Immobilizer malfunction on 156
I have had a couple of major issues over the last two years: first, I had to have a new ECU and now the immobiliser is malfunctioning. After the problem started I took the car to the local main Alfa dealer where I was advised that I needed a new immobilizer unit. But worse than that I was also advised that the appropriate immobilizer unit is no longer manufactured. I am able to start the car by entering the code via use of the accelerator pedal (as per the handbook) but this can be an issue if the car stalls in certain motoring situations. Is there a source for out-of-production parts and what are the implications if a new unit is obtained; ie what other parts will be required to ensure that the various sections of the system co-operate?
