The glass will slip down if other adhesive tapes are used. Window glass slippage causes leaks and wind
noises at the upper seal.
Pretension against wind noises is created with special tool 51 3 130 (three HR foam blocks).
It is absolutely essential to remove contamination by residual glue before the glue hardens using adhesive cleaner
(Sika remover 208, sourcing reference: BMW Parts Service). Do not press out the window glass again.
Hardened glue can only be removed by machine.
To prevent a build-up of pressure in the vehicle interior when closing a door:
- Open a door window.
Hardening:
The glue hardens through reaction with air moisture at room temperature.
The minimum hardening period is achieved at 22
°
C and 38% relative air humidity:
- refer to table.
The car must not be subjected to load on one side during the minimum hardening period,
for example:
- one wheel on the kerb
- lifting platform
- etc.
Moving around inside the workshop on a flat surface is permitted but do not under any circumstances drive over
approach ramps for example in multi-storey car parks.
If the minimum hardening times are not adhered to:
- the window glass will be displaced, causing leakage and wind noises.
Minimum hardening times:
- refer to table (without passenger airbag).
Glues and their minimum hardening times:
