While major issues are unlikely at low mileage, problems do arise with BMWs, especially if your car or SUV has an odometer that's rolled into six digits. The following are a few problems notable for BMWs built in the late 1990s and early 2000s, such as the E36, E38, E39 and E46. Should you run into any of the following troubles, don't hesitate to make an appointment for professional BMW diagnostics and repair to ensure no other issues develop, and so you can continue experiencing the ultimate driving machine as intended. Rough Idle BMWs from the turn of the century have become known for suffering from a rough idle, generally caused by one of two issues. The most common issue related to this is a fairly simple one, a dirty idle control valve. More often than not, the part will simply need to be cleaned, not necessarily replaced. The second issue that can cause a rough idle for a BMW is heavy rain that floods the DME compartment. Burning Oil Smell The Double Overhead Cam engines used in BMWs from the late 90s and early 00s are notorious for leaking oil from the cam cover gasket down the cylinder head, allowing oil to be burnt off. Oil leaks that drip into the spark plug wells are also fairly common. These issues are important to take care of immediately, as an oil leak can cause major engine damage if the lubrication for the moving parts is insufficient. BMW Water Pump Failure Many turn of the century BMWs used a water pump with a plastic impeller to move coolant throughout the engine. This particular part tends to fail prematurely. If the water pump's impeller fails, your car's engine will overheat, as coolant is no longer moving through the motor to cool its hot parts. BMW Radiator Leaks Plastic parts on the stock radiator of this era of BMW are known to crack over to the vicious hot and cold cycle they undergo. The most common locations of BMW radiator leaks include the top radiator pipe and the plastic thermostat housing. A cracked radiator results in leaking coolant, which will lead to overheating. Whether you drive an older BMW, or are thinking of purchasing a new-to-you one, understanding potential issues will allow you to have them serviced before they develop into catastrophic issues.
