Why does my R350’s check engine light come on when I start it?

Why does my Mercedes-Benz engine sound different?

Strange under-the-hood noises can point to problems within your Mercedes-Benz R350 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 could be a sign that something is wrong with your brakes — not the engine.

What could damage my Mercedes-Benz R350 engine?

Can I add water to my Mercedes-Benz R350 radiator?

However, if you are completely out of coolant and must continue driving, it’s better to have water in your coolant reservoir than nothing.
