Hi , I wonder if anyone can help , I brought an 08 Astra twin top 6 months ago , and the horn stopped working more or less the min I brought it , then I had an issue with it not starting sometimes , and the controls on the steering gone a bit weird , so I did I little research and found that it is prob a cim problem as. Astra had been recalled for it years ago , anyway my question is if I got a cim from eBay , and a mechanic to fit it , does it have to be programmed to car and keys ? And would a normal mechanic be able to do this ? I did purchase a clip from Vauxhall that can be put in steering and may fox the issue but I have no faith in a piece of plastic if I’m honest and fear I need a whole cim - any advice would be most welcome
