Can BMW drivetrain maintenance help me save money?

Servicing the drivetrain system can help you save money by saving other parts of your vehicle. A bad drivetrain can put undue stress on other vehicle parts and lead to premature wear and tear.

What are signs my BMW drivetrain is damaged?

Hear noises toward the back of your BMW 745Li? 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 745Li 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 triggers the malfunction indicator light (MIL) in a 745Li?

Engine problems, transmission problems, faulty sensors, electrical issues, misfire issues, and connector problems could all cause your 745Li’s malfunction warning light, or better known as the check engine light, to illuminate.

Is it possible to reset the 745Li malfunction warning light on my 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 745Li'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 745Li.

How serious is a drivetrain malfunction in my 745Li?

A drivetrain malfunction in your 745Li 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.

Does my 745Li drivetrain include the transmission?

Yes, the drivetrain system in your 745Li includes the transmission. Other components in the drivetrain are the driveshaft, axles, and differential. Together, these components deliver power from the engine to the wheels to push your 745Li forward.

What Does the Drivetrain Do In Your 2004 BMW 745Li

The drivetrain is responsible for transferring power from your 745Li's engine to its wheels. It spans the length of your vehicle, from the transmission to the axles.

When you maintain the drivetrain in your 2004 BMW 745Li, you help maintain your vehicle's power. Follow BMW's recommendations for lubricating bearings/gears and checking/changing differential fluids to minimize repairs over time.
