BMW z4 2016

I can't get my One+ to read my BMW's OBD port properly. I flashed it with the telelogger app, but it fails when reading the OBD port. I changed its code to retry a connection when failed and used PROTO_ISO_9141_2 as protocol, which that made it connect after the first failure, but it never reads any PID information and accumulates errors until its ultimate shutdown.
