8 — plugs
To check a starter at full tension of the battery, it is necessary to connect plugs "30" (the big plug) and “50” (the small plug near big) a cable to cross-section section at least 4.0 mm2. If now the starter works faultlessly, it is necessary to check wires to a starter. If the starter does not turn, it should be removed and checked.
Exact check is carried out at the verifying stand or an electrotechnical workshop.
Removal and starter installation

10 Establish into place a starter and fix it the moment of 50 N • m.
11 Join electric wires and fix them on the plug 30 the moment of 12 N • m, and on the plug 50 the moment of 6 N • m.
Lay wires just as before removal. Watch that. That they did not rub about adjacent designs.
12 Models 316i, 318i, 320i, 323i, 328i: Connect fuel hoses and fix and in the holder. Fastening execute by means of new collars. Sealing rings apply also new, address to the Section Removal and installation of injectors.
13 Models 320d: Insert a noise isolation under a starter and fix it.
14 Establish the bottom cover of an impellent compartment, address to the Section Removal and installation of the bottom cover of an impellent compartment.
15 Attach a negative cable (-) the storage battery at the switched-off ignition. Establish hours.
