Hi Guys, I am on the verge off shooting myself, as my car is just pi**ing me off. A month ago my Immobilizer light started flashing and the car would start and cut out straight away. Tried 2s ets of keys and the same problem. Both key just cant stop working at the same time so I called the AA and the guy spent at least 1 hour trying to find out what was causing the issue. He ran a signal test on his laptop with the key in the ignition and it was not reporting any signal being read on the key. He said that the common fault on A3's is the reader coil on the ignition. So I went along to Audi and got a new ignition barrel made from my existing keys, so I would not have to reprogramme them. Today I fitted the new barrel and recharged the battery as it went flat and guess what it still flashing. I freeze my nuts off on the bus to get to work and need my A3 back up and running. Can anyone help?
