t  In order to be able to securely attach the air hoses on their connections, the worm screws of the used hose clips have to be sprayed with penetrating spray before installing.
  Caution
The screw-type clips -A- on the charge air lines must always be tightened as specified → Fig.. If the torque is too low or too high, the charge air hose may slip off the corrugated pipe connection or the charge air pipe when the vehicle is used.
