BMWs use an external oil cooler to regulate the temperature of engine oil and prevent a breakdown in viscosity and lubrication characteristics. If yours has suffered damage or developed a slight leak, make sure to replace it and keep the engine oil where it is supposed to be. Keeping this system properly serviced will significantly improve performance and increase engine life.
A common system of a bad heat exchanger is oil leaks from that particular area. Keep an eye out and replace asap if this happens. Genuine BMW Heat Exchanger - This item fits the following BMW Chassis: E71,F15,F16 Fits BMW Engines including: N55,N63,N63N
