BMW 3-Series Alternators & Parts

The BMW 3-Series has won numerous awards during its history and is considered to be one of the most successful models by this automaker. Indeed, this car is incredible in terms of performance, but as any vehicle, it has its peculiarities. The model includes a big amount of electrical components and electronics that are intended for making your life easier, but they require qualified technical maintenance regularly. An alternator is not a complicated device; typically, it serves reliably for a long time, and the only components to fail there are bearings or a rectifier set. If telltale lamps of your car inform that there is a problem with charging a battery, don't delay checking the alternator, as the battery may not last even a few days in such a case. Finally, you will be unable to start the engine.

Apart from this, there is a production fault with alternator mounting bolt in some older models. If the pivot bolt is thicker than 4 mm, it may contact the alternator belt and cause quick worn of the latter. To fix this issue, just replace the bolt with a smaller one. If you have faced more serious problems with the alternator, consider replacing it with one of excellent BMW 3-Series replacement alternators that meet or exceed OE specifications. They are designed to provide sufficient power and durability. We also carry replacement components such as rectifier sets, brush sets, bearings, pulleys, etc.
