Model Line:
Macan (95B)
Model Year:
As of 2014 up to 2024
Equipment:
Large roof system (M No. 3FU)
Concerns:
Glass sunroof
Information:
Customers complain that the glass sunroof cannot be opened and the fault code “C13214 –
Sunroof/panoramic roof motor – no communication” is stored in the fault memory of the rear-end
electronics control unit.
This is caused by corrosion of the control board of the glass sunroof motor, which is not completely
sealed against water leaking in.
Cause:
The control board of the glass sunroof motor may be corroded if water penetrates up to it.
Water can penetrate as far as the glass sunroof motor because the guide rails for the roof assembly
frame (glass sunroof/panoramic roof) are not sufficiently sealed against water leaking in.
Measures:
•
•
•
•
•
•
Replace defective motor for glass sunroof.
Install additional butyl locks in the guide rail under the front glass panel.
Check front butyl locks for leaks and replace them if necessary.
Check rear butyl locks for leaks and replace them if necessary.
Remove roof assembly (panoramic roof) and attach additional butyl locks to the upper bars of the
guide rails for the roof assembly frame at a center position between both glass panels. Install roof
assembly (panoramic roof).
Check seals on the glass sunroof for gaps. Remove any gaps by correcting the install of the seals
and the installation positions of the glass panels. Replace roof assembly seals if necessary.
