Service Information (Instructions to technician)
Repairing the coaxial cable will require parts that are particular to the needed application. A single complete coaxial cable is no longer
available for order. Therefore, follow this basic concept to order the correct parts:
Ordering Coaxial Cable
1. Determine the specific length of base coaxial cable needed. Note: 300 mm is approximately 12 inches. (See figure 1 for a G2 Panamera example.)
a. For E3 Cayenne, see PET 911-020 item 2
b. For G2 Panamera, see PET 911-020 item 3
