Please note, that app and ELM327 adapters designed for OBD-II compliant cars. If the car have socket that does not fit the standard, it's the big chance that protocol does not compatible with OBD-II specification too.
You might need to search some specialized app and adapter, that declare support of custom protocol for te specified car model/year. Great chance that it might be 2 different solutions for Mercedes and BMW.

Thanks!

Pretty sure the round "diagnostic" port is an OBD-1 port.
