I own a Fiat Grande Punto. Recently I was told by the authorized auto workshop that the BCM in my car has failed and needs to be fixed.
So I have two questions regarding this:
- What is the BCM and what does it do?
- They asked me to give them certain code numbers which came with my car manual and are unique to my car to them. They said they needed it to reprogram the BCM. What is the significance of those code numbers?
