Why does my E350’s check engine light come on when I start it?

Generally, your check engine light turning on upon ignition is not a bad thing. This is just your E350 testing its circuits. The light should turn off in a bit, but come see us if it doesn't.

Are Mercedes-Benz E350 engine noises bad?

Strange engine sounds can be a sign something’s off in your Mercedes-Benz E350. Knocking or tapping could be a symptom of low oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

What could damage my Mercedes-Benz E350 engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, revving the engine while still in Park, or slamming the gas pedal while the engine is still cold. 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 E350 radiator?

While it’s not recommended, you can use water in your E350 radiator in emergencies. Normally, you should only use a 50/50 mix of coolant and water or a pre-mixed coolant. However, if you are completely out of coolant and must continue driving, it’s better to have water in your coolant reservoir than nothing.

What can cause a E350 engine to suddenly stop?

Your E350 car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
