Important: When removing the
centre silencer, a catalytic converter, an exhaust manifold or an
exhaust manifold with catalytic converter, the exhaust system piece
remaining in the vehicle must be secured against uncontrolled
sagging. Bends in the flex pipe by as little as 5 - 10 angle
degrees or a twist through +/- 0.5 ° from the specified
installation position can lead to damage with subsequent complete
failure of the flex pipe. The exhaust system fastening clamps must
be replaced every time they are removed.
When replacing the exhaust system, the transport fixing must first
be removed after installation and before commissioning. This should
be stored for other work in which the exhaust system must be
removed and used to secure the flex pipe.
