Hello an acquaintance and I am supposed to get a truck from Magdeburg on Wednesday and wanted to ask if he also needs a speedometer disc. He is not a professional driver and it will probably be his only truck ride a year. The real problem is that we do not know what kind of disks we should take with us because there are also different ones and we do not know what kind of tachograph is installed. It is a MB 1117 suitcase Bj 1998. As I assume that we can need one Maybe someone might tell me where to get some so we can buy some up there.
