Installation And Maintenance Tips
- Always disconnect the vehicle battery before working on the alternator or charging system to protect electronic control units.
- Before fitting the new unit, compare the mounting points, electrical plug and pulley layout with the original alternator removed from your BMW 3 Series.
- Inspect the 6PK auxiliary belt and automatic tensioner for cracks, glazing or noise and replace them if they show signs of wear to avoid premature failure.
- Ensure all earth straps and battery terminals are clean and tight, as poor connections can cause charging faults that may appear as alternator problems.
- After installation, check charging voltage at idle and with electrical loads switched on to confirm that the system is operating within the correct range.
- Where required, ask your workshop to follow BMW diagnostic procedures to clear any stored fault codes and verify that the charging system is recognised correctly.
- If you are not comfortable working on the vehicle yourself, have the alternator fitted by a qualified workshop familiar with BMW N20 B20 engines and their electrical systems.
