Why does my G55 AMG’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 G55 AMG testing its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Why does my Mercedes-Benz engine sound different?

Strange under-the-hood noises can point to problems within your Mercedes-Benz G55 AMG 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 G55 AMG 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 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 add water to my Mercedes-Benz G55 AMG radiator?

It’s not recommended you put water in your G55 AMG radiator unless it’s an emergency. Under normal circumstances, use a 50/50 mix of water and coolant or a pre-mixed coolant. But, if you need to keep driving while out of coolant, using water is better than driving with an empty coolant reservoir.

What could cause my G55 AMG engine to suddenly stop?

If your G55 AMG car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
