If I cannot get anywhere with this and you are serious and have the ability to persuade, I would take any assistance and be grateful.
I was going to pull it apart and see whether they just haven't wired it correctly. But if it is what they say, programming, I wouldn't know where to start.
I initially bought the car new at Medindie, where I had it serviced for many years. They would not replace the faulty unit initially. Then they moved to Unley so I've had the replacement ICC fitted at Rebel Ford, Elizabeth. I just spent over 7K with them repairing all the suspension and various other issues. You'd think they would assist a good customer.
