Do you maintain your x5 e53 yourself?...Your experience appreciated!
The components requiring professional 'flush' are all those that contains oils, hydraulic fluids and other fluids. My mechanic said that unless you're a qualified BMW service engineer, you run the risk of servicing your car improperly. It's your choice. It's a risk you take in servicing your own car. A mechanics background however, if you have one, would of course help, but BMW cars, like Mercedes, are designed differently and include subtle interrelationships between separate parts that would not be known to people who have not been educated about them.
