Hello good night, my problem was in the modulus of the steering wheel where the controls of lights, of wiper and immobilizer are. To remove this piece I had to take the Opel to put the machine and unativar the piece, take off the piece, I put the new one and they coding it again with my machine I could not do it. If you remove the piece without going to the Opel, the car may not start, I think it is called the CIM module
