Affecting: Anything with a BSM or PSF engine fusebox

Just to add another dimension to the process of fault-finding, the various engine components such as sensors, injectors, fuel pump etc. are supplied by a computerised fuse box in the engine compartment. This means that if it develops a fault - usually intermittent, it can cause various fault codes to be stored in the engine computer, ABS computer, parking brake computer etc etc. Now you don’t know which faults are true and which ones you must ignore. Experience is your only hope, so if you have random symptoms or fault codes, it may be worth replacing the engine fuse box, also known as the BSM, PSF or similar acronyms.
