Why does the check engine light come on when I start my SLK230?

It's okay if your check engine light comes on when you first start your vehicle. It’s just your SLK230 firing up its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why does my Mercedes-Benz engine sound different?

Strange engine sounds can be a sign something’s off in your Mercedes-Benz SLK230. Tapping or knocking could mean you're low on oil. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Mercedes-Benz SLK230 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. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I use water in my Mercedes-Benz SLK230 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 SLK230 when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What can cause the engine in my SLK230 to suddenly stop?

Your SLK230 car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
