ALFA 147

Immobilizer 147

Hi ,I'm from the island of Chios,Greece and I own an 147 (2002).
I have a problem with the immobilizer.Sundenly the screen shown "immobilizer failure"- "code". At first i thought it was a problem with the key.the battery moved from it's position after a drop,but i put it in place.The problem stopped but just for one day.Today it just won't start.I tried to reprogramm it with the code(the technichian told me the manual way) but it didn't work.The dealer says that I have to change the unit of the immobilizer in the car.Any suggestions?

I believe there is a pick up arieal around the ignition barrel - this is sometimes at fault on the GTV. You could try that.

Re: Immobilizer 147

the most ocmmon cause is a bad connection between teh aerial and codebox. thre aerial is on the igniton switch, reomve and then reocnnect ir wiring connector. now follow the wires to the codebox, up near the fusebox, when you get to the codebox remove and then reocnnect its connector. if you cant be bothered to do all this just wiggle the wires to the left of the fusebox and it should work.
