Why does my 750iL’s check engine light come on when I start it?

Why is my BMW 750iL making engine noise?

Strange engine sounds can be a sign something’s off in your BMW 750iL. Knocking or tapping could be a symptom of low oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing may be caused by a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my BMW 750iL engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, flooring the gas pedal while the car is in Park, or accelerating too quickly, too soon. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Is it okay to put water in my BMW 750iL radiator?

Only in emergencies. A 50/50 mix of coolant and water (or a pre-mixed) coolant is recommended. However, if you must keep driving when you're out of coolant, it's better to drive with water in your coolant reservoir than nothing.

Why did my 750iL engine suddenly stop?
