Hello together, *hope, I’m in the right forum* I would like to address a topic that mMn. is too short and I’m looking forward to your opinions. As a private hobby screwdriver, I find it very difficult to get to the technical documentation of the car manufacturers. Fortunately, you can solve many problems with technical expertise. But when it comes to electrics and complex repairs, modern vehicles without the manufacturer’s technical data are almost the same. This starts with the right tightening moment for a screw and goes up to the documentation of the electrotechnical/digital systems. Apart from this, decent repair guides often save a lot of time and errors. Even in the area of CAN diagnostics and programming you can’t get very far without proper documentation if you can’t afford a fully documented diagnostic system. You can forget about the manual at all. The costs for most hobby screwdrivers are simply too high. But even there are often important information missing. Just like with the good old “So is it done” books. Information platforms of the manufacturers (e.g. erWin of VW) are beyond expensive. So the big research starts in the vast expanses of the Internet, which according to experience is not always crowned by success. Nevertheless, I am very grateful to communities and forums, like this one. The manufacturers should be obliged to make all technical documentation available to their customers free of charge. It is an unding that private customers, but also free workshops, must invest in this technical information and that manufacturers still enrich themselves with it. Especially from the point of view of sustainability, this should be a matter of course. I study computer science and there almost everything lives from detailed documentation. Since I am used to excellent documentation, these business practices of the car manufacturers very upset me. How do you see the whole thing? Where do you get your information? I’m looking forward to your opinion on the topic!
