ASR light flashing on 147
I have an Alfa 147 and when I accelerate over 40 mph the ASR light flashes, and it will not allow you to go any quicker. I have had the car with my mechanic; he plugged it in to the computer and it was showing an oxygen sensor fault. He tried a new air mass meter in it, but it did not cure the problem. He is puzzled now as to where the problem lies. It would seem that it is a sensor problem, but the only code registering was relating to the oxygen sensor. Has anyone else had a similar problem? Any advice much appreciated.
