  6. Install a new BMW wiper switch in reverse order.
  7. Torque the steering wheel bolt to specification. 
  8. Reinstall the driver's airbag.
  9. Reconnect the negative battery terminal and check the operation of the windshield wiper switch. 

Note that if you moved or rotated the clock spring, you may need to calibrate the steering angle sensor. Follow this guide to learn more about the BMW steering angle sensor and calibration procedure.

If the wipers on your BMW have stopped working, first, you need to check the fuse and the wiper motor.

Next, you need to read BMW fault codes to ensure that the problem is not the SZL module.

If the BMW wipers still do not work, the wiper switch itself could be the issue.

Step 5 "Once the bolts are removed you can pull out the wiper switch and unplug it." There is a ribbon connecting the switch unit to the SLZ unit. How do I disconnect this? Cheers

Airbag Removal Tips & Warnings


  • Always disconnect the battery terminals, press the horn twice then wait at least 10 minutes before working on airbags. 
  • Don't Probe The Airbag With Your Multi-Meter
  • Always handle airbags with care. Do not drop an airbag. 
  • Many airbags are designed to destroy the protective covers they’re concealed in, such as plastic A-pillar or B-pillar trim, seat bolsters, passenger dashboard covers, pillar or B-pillar trim, seat bolsters, passenger dashboard covers, pillar trim, seat bolsters, passenger dashboard covers, etc. 
  • Airbags deploy with significant force and can not only damage peripheral and supporting parts, but the damage may not be apparent. This can include electronics, collapsible steering columns, ignition and brake interlocks, instruments, glass and more.
  • Airbag sensors, which trigger the deployment, are often single-use designs, using a sliding, inertia-driven ball and a membrane. Once activated, these sensors will need replacement too to operate in case of another accident.
  • Accidents that are serious enough to activate the airbags will often trigger the active restraints. That means that the seat belts will also need to be inspected and possibly replaced. Many vehicle restraints use a small explosive charge to tighten the belt by a few inches in an accident. Once that retractor is activated, it must be replaced.
