Hi

This car came to me with a really weird problem...
The car would randomly cut out while driving, with no pattern at all...
After starting to diagnose the car, I have noticed something that was not initially mentioned by the owner...
The car would also randomly fail to start!
No codes on the engine ECU, and no relevant codes on the other ones...
In the end was actually this fail to start, that lead me to find the problem, not just the fail to start, but also the cutting out problem...

Follow me on this video to find out what was the problem in the end...
There was a twist during the diagnostic and repair...
So if you don't want to watch the start, where I was actually "walking" in the wrong direction, jump to https://youtu.be/K_-TLfRkP6Y?t=21m50s where the diagnostic to the real problem started...

Hope you enjoy the video.
Any questions or comments, please just put them below.
Like always, thank you for watching!
