Diagnostic Trouble Code Cross-Reference & Tables: Notes

BMW Diagnostic Trouble Codes (DTCs) are separated by model, test group reference, engine type and sometimes date of manufacture. See DIAGNOSTIC TROUBLE CODE TABLE CROSS-REFERENCE  table to determine which specific table applies to a particular fuel system type, engine, and model year. Model specific tables contain OBD-II (PCode) and BMW-specific (BMW-FC) DTCs. DTCs in model-specific tables link to appropriate diagnosis, if available. For additional diagnosis, see TEST GROUP IDENTIFICATION .

NOTE: Diagnosis is not available for all DTCs.
