Tobes49 Posted June 18, 2007 Report Share Posted June 18, 2007 B1 + 2 are normally for Proper V engines, EG one side on the V is B1 and the other B2. S1 + 2 are pre and post cat, With S1 being pre cat and S2 post cat. Faults will be listed B1S1 or something like that. Link to comment Share on other sites More sharing options...
