Why does my CL550’s check engine light come on when I start it?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your CL550 firing up its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Strange under-the-hood noises can point to problems within your Mercedes-Benz CL550 engine. Tapping or knocking could mean you need an oil change. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

Some driving habits are not so great for your engine.
