I have a Foseal ODB2 scanner and BMW E34 port connector to ODB2 connection (pictures attached). What protocol settings are needed to read the codes generated by my 1994 525i?
ISO-9141 is k-line and L-line, but if the tool can talk to both, that's unknown.
Your car uses "L-line" or sometimes called ADS to communicate engine codes.
I would search for the "stomp test" instead.
