Why does my C230’s check engine light come on when I start it?

It's okay if your check engine light comes on when you first start your vehicle. This is just your C230 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 C230 making engine noise?

Strange under-the-hood noises can point to problems within your Mercedes-Benz C230 engine. Tapping or knocking could mean you need an oil change. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can indicate a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my Mercedes-Benz C230 engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, flooring the gas pedal while the car is in Park, or accelerating too quickly, too soon. Steer clear of these habits to help protect engine performance and efficiency.

Can I add water to my Mercedes-Benz C230 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 C230 when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What can cause a C230 engine to suddenly stop?

Your C230 car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
