Hi, I have an A5 2010 3.0tdi and I'm having problem to start the car.
Is always starting when engine is cold, just after I use the car more than 30min and do a quick stop , dosent want to start straight away(need to leave it for 6-8min after starts with no issues).
No errors in dashboard or any noises when fail to start.

My mechanic check it but fail to find something wrong . Any ideea?

PLEASE show us the car and not you!!!! COULD be a battery problem cos when these cars lose just a small charge then they start to play up.

Have you tried with the other key? Almost seems like an immobiliser issue as in your video I didn't hear it even attempt to turn over.

It shouldn't be battery/voltage related, as when the battery is too weak to start it still tries and you get all kinds of wacky clicking noises.
