LIN bus 1 has a malfunction. There is a short circuit to ground or an open Current and stored circuit.

This was and still is in the KEYLESS-GO section of my code reader, all keyless (2) work fine and have changed both batteries for good measure.

Have any fellow MB owners come across this code and could possibly shed some light on what the fault maybe.
