Can BMW drivetrain maintenance help me save money?

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

What are the symptoms of a damaged BMW drivetrain system?

Noises toward the back of your BMW 740i, leaking fluid, trouble turning — these could all be signs of drivetrain damage you want to address. Take action before something more severe happens.

When should I come in for BMW 740i 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 740i?

The malfunction indicator light — also known as the check engine light — on your 740i can illuminate for a variety of reasons, including engine issues, electrical problems, damaged sensors, transmission problems, misfires, and faulty connections.

Can you clear the 740i 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 740i'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 740i.

How worried should I be about a drivetrain malfunction in my 740i?

If you experience a drivetrain malfunction in your 740i, it is important to have it inspected by a professional mechanic as soon as possible to identify the underlying cause and perform the necessary repairs. Driving with a malfunctioning drivetrain can be dangerous and cause further damage to your car.

Is the transmission considered part of the drivetrain in my 740i?

Yes, the transmission is an essential part of your 740i’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your 740i forward. Other components in the driver train include the axles, differential, and driveshaft.
