Car stalling while driving

[Lloyd1283]

My Q7 is stalling while I’m driving,a few days ago it wouldn’t start after stalling and I had to ring AA.

 I have changed the Cam and Cranshaft sensors, I have had the dpf cleaned and car remapped but the problem is still on going.Please help

Under what circumstances does it stall? As in cut out under acceleration or stall when stationary etc. Do you get any warning lights (glow plug light flashing etc). Are there any messages stored in a scan?
