Tightening the securing screw for the dipstick guide tube:
  Note!
t  A self-taping bolt is used, as standard, to secure the dipstick guide tube to the plastic intake manifold. If this bolt is loosened or tightened with a power tool there is a danger of damaging the thread in the intake manifold.
t  For this reason the use of a power tool can only be authorized when:
t  The power tool maximum speed is 200 rpm.
t  The tightening torque is set to a maximum of 3 Nm.
