Why does my CLA250’s check engine light come on when I start it?

Strange engine sounds can be a sign something’s off in your Mercedes-Benz CLA250. Tapping or knocking could mean you're low on oil. 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.

However, if you need to continue driving your CLA250 when you’re out of coolant, having water in the coolant reservoir is better than nothing.
