When your car’s engine is running, oil is being pumped into the cylinder walls to keep them from closing. This process is called “choking.” When the engine is not running, carbon monoxide can build up in the cylinders, which can cause a car’s check engine light to come on and off unpredictably. If you have an M3 or a convertible, you may want to keep the hood closed when you don’t need it, just in case there’s an exhaust leak. If your check engine light comes on and off randomly or comes on for no apparent reason, this could be a sign of a serious issue. Your check engine light might be staying on just because your vehicle’s computer thinks it needs to see if your exhaust system is working properly. Or it could be something more sinister—possibly a code trying to let you know that something isn’t right with your car
