WARNING: This page is about a different car, the 2016 BMW Z4, 2015 BMW Z4, and 2014 BMW Z4. However, it is still accessible from the selected car via links, so may be relevant.
  1. 2.1 Disassembly in general: 

    The following dismantling methods are applied, according to the version:

    • OSCILLATING KNIFE  (not permissible for vehicles with window bonding on carbon body components)
    • Cutting wire with WIRE PULL HANDLES 
    • "SPIDER " window glass removal system (unsuitable for severely damaged window glass)
    NOTE: When cutting out the window glass with wire pull handles, there is a risk of damage to the window glass if the wire is pulled over the window edge.
    Unless otherwise described, only use this method when replacing the window glass.

    Follow the individual repair instructions!

  2. 2.2 Disassembly of damaged window glass: 

    The disassembly method described in the REP may be unsuitable depending on the degree of damage.

    • e.g. suction cups cannot be attached to window glass around cracks
    • Damaged window glass may damage and tear the nylon string

      Attention! Risk of damage! 

      Use one of the other disassembly methods at your own discretion in the event of severely damaged window glass.

      Make sure adjacent components are adequately protected.
