The general rule is

To secure the window glass, use only the yellow plastic adhesive tape (BMW/MINI part number 83 19 9 410 979).

The window glass will slip down if other adhesive tapes are used.

Window glass slippage will result in leaks and wind noises.

Remove adhesive residue immediately with adhesive remover (Sika remover 208, sourcing reference: BMW Parts Department). Do not press out the window glass again.

Hardened adhesive can only be removed mechanically.

Check height of windscreen/rear window with special tool 51 0 010 .

Assemble vehicle.
