31 00... Information on replacing shock absorbers: Effect
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2012 BMW 328xi, 2011 BMW 328xi, 2010 BMW 328xi, 2009 BMW 328xi, and 2008 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.
This is not necessary for technical reasons and causes the manufacturer not to recognize the unnecessarily removed shock absorbers as defective parts. Unnecessarily high costs for the customer can be avoided by replacing the shock absorber on one side only.
