How does BMW drivetrain maintenance help save money?

Yes, sometimes it can. First, servicing the drivetrain system can help you avoid more significant repairs. It can also somewhat reduce tire wear.

What are the symptoms of a damaged BMW drivetrain system?

Hear noises toward the back of your BMW 840i xDrive? 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 840i xDrive differential service?

Differential service frequency varies from car to car. Double check your owner’s manual and talk with a technician. We generally 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.

Why is the malfunction indicator light (MIL) on in my 840i xDrive?

A multitude of problems can activate your 840i xDrive’s malfunction indicator light (better known as the check engine light), including issues with the engine, transmission, sensors, electrical system, or connectors.

Can my 840i xDrive malfunction warning light be reset at home?

Resetting a malfunction warning light at home may be possible sometimes, but it is never recommended. The check engine light is commonly triggered by a misfire, fault or malfunction in one of the vehicle's systems. It is important to identify and fix the underlying problem to ensure the safety and reliability of the vehicle. Resetting the check engine light without addressing the underlying issue may temporarily remove the warning, but it will not fix the root cause of the problem.

How serious is a drivetrain malfunction in my 840i xDrive?

A drivetrain malfunction in your 840i xDrive 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 840i xDrive drivetrain include the transmission?

Yes, the transmission is an essential part of your 840i xDrive’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your 840i xDrive forward. Other components in the driver train include the axles, differential, and driveshaft.
