I hope you can help me with something. I have a V70 II BJ 05. 2 weeks ago he had to hack because he didn’t jump on it. It only came a crack of starter and that was it. Electronics went on everything. He then called me and said if I had the 2nd key, since the coding of the key had gone off even though the door of the car opened by FB. Here is my first question. 1. How can this be that the coding of the key But the door opens by FB? He then charged me almost 200 € for reading out the error codes and again canpp 600 € for inspection. 820 € shortly before Christmas hurts. Well, the main thing the car goes again. It did so also and this morning! Car does not start again. Volvo Assis. called and they sent someone by. They thought it was the battery, which also mentioned already between the “that makes 820€” and the “happy party”. I told the nice man of towing service that he doesn’t have to tow me, since I would probably manage to replace the battery. Said, done! New battery with more power (ha, ha, ha) installed and see there, the car is buzzing again. Now to my second question. 2. Why do I have to laugh over 200€ for a fault diagnosis and supposed correction of the funny codes if I have finally fixed the “error” myself? Couldn’t/shouldn’t I transfer my money back there? ————————– — Some other questions: 3. With me, the button for locking and unlocking the rear doors (child safety) does not light up. Is that normal? 4. Does the light switch always have to be turned to the 0 position, if I pull the key or can it remain quiet, because the current runs out anyway when I pull the key? 4a. Is there possibly a signal tone if the switch is not at 0, at least nothing comes to me. My Navi has not functioned for a long time. wants 700 € for the Repa ratur. I have already replaced the laser but error “Disc can be read net!!!” remains. I was then told of that it is the control. 5. Can I change myself or do I still have to add sofware on it? 5a. Does someone know one who can do this cheaply in the area Frankfurt am Main? So, that’s it for now. I’m already looking forward to the answers.
