Your Mercedes will warn you when there's something wrong with your engine. Whether you can hear a strange noise from your engine, such as a knock, or whether your oil light or engine service light is on, you need to be aware of potential problems.

One of the things you can look for when your oil light flickers is whether or not your oil pressure is low. When you check your oil, if the level on the dipstick is low, it could be that you're leaking oil or that something is wrong and you are burning oil. You can add oil to your Mercedes, but that will only relieve the low pressure condition for a time. It won't fix the problem.

If your engine is leaking oil, you'll be able to see it underneath the vehicle. It could be that you need a new head gasket, or that your seals are worn. It could be that your rings or your cylinders are worn, too. Generally, you're not going to be able to fix these problems yourself, but you're going to need to bring your Mercedes in to have it serviced.

The good news is that the engine or oil light doesn't always mean a major problem. It could just mean that one of the sensors is malfunctioning, or that the warning light is not working properly. Still, to be sure, you need to bring in your Mercedes as soon as possible to have it checked out at your Mercedes dealer near Princeton (NJ) today.
