Hello since I have my V40 now (see click here ) I would like to upgrade the board computer as long as this is not too expensive. In the SuFu I found unfortunately almost only threads for the retrofitting of the board computer in phase 1. Since I have a phase 2 however, I would like to know to what extent this retrofitting is difficult/priced? That should be a lot easier than in the Ph1, because the amature board does not have to be replaced. My questions: 1. Since the cable for the BC switch should already be in place, I wonder if it really is enough to buy and connect the BC switch…. Are the sensors already pre-installed in every V40 (Ph.2)? 2. If only the BC switch really needs to be retrofitted, is it enough if I let the board computer unlock? 3. Is the BC switch for phase 1 compatible with that of phase 2 (I don’t think personally) 4. What would it cost on average? 5. Is the BC switch for phase 1 compatible with that of phase 2 (I don’t think personally) 4. there are a few good sources where you can get the BC switch? At the bay you will unfortunately only find the switch for phase 1. Thanks already in advance for the answers
