Notes for service technicians: Warpage
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
Very occasionally, CDs/DVDs may not be completely flat, i.e. they may be warped or buckled. With such CDs/DVDs, electronic fault correction may no longer be able to compensate for the defect when the last track is played. When played, CDs/DVDs are read from inside to outside. Because warpage is at its greatest at the outer edge, there may be reduced reproduction quality at this point.
