The 3 volt lithium batteries are non rechargeable and will last indefinitely as long as the board isn't left disconnected from a car battery for too many years.
"vor einbau im instrum. -kombi stecker so umstecken" : this sounds like the orange arrow label stuck on the main chip? You have three pins on the board near the batteries and a two pin jumper plug to ridge two of them?
These pins and jumper were only fitted to replacement boards supplied by BMW. Lithium powered boards supplied as OE had a wire link between two holes in the circuit board near the base of the pins, but the replacements were supplied with the jumper as a switch to stop the batteries draining before the board was put into service.
