Why does the check engine light in my 560SEC turn on when I start my car?

It's okay if your check engine light comes on when you first start your vehicle. It’s just your 560SEC firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.

Are Mercedes-Benz 560SEC engine noises bad?

Strange under-the-hood noises can point to problems within your Mercedes-Benz 560SEC engine. Tapping or knocking could mean you need an oil change. A high-pitched whistle could signal 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.

What could damage my Mercedes-Benz 560SEC engine?

Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving the engine while still in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Is it okay to put water in my Mercedes-Benz 560SEC radiator?

However, if you need to continue driving your 560SEC when you’re out of coolant, having water in the coolant reservoir is better than nothing.

Why did my 560SEC engine suddenly stop?

If your 560SEC car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
