Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Roof Hatch
The sunroof is equipped with a sunroof module (SRM) (4/33) that handles its functions. The sunroof is operated via a switch on the roof panel.
The Central electronic module (CEM) (4/56) transmits information about the vehicle's speed to the Sun roof module (SRM). This information is used to calculate how much force is required from the motors to operate the sun roof. The Sun roof module (SRM) also receives signals from the Central electronic module (CEM), via a directly connected cable, whether to carry out a "comfort open" or "comfort close" or to carry out a sun roof initialization.
