Why does my 300E’s check engine light come on when I start it?

Generally, your check engine light turning on upon ignition is not a bad thing. This is just your 300E testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why is my Mercedes-Benz 300E making engine noise?

Strange under-the-hood noises can point to problems within your Mercedes-Benz 300E engine. Tapping or knocking could mean you're low on oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

What could damage my Mercedes-Benz 300E engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving the engine while still 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 300E radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your 300E when you’re out of coolant, having water in the coolant reservoir is better than nothing.

Why did my 300E engine suddenly stop?

If your 300E car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
