Cooper S (R56) L4-1.6L Turbo (N14) (2009)

X3
In the case of hot cementing (with accelerator), the missing residual bead is applied from a second adhesive cartridge (not contained in the repair kit) but
while cold and without accelerator (bubbling).
Minimum hardening period is thus not increased.
IMPORTANT:
If a second cartridge is required for cementing:
-
First apply cold adhesive to cowl panel at bottom (skin formation time)
-
Accelerator from repair kit must not be used with the second cartridge (bubbling)
Bubbling results in leakage and insufficient bonding strength (torsional rigidity, passenger airbag).
Effect of differing adhesive quantities:
Spacer buffers:
Before sticking on new spacer buffers, remove all remaining traces of old spacer buffers completely.
Position of spacer buffers must be observed exactly.
Incorrectly fitted spacer buffers will result in:
-
Windscreen glass breakage
-
Leakage (if the spacer buffer is in the adhesive area)
-
Wind noises
Assembly:
To prevent a pressure increase in the vehicle interior when the doors are closed:
-
Open a window
IMPORTANT:
-
After the adhesive bead has been applied, the window glass must be fitted within 5 to 10 minutes (depending on air humidity, temperature
and use of accelerator).
-
After 5 to 10 minutes the adhesive bead forms a skin which can no longer guarantee a perfect bond.
-
To secure the windscreen, use only the yellow plastic adhesive tape (sourcing reference: BMW Parts Service, part number 83 19 9 410
979).
-
The glass will slip down if other adhesive tapes are used.
-
Windscreen slippage will result in leaks and wind noises.
Remove adhesive residue immediately with adhesive remover (Sika remover 208, sourcing reference: BMW Parts Service). Do not press out the window
glass again.
Hardened adhesive can only be removed by machine.
Check height of windscreen/rear window with special tool 51 0 010 or 51 3 210.
Assemble car.
Hardening:
The adhesive hardens as it reacts with air humidity (with accelerator also due to mixed-in reaction paste) at room temperature.
Minimum hardening time (table) is obtained from 22 degrees C and 38 % relative air humidity.
At ambient temperatures above 23 degrees C and 50 % relative air humidity (hot countries), the adhesive open time is shortened to approx. 5 minutes
(skin formation time).
