Hello, since the ignition cable of my Omega unfortunately gave up the spirit during my holiday, it had to be quickly renewed at an Opel dealer. Since no original part was available, he installed a cable from the second equipment manufacturer (it had to go quickly). I arrived at home today, because I still have to make the valve cover seal, and he said that he wants to change all (!) 6 cables again, because he does not know whether the control unit can cope with the replaced cable of the second equipment manufacturer. Should it cost 350 euros. I first refused to get advice here. Can this really be that a FOH replaces a ignition cable and chooses a wrong one, which hurts the car? Somehow, I can not quite imagine that just because of the warranty. What do you think about it? Or does my FOH just want to make a little money quickly and tell me that this has to be changed?
