Why does my 640i’s check engine light come on when I start it?

It's okay if your check engine light comes on when you first start your vehicle. This is just your 640i testing its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Are BMW 640i engine noises bad?

Strange engine sounds can be a sign something’s off in your BMW 640i. Tapping or knocking could mean you need an oil change. Whistling could mean a belt is misaligned or there's an intake leak. Squealing may be caused by a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my BMW 640i engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving your engine while the vehicle is 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 BMW 640i radiator?

It’s not recommended you put water in your 640i 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 can cause the engine in my 640i to suddenly stop?

Your 640i car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
