Research on Alternator for BMW 745i

Leaving the lights on overnight would be a good reason to need a jump start, but you should not have to jump your BMW 745i multiple times a week. This is only one sign of a bad alternator, and though it's a part that can be pricy to replace you need the alternator to keep a charge in your battery. Whenever you encounter BMW 745i alternator problems, take them seriously or else you could be left stranded.

What is an Alternator?

You may not be aware that your car's battery is not a disposable one. It does have a lifespan, but it's much longer than that of a standard double A battery. This is because it's a rechargeable battery that is charged by the alternator. Your battery's energy is used to get the car started, and while you drive, your alternator recharges the battery. Newer models such as the 2002 BMW 745i have water cooled alternators. These are designed to keep the unit cooler during operation so it lasts longer.

How many years does an alternator last?

Most alternators will only last between 40,000 and 100,000 miles before needing replacement, but if you are one of the lucky ones to own a water-cooled BMW alternator, yours could last much longer. Many drivers have reported water-cooled alternators lasting well over 100,000 miles, but if you still haven't reached 40,000 and experience some of the warning signs of a failing alternator, it's a good idea to get it checked out so you won't be left stuck somewhere.

Signs of a Wearing Alternator

Your alternator usually will give you several hints that it is wearing out. One of the first is failure of the accessories. Most accessories, such as the interior lights and radio, are operated by the alternator. If your dash lights or cabin light is dimmer than usual or your radio won't work as it should, you may have an alternator issue. Since the alternator helps to keep the battery charged to its full capacity, problems with the alternator may show up as battery issues at first. Your dashboard battery light may come on, and you will likely need more frequent jump starts because your alternator is not recharging the battery as it should. These are all signs to take seriously, and your next stop should be to your BMW dealer or a mechanic to get a BMW 745i alternator replacement.

How much does it cost to put in a new alternator?

Alternators are not cheap, and water-cooled alternators tend to cost more. If you have a standard model and need a new part, you may pay your mechanic anywhere from $1077 to $1496 for a 2002 BMW 745i alternator replacement. While this does include the parts and labor, it does not include higher end parts or the cost of labor from a BMW dealer's service center, which is usually higher. To save money, consider purchasing your own alternator from an online auto parts superstore such as PartsGeek.com, where prices are low daily, and you can spend less than the full cost on almost anything for your BMW 745i. It's the smart thing to do when shopping for new parts for your car.
