Removing windows with a "Spider" (M3 base, M3 Competition, M3 Competition M xDrive, M3 CS)
Windshield removal system "Spider"
Accessories required for operation (not included):
Cordless screwdriver/drill with at least a 10.8 V Li-ion battery or a 18 V Ni-Cd battery and variable speed
Attention!
Handle sharp-edged tools with care (risk of damage to the head airbag and the window glass)
Attention!
Always keep both suction cups dry and clean to ensure optimum adhesion on the windshield
Suction cup may not be applied at the damaged point (crack in window glass)
The bearing bushes of the shaft (spindle) must always be lubricated
Always wear safety goggles and protective gloves for your own safety

The procedure for disassembly of the windshield is described below as an example
Deviations in the work procedure can be found in the vehicle-specific repair instructions
General
A cord approx. 6.8 m long is used to cut through the adhesive bead
The cord length to be used is identified by a short red mark (A) approx. 5 cm
The part of the cord laid outside around the window glass (approx. 5 m) is identified with a long red mark (B) (approx. 18 cm)
The marks are applied so that the cord has to be pulled from the inside to the outside
Preparation
If required, unwind cord from roller (1) up to the second red mark (approx. 5 cm long) and cut off
Make sure the cord lies below the window glass at all four corners
Check that the cord is not caught on clamps or body
Secure window glass on outside with adhesive tape against sliding
Feeding in the cord on the separation device
Normally, the adhesive bead is cut through counter-clockwise seen from the passenger compartment
- This means the cord must be fed into the separation device as shown in graphic A
When accessibility is not optimal, the opposite cutting direction may be required (comply with vehicle-specific repair instructions)
- This means the cord must be fed into the separation device as shown in graphic B
Feed cord into coil and wind it on, at the same time trapping the end of the cord
When winding the cord, the correct direction of rotation on the separation device must be observed
Cutting out procedure
Optimum cutting is guaranteed when the cord is at an acute angle to the adhesive bead. There is a risk of the cord ripping if the angle is too obtuse
The separation device must be positioned correspondingly to achieve the appropriate angle
- Fix separation device (1) on window glass at bottom right
- Depending on accessibility, attach bit holder (2) or angle gear (3) to cordless screwdriver (4)
- Place cordless screwdriver (4) on separation device (1) and start winding cord, observe direction of rotation on separation device
If required, over trim panel components with plastic protection
Guide cord with plastic protection around sharp-edged positions
Cut through adhesive bead up to bottom area of A-pillar
Turn back cordless screwdriver (4) approx. 2 rotations and remove
Cutting out procedure
- Discharge vacuum on windshield removal tool (1) by pressing the lug. Remove windshield removal tool (1) from window glass
- Reset removal tool (1) as illustrated and wind up cord up to the position of windshield removal tool (1)
- Repeat further resetting, work sequence as given at B
- Repeat further resetting, work sequence as given at B
Additional resetting may be required for very curved window glass
It is possible to reuse the cord. When a cord is used many times the risk of ripping increases
Dirt contamination must be avoided when a cord is reused
