This exact same thing happened to me last night!! Was driving home after being out (drove fine on the way out) and everytime I came to a junction, lights or just to a stop where the revs dropped below 1k the car would lose all power.
The battery and engine management lights came on as if I had stalled, along with the ESP light (which is now constantly on).
I managed to get her re-started and nurse her home using alot of revs but every time I needed to stop she just cut out again!
When I got home, I started her up just sitting on the drive, she would fire up fine but immediately cut out when the revs dropped to idle!!!
At first I thought it may have been the battery (cold weather and all) but the lights and everything else seem to be working fine, so I can only assume maybe a coil pack, cold start valve or idle control valve being faulty
Has anyone managed to sort their problem out???
Will be sending it to my mechanic shortly.....
