Mercedes-Benz 400SEL Problems
Closing Assist/Door Lock Issues Due to Pneumatic System Problems
Problems with the pneumatic system can cause closing assist and door lock issues.
Transmission Oil Seals May Leak on High Mileage Vehicles
High mileage vehicles may develop a transmission fluid leak from one or more of the oil seals.
Poor idle quality due to oil feed tubes falling into crankcase
Oil feed tubes break and fall into the crankcase (engine) and the tappet becomes noisy
(ticking), resulting in degraded idle quality. Our technicians recommend
replacing all of the tubes at the same time, broken or not.
Squeaking/Worn Brake Pads May Require Rotor Replacement Also
Due to the size and materials of the brakes on these vehicles, the brakes start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
ABS Modulator Failure Due to Dirty Brake Fluid
As brake fluid becomes dirty over time, it can cause a failure of the anti-lock brake system (ABS) modulator assembly. Our technicians recommend a complete brake system flush every two years to help prevent this issue.
