Hello municipality. I have read now about this new reader, made by 2 Munich mechanical engineering students. It is to cost only 75Euro and be operated with a free app on the mobile phone. The 2 want to offer the car owners a relatively cost-effective device for self-diagnosis, so that people do not have to be dragged so often by the workshops over the table-ways of any repairs, which often do not have to be at all and only overfill the bags of the friendly ones. basically a good invention! But who already owns this device and does it do what? And what can you query everything (resetting service interval, reading errors, etc……)?
