Step 3: Modifying / Replacing the big plastic roof cover
Modifying the existing big plastic roof cover
The big part of the roof has a mark in the center, where we have to make a small hole with a suitable multi-tool-drill from which the cables will pass.
Replacing the big plastic roof cover
The big part of the roof, which has the hole for the cabling ready, has a part number of 1Q0 867 390N 82V and is priced around 45 euros. At first we had formed the existing piece of the roof, but unfortunately this way the sensor did not work properly as it did not fit properly.
As a better solution, therefore, it is proposed to replace the large part of the roof.
