Why does the check engine light in my E450 turn on when I start my car?

It's okay if your check engine light comes on when you first start your vehicle. This is just your E450 testing its circuits. The light should turn off in a bit, but come see us if it doesn't.

Why does my Mercedes-Benz engine sound different?

Unusual noises can signal a problem with your Mercedes-Benz E450 engine. Tapping or knocking could mean you're low on oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing may be caused by a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

What could damage my Mercedes-Benz E450 engine?

Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' flooring the gas pedal while the car is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Steer clear of these habits to help protect engine performance and efficiency.

Can I use water in my Mercedes-Benz E450 radiator?

Only in emergencies. A 50/50 mix of coolant and water (or a pre-mixed) coolant is recommended. However, if you must keep driving when you're out of coolant, it's better to drive with water in your coolant reservoir than nothing.

What can cause the engine in my E450 to suddenly stop?

Your E450 car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
