Recommended coolant

OE BMW coolant. Don't use anything else. You need to replace it at every 4 years. Your vehicle requires a special bleeding method, unless you are familiar with it, don't attempt to do it yourself, take it to a BMW repair shop. Zee

You should add more coolant or your car might overheat. http://www.diyobd2.fr/wholesale/carprog-full-v41-1498.html
