Why does the check engine light in my 550i turn on when I start my car?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your 550i firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.

Why is my BMW 550i making engine noise?

Strange under-the-hood noises can point to problems within your BMW 550i engine. Tapping or knocking could mean you're low on oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can be traced back to a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my BMW 550i engine?

Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving your engine while the vehicle is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I add water to my BMW 550i 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 550i when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What can cause the engine in my 550i to suddenly stop?

If your 550i car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
