Can BMW service save me money?

Yes. Servicing the drivetrain system can help you avoid more significant repairs. A bad drivetrain can put more stress on other vehicle components.

How do I know if my BMW drivetrain is damaged?

Hear noises toward the back of your BMW 745i? See fluid leaking? Having issues turning? These could all be signs of drivetrain damage you don't want to ignore. Take action quickly to catch repairs or replacements before something more severe happens.

How often should I come in for BMW 745i differential service?

Double check your owner’s manual and talk with a technician. Differential service frequency varies from car to car. At a minimum, we recommend getting your differential inspected and the differential fluid changed as a part of your regular vehicle maintenance routine since your vehicle cannot function without a differential.

What causes a 745i’s malfunction indicator light (MIL) to illuminate?

If your 745i has its malfunction warning light (more commonly called the check engine light) illuminated, it could indicate engine troubles, problems with the transmission, electrical issues, malfunctioning sensors, connector problems, or misfire issues.

Can you clear the 745i check engine light on your own?

While resetting a malfunction warning light at home is technically possible, doing so is not advisable. The check engine light is typically a sign of a problem in one of your 745i's systems, and simply resetting the light will not address the underlying issue. Instead, you should bring your vehicle to a reliable auto shop to have the underlying problem identified and fixed to help ensure the safety and reliability of your 745i.

How worried should I be about a drivetrain malfunction in my 745i?

A drivetrain malfunction in your 745i should never be taken lightly. Driving with a malfunctioning drivetrain can put you in danger and lead to further vehicle damage, so it's essential to have a qualified mechanic assess and repair the problem as soon as possible.

Is my 745i’s transmission part of the drivetrain?

Yes, the transmission is an essential part of your 745i’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your 745i forward. Other components in the driver train include the axles, differential, and driveshaft.

What Does the Drivetrain Do In Your 2004 BMW 745i

The drivetrain is responsible for transferring power from your 745i's engine to its wheels. It spans the length of your vehicle, from the transmission to the axles. It’s a very intricate system of moving parts and is comprised of everything after the engine transmission: axles, wheels, driveshafts, differentials, and joints. When you maintain the drivetrain in your 2004 BMW 745i, you help maintain your vehicle's power. You can help prevent repairs by checking and changing differential fluids, and lubricating bearings and gears according to BMW's recommendations.

When to Get BMW 745i Drivetrain Repairs

You don't want to go to just anyone for drivetrain repair. Drivetrains for front, rear, and all-wheel-drive and 4WD vehicles are all different. You want to come see the technicians at Firestone Complete Auto Care. We can take care of most 2004 BMW 745i drivetrain components including the driveshaft, CV axles, and CV joints. Your BMW 745i may need driveshaft attention if you feel vibration as your vehicle accelerates, clunks when shifting, heavy vibrations in your floorboards, or resistance when turning. There isn’t necessarily a concrete timeframe for when drivetrain repair will be needed. The system’s parts and pieces don’t have a set expiration date. Your driving style and climate can have a lot to do with how the drivetrain system ages. Your best bet is to visit Firestone Complete Auto Care when you first notice a problem with how your BMW 745i drives.

How much does it cost to fix your 2004 BMW 745i drivetrain? Minor differential repairs, like seal or gasket replacement, are usually pretty affordable. But bigger repairs, like bearing or gear replacement, require more labor and can therefore be more expensive.
