Can Mercedes-Benz 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.

What are signs my Mercedes-Benz drivetrain is damaged?

Hear noises toward the back of your Mercedes-Benz 420SEL? 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 will I need Mercedes-Benz 420SEL 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 420SEL?

Engine problems, transmission problems, faulty sensors, electrical issues, misfire issues, and connector problems could all cause your 420SEL’s malfunction warning light, or better known as the check engine light, to illuminate.

Can you reset your 420SEL’s malfunction warning light at home?

While it’s sometimes possible to clear a malfunction warning light at home, it’s never recommended. If your 420SEL’s check engine light comes on, it’s usually because there is a problem in one of the vehicle’s systems. You should find and address the underlying issue to help keep your vehicle in great shape. By simply resetting the check engine light, you may temporarily get rid of the light, but the underlying problem is still there. It will only be a matter of time before the light comes back.

How serious is a drivetrain malfunction in my 420SEL?

If your 420SEL has a drivetrain malfunction, don't wait. Get it checked out by a professional mechanic. Identifying the underlying cause and performing the appropriate repairs right away can help prevent further damage and avoid unsafe driving conditions.

Does my 420SEL transmission belong to the drivetrain system?

Yes, the transmission is an essential part of your 420SEL’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your 420SEL forward. Other components in the driver train include the axles, differential, and driveshaft.

What Does the Drivetrain Do In Your 1990 Mercedes-Benz 420SEL

Your 420SEL drivetrain transfers power from your engine to the 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: driveshafts, axles, joints, differentials, and wheels. Care for your 1990 Mercedes-Benz 420SEL to maintain its performance power. You can help prevent repairs by checking and changing differential fluids, and lubricating bearings and gears according to Mercedes-Benz's recommendations.
