Can BMW service save me 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?

Noises toward the back of your BMW 745Li, leaking fluid, trouble turning — these could all be signs of drivetrain damage you want to address. Take action 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?

The malfunction indicator light — also known as the check engine light — on your 745Li can illuminate for a variety of reasons, including engine issues, electrical problems, damaged sensors, transmission problems, misfires, and faulty connections.

Can you reset your 745Li’s malfunction warning light 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 745Li?

Does my 745Li drivetrain include the transmission?

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