5. Assembly is carried out in the reverse order, but at the same time tighten the anchor bolts with the specified force Specification.
6. On models equipped with the Procon-Ten restraint system, note that the front inertia reels are permanently attached to the system cable. Therefore, the cable must be removed along with the seat belts. This involves removing the front pillar trim, manual air dam control (if any), disconnecting the cable holder at the rear of the gearbox and replacing all plastic guides. In view of the safety aspect, it is recommended that this work be carried out by an Audi dealer.
