Many thanks to Axel for the tips. So if anyone knows about diagnostics, it’s Axel.
It only could be something universal that covers as many vehicles as possible. Then it shouldn’t be that expensive, easy to use, and should include all adapters and OBD connectors for all vehicles.
I found a used device that fits quite well. It’s a leasing return from another EU country, with updated software and a 2-year update guarantee.
The ordering process was then a bit more difficult. The company buys all technical equipment and tools from a dealer near Hamburg. The dealer buys and gets the stuff from Germany and England, and takes care of the logistics. Either it is delivered to Bremen, and stored there until enough parts are together to fill a sea container, to delivered by ship to Ghana. Or, as is this case, if it has to go faster, by air freight. The middleman takes very little money for this. It will probably arrive here this week.
There is still diagnosis on demand. But the internet connection is too unstable, and there are no suitable end devices like laptops. And I think the prices (about 50€) for ½ hour diagnosis are simply too expensive.
What I’m still missing are the service documents.
The manufacturers only give them to workshops. There are some providers who offer electrical parts catalogues, wiring diagrams and service manuals, but the prices are in the range of about 60€ per month.
So if anyone has a good idea, let me know.
