Why does the check engine light come on when I start my 740i?

Why does my BMW engine sound different?

What could damage my BMW 740i 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 pushing 'the pedal to the metal' before the engine has warmed up. Steer clear of these habits to help protect engine performance and efficiency.

Is it okay to put water in my BMW 740i radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your 740i when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What can cause the engine in my 740i to suddenly stop?
