Issue Description
On the affected vehicles, the brake line screw
connection on the front and rear axles may not have
been fully tightened to the prescribed final tightening
torque.
In this case, leakage in the brake system over the service life cannot be ruled out. The vehicles showed no
leakage during factory testing. The brake system remains fully functional and the legally required minimum deceleration is maintained even in the event of a
failure.
For this reason, the screw connections of the brake lines on the front and rear axle must be checked and
tightened to the specified final tightening torque or the
brake lines replaced, depending on the test result.
What Dealers Should do
Please arrange for this measure to be carried out as
soon as possible on affected vehicles. As of the time
of this posting (3/17/23), the repair is immediately
available.
Parts can be ordered via PPL as needed.
Please note that the expected replacement rate of
the brake lines is 1% of vehicles.
