to me that means the car doesn't think you switched it off, so your key dock is working.

I sent it to a Aston Martin official service center and there was no error code about it nor they could duplicate it.
I also talked to a local tech guy who does many supercars including AMs and he asked me to try to drive with manual at 3k~4k rpm. If that doesn't work, he suggested me clean up the throttle body. I conveyed his words to AM service center as well.
Let's see what AM HQ will say about this.
Today they sent a service email to AM service assistance center in UK

Hi had this on my 2017 Rapide S when it was a few months old from memory it turned out to be a wiring fault
Could you be more specific about which wiring fault you had?I've had mine for 3 years and never had any problem like this. I'm glad I just extended the dealer warranty last month.
