Over the past 2 months my car cut out twice whilst driving with the coil light come. When I pulled over I tried to start the car but only ticked over for 3 seconds then keeps cutting out.

I waited for about 10 minutes to start up and then ran fine. I did a scan with the torque app on my phone but didn't bring any codes up.

At 1st I thought it might be the common injector problems but my car is a 2006 A4 2.7 tdi which wasn't effected.

Doing a Google search and watching YouTube, it could be the high pressure fuel pump ?

Anyone able to shed some light on this. I keep feeling the car might cut out again, somewhere that I might not be able to pull so easily.
