Hi guys.

Yesterday my A8 would not start, basically after turning the key nothing would happen. I had similar issue before but back then after a couple of minutes it would start no problem.

Today I got to the car with a charged up battery as I though maybe the voltage is too low, had some problems with alarm turning on randomly so I though the battery went flat a bit. Before hooking up the replacement battery I tried starting the car again and it started no problem. Jumped in and wanted to drive away but the engine started shaking and the revs started to go down until the engine stalled. Started it again no problem, kept the foot on high revs for a few seconds but it started shaking and dying again. After a couple of tries, now after starting it just shakes and would stall in 10-15 seconds.

Hooked it up to vag com and the below is the list of engine codes. Any idea what it might be? Seems like it is one side of the V8 engine. Your help would be much appreciated.
